[0002] Fascia tissue is a layer of fibrous tissue that operates as a connective tissue that surrounds muscles, groups of muscles, nerves, blood vessels, etc. The tissue allows for proper functioning of muscles with respect to one another (e.g., sliding past one another). When fascia tissue becomes damaged through injury, tissue knots, adhesions in the fascia tissue, medical reasons, or otherwise, the fascia tissue can take time to correct itself or require manipulation to release the fascia tissue and allow for proper functioning of the tissue to allow the underlying muscle to properly operate. In some cases, the fascia tissue can be released or corrected without much difficulty, while in other cases, restoring the fascia tissue to its proper form can take considerably more effort. Other reasons for releasing fascia tissue may include cosmetic reasons, especially for people who have dimpled skin, which is often caused by fascia tissue extending through fat cells, thus causing dimples to appear on the skin. Often, when the fascia tissue is properly released, the dimples can be considerably reduced or eliminated.

[0003] Fascia tissue is both structural and inter-structural. Fascial tissue is located throughout the human (and other animals) bodies, including attaching to skin, forming a casing over muscles, forming inter-muscular layers (myofascial tissue), being positioned at lower depths of layered muscles, surrounding organs, and located around bones. For the lower depth fascia, especially when multiple muscles stacked are stacked, adhesions of the -1- 4912-2944-4505Atty. Dkt. No.: NEXC.002WO (125194-2505)fascia tissue or other fascia tissue structure misalignments or damage can result in a variety of discomforts or worse problems, such as circulatory flow, pain, misalignment of muscles and bones, joint problems, and so forth. As such, there is a need to treat fascia tissue at any location of the body.

[0004] Fascia tissue treatment is complicated and scientifically challenging to diagnose and treat. The diagnosis and understanding of a myriad of problems that result from damaged or misaligned fascia tissue is not well understood, and, thus, often not properly treated. For example, pain, circulatory problems, and other physical ailments are often treated using pain medicine, surgery, heating pads, conventional massage, chiropractor join adjustment, and many other medical treatments that essentially treat the symptom and not the cause of the physical ailments that stem from damaged or misaligned fascia tissue. Moreover, even if diagnosed, the ability to treat the fascia tissue, especially myofascial tissue, can be difficult because tools to treat such tissue are limited and generally not configured for such treatments.SUMMARY

[0005] To overcome the problem of having limited tools for treating fascia tissue, the principles described herein provide for treating a wide variety of fascia tissue that may be positioned throughout the body, human and animal. The tools described herein are configured to treat or remodel (e.g., removal of adhesions, realignment, etc.) fascia tissue at depths and orientations that cannot be achieved using other tools to massage techniques. For example, rollers, nubs, or devices with other configurations generally are not capable of penetrating muscle casing or surface of a muscle, much less layered muscle (e.g., two or three layers of muscle of quadriceps muscles). To properly treat the fascia tissue, powered (and unpowered) devices with effectors (e.g., fingers of a certain configuration connected to a panel) create a “fascial shearing” that triggers the body’s natural mechanism to remodel or restructure the fascia tissue that has been damaged or is disfigured in a manner that results in negative effects on the human body.

[0006] One embodiment of the present disclosure relates to a treatment device, including: a housing defining a cavity and a housing surface, the housing surface defining: a grip region having a first diameter; a distal region having a second diameter that is larger than the first diameter; a battery disposed within the cavity at the grip region; electronics in electrical communication with the battery; a motor disposed within the cavity at the distal region, the electronics configured to drive the motor, the motor including: a stator, and a rotorAtty.

[0026] Another embodiment of the present disclosure relates to a powered treatment device for fascia tissue fitness, including a treatment head and a treatment assembly. The treatment head includes: a housing; a mounting and drive system including: an actuator coupled to and disposed substantially within the housing; and a connector element spaced radially apart from a rotational axis of the actuator. The treatment assembly is configured to be removably coupled to the actuator by the connector element.

[0027] Another embodiment of the present disclosure relates to a powered treatment kit for fascia tissue fitness, including a treatment head, a first treatment assembly, and a second treatment assembly. The treatment head includes a housing and an actuator coupled to and disposed substantially within the housing. The first treatment assembly is configured to be removably coupled to the actuator, the first treatment assembly includes a first treatment element rigidly coupled thereto. The second treatment assembly is configured to be removably coupled to the actuator, the second treatment assembly including a second treatment element that is flexibly coupled thereto to enable relative axial movement between the second treatment element and the treatment head when the second treatment assembly is coupled to the treatment head.

[0028] Another embodiment of the present disclosure relates to a method including: providing a treatment head having a housing and an actuator disposed substantially within the housing; providing a tissue treatment assembly; and coupling the tissue treatment assembly to a connecting element of the treatment head that is rotatably coupled to the actuator and that is radially spaced apart from a rotational axis of the actuator such that rotational movement of the tissue treatment assembly is driven by the actuator.

[0029] A fascia tissue treatment system may include a base station that powers tissue treatment devices that are used to treat fascia or other tissue of patients. The tissue treatment devices may be powered devices, and include actuators that are used to move tissue treatment elements. The actuators may be motors that cause an effector inclusive of a support structure, such as a disc or other shaped structural member, on which the tissue treatment elements are connected or formed. In an embodiment, the effector may be a unitary piece, where a supportAtty. Dkt. No.: NEXC.002WO (125194-2505)structure and protrusions or fingers extend. Alternatively, the fingers may be detachably coupled to the support structure. The fingers may have a base that connects to or is integrated with the support structure, curved shafts, and rounded tips.

[0030] In at least one embodiment, the tissue treatment elements may form part of a tissue treatment assembly that is configured for rotation by the actuator in an ON state. The tissue treatment assembly may be uniquely designed to improve treatment effectiveness based on the direction of movement of the actuator. For example, the tissue treatment assembly may include a panel and a plurality of finger members that are shaped based on a rotational direction of the actuator or panel. In at least one implementation, the finger members are curved away from the panel along at least one of a radial direction and / or a circumferential direction of the panel, which can also increase the strength of the finger members during operation and in response to application of axial pressure acting on the finger members during treatment.

[0031] In operation, base station may be utilized to provide electrical power (or other power source types) to provide tissue treatment functions, such as warm-up, tissue release, and / or tissue treatment. The base station may support (i) a heater, such as an infrared heater element, to warm up tissue of a patient, (ii) an ultrasound and / or radio frequency (RF) device to provide for tissue release, and tissue treatment devices of different configurations to provide for fascia or other tissue treatment.

[0032] Moreover, the tissue treatment device may receive electrical power that drives a rotating motor therein. The motor may cause the effector to spin. An operator, either a medical professional or a patient him or herself, may engage the tissue treatment device to cause the effector to spin while pressing the effector onto a patient’s skin. The amount of force being applied may vary depending on a modality being performed along with a particular location on the patient’s body being treated. For example, treatment to a face or scalp uses much less force than body parts with larger surface area and more dense tissue (e.g., muscle). Moreover, if fascia tissue being treated is causing acute pain, then less force and, possibly, less speed of the rotating effector may be used. It should be understood that a wide variety of treatment protocols may be utilized. Moreover, although a spinning effector may be utilized, other actuator types and effectors may be utilized. For example, motors that cause an effector, such as a square or rectangular effector, to cause the effector to move linearly (e.g., forward and backward along a single axis). Powered tissue treatment devices may be utilized, as well, and have a variety of different controllers.Atty. Dkt. No.: NEXC.002WO (125194-2505)

The computing device may capture the ultrasound images and / or visual images and store those images for later viewing. Additionally, the computing device may compare the images over time to assist an operator in determining how past treatments have resulted in improving tissue of the patient. In an embodiment, artificial intelligence (Al) software may be utilized to identify fascia tissue or other tissue abnormalities or structural issues to aid an operator understand how treatments are to be made. In an embodiment, the computing device may be configured to recognize certain structural issues with fascia tissue and aid or recommend to an operator or other medical professional in creating a treatment plan.

The plurality of finger members may be fixedly coupled to the panel at a proximal end of the respective finger members. The finger members may be rigid and extend away from the panel. Each one of the finger members may have a respective central axis that extends from the proximal end to a distal end of the respective finger member. At least one of the central axes may extend at least partly along a radial direction and / or a circumferential direction of the panel.

[0035] Another embodiment of the present disclosure relates to a tissue treatment assembly that includes a panel, a support member, and a plurality of finger members.

[0037] In some embodiments, the controller is configured to control activation of the actuator based on the force applied to the actuator.

[0038] In some embodiments, the controller is configured to control an operating speed of the actuator proportional to the force applied to the actuator.

[0039] In some embodiments, the powered treatment device further includes a user interface having a switch that is communicably coupled to the controller.

[0087] Existing fascia tissue treatment devices require manual manipulation by a user to move tissue treatment elements across a patient’s skin. While effective, users performing self-treatment using hand-held tools may not use sufficient forces and / or speeds to ensure adequate treatment of the fascia tissue. Additionally, due to the forces involved, the tissue treatment elements for existing fascia tissue treatment devices are rigidly supported in fixed positions along the device, which can make them difficult to use in non-planar body areas. Conventional motorized scalp or tissue massagers are not designed to release fascia tissue. For example, the messaging and / or brush elements employed by these conventional systems are specifically designed for user comfort and skin surface treatment, but are not suitable forAtty. Dkt. No.: NEXC.002WO (125194-2505)working the underlying tissue in a manner meant to improve fascia tissue fitness to perform restructuring of fascia tissue at different layers starting at the skin and working down towards or even to the bone. Additionally, fascia tissue treatment may utilize considerable application of force between the tissue treatment elements and a person or patient’s skin, which may cause stress to an actuator being used to drive the tissue treatment elements, thereby resulting in premature failure of the actuator. Such stress, for example, may be caused by using forces in treating fascia tissue that higher torque has to be produced by the actuator, which may result in heat produced in the actuator due to high current draw therein. As such, various configurations of actuators and tissue treatment elements may be utilized to avoid such high-torque situations. It should be understood that the fascia tissue treatments are meant to be applied to lubricated skin of a patient, where the lubrication may be any fluid, such as oil, applied to the skin that reduces friction between tissue treatment elements, such as protrusions (e.g., fingers), of an effector of the tissue treatment device. Alternatively, a cover, such as a sleeve formed of a slick external material, may be placed on skin of a user to enable the tissue treatment device to be applied to the cover to avoid or use a minimal amount of lubrication.

[0088] Referring to the Figures generally, fascia tissue therapy devices are shown that address the foregoing issues and provide multiple options for customizing treatment based on a user’s needs, body physiology, and preferences. The treatment devices of the present disclosure include a treatment head inclusive of a housing, an actuator, and tissue treatment element that is actuated (e.g., rotated, vibrated, linearly translated, etc.) by the actuator. The tissue treatment element may form part of an effector supported by the treatment head (e.g., that is detachably coupled to the treatment head).

[0089] In an embodiment, the therapy device may include a direct drive motor and an effector that is detachably coupled to the therapy device and powered into rotation (or otherwise) by the direct drive motor. Unlike existing powered devices, which typically use a transmission (e.g., gear, gear set, etc.) to achieve the high speeds required for operation, the direct drive motor of the present disclosure may be coupled to the effector without an intervening transmission or gear set. Using a direct drive motor may reduce heat generation and wear on the treatment device as compared to a typical motor that utilizes a gear box, thereby allowing use of the device over longer treatment intervals and with less risk of changes in performance during treatment. A high torque-to-weight ratio of the direct drive motor may also provide a lower weight of the therapy device as compared to a therapy deviceAtty. Dkt. No.: NEXC.002WO (125194-2505)that uses a non-direct drive motor that includes gears, cooling fluid and channels through which the cooling fluid flows, etc.

[0090] The effector for the treatment device may be structured to engage a patient’s skin and manipulate the fascia tissue to restore and restructure the fascia tissue to its proper form. In being structured to engage a patient’s skin, the effector may be shaped to avoid cutting, scraping, or otherwise harm a patient’s skin while being configured to treat the fascia tissue beneath the skin. In contrast with conventional motorized scalp or tissue massager designs, the effector and / or tissue treatment assembly of the present disclosure may be shaped or otherwise structured based on a direction of movement of the effector during treatment to improve treatment effectiveness as compared to effector designs that are not oriented with the direction of travel of the effector. As described herein, the system may be used to treat the fascia tissue at different levels (e.g., shallow, medium depth, deep) depending on the modality and location of the patient (e.g., face may be shallow, arm may range from shallow to medium, leg may range from shallow to deep), and the forces applied to the treatment devices / assemblies by the user. In some embodiments, the effector may be configured to treat shallow, medium depth, or deep tissue. For example, the shape of the effector and fingers (or other features) that are to contact a patient’s skin may have different lengths, widths, tip diameters, curve angles, or other dimensions to be used for shallow, medium depth, or deep tissue. Shallow may mean up to one-tenth of an inch, medium depth may mean up to one inch, and deep tissue may mean more than one inch. It should be understood that alternative ranges may be utilized.

[0091] The effector may include a panel (e.g., a support structure, etc.) and / or plate that is detachably coupled to the treatment device and that includes multiple tissue treatment elements. In some embodiments, the panel may include a mount at an intermediate radial position along the panel that connects the panel to the treatment device to reduce a torque required to maintain movement of the panel during operation. The panel may also include supports and / or be shaped to ensure uniform contact between the tissue treatment elements and the patient’s skin across the face of the panel. In an embodiment, the panel may be flat, round, and have the protrusions e.g., tissue treatment elements) on one side of the panel. However, it should be appreciated that “panel” as used herein also includes various other support structure shapes. For example, in some embodiments, the panel may be curved or rounded (e.g., parabolic) from a base portion to a tip with the tissue treatment elements connected to and radially extending therefrom. In yet other embodiments, the panel can include other non-flat structures such as a waffle structure, a honeycomb-shaped structure, aAtty. Dkt. No.: NEXC.002WO (125194-2505)dome and / or conical extension and / or protrusion. In further embodiments, the panel may include or be formed from a non-contiguous structure such as ribs, bars, standoff-bridges, etc.

[0092] The tissue treatment elements may include a plurality of rigid (e.g., inflexible, stiff, or not easily bent, etc.) protrusions (e.g., fingers and / or finger members, wave shape, pyramid shape with curved tips, spline, or other geometric or non-geometric shape) that extend axially away from the panel. In further contrast to conventional motorized scalp and tissue massagers, the effectors of the present application may be specifically structured to manipulate fascia tissue layers below the skin surface and to take advantage of the direction of movement of the effector during treatment to improve overall treatment effectiveness. For example, tissue treatment elements (e.g., fingers) may extend away from panel (e.g., flat circular member) at an angle (e.g., along a radial direction and / or a direction of rotation of the effector) to improve treatment efficacy and / or allow different treatment modalities depending on the rotational direction of the effector. The tissue treatment elements (e.g., fingers, member that includes one or more fingers that may be connected to a panel, or any other structure that includes elements that contact skin for treating fascia tissue) may have a variety of different shapes, sizes, orientations, alignments, and / or configurations. In one embodiment, the tissue treatment elements (e.g., fingers) may have multiple different sized fingers (e.g., small in the middle and large on the outside of the panel having a flat, circular shape or any other shape that may or may not be flat).

[0093] In some embodiments, rotation of the treatment assembly and / or the treatment elements of the treatment assembly relative to the treatment head may be controlled responsive to the application of force between a user and the treatment device, such as responsive to pressing the treatment assembly against a patient’s skin, and / or responsive to different levels of force applied by a user to press the treatment device against the patient’s skin and / or to different locations across the treatment assembly.

[0094] In at least one embodiment, the treatment assembly includes treatment elements that are movable with respect to one another, and / or with respect to other treatment elements along the treatment assembly, to provide approximately uniform application of force between the treatment elements across the treatment assembly and the patient’s skin. In some embodiments, the treatment assembly is configured to enable movement of treatment elements relative to one another responsive to the application of force between different regions of the treatment assembly and the patient’s skin. For example, the treatment elements may be arranged on a plurality of treatment element panels that are independently secured to a common support panel of the treatment assembly. The treatment assembly may furtherAtty. Dkt. No.: NEXC.002WO (125194-2505)include spring elements engaging the support panel that resist compression of the treatment elements towards the panel during use, and thereby enabling a more uniform application of force along curved body areas as compared to a treatment assembly having treatment elements that are fixedly coupled along the same plane.

[0095] The treatment elements may include at least one rigid (e.g., inflexible, stiff, not easily bent, etc.) protrusion (e.g., fingers and / or finger members) that extends axially away from a respective one of the treatment element panels. The fingers may be elongated and curved, and extend away from the treatment element panel at an angle (e.g., along a direction of rotation of the treatment assembly), which can improve treatment efficacy and / or allow different treatment modalities depending on the rotational direction of the treatment assembly. In contrast to motorized scalp and tissue massagers, the treatment assemblies of the present application may be specifically structured to manipulate fascia tissue layers below the skin surface.

[0096] Referring to FIGS. 1A-1D, a tissue treatment device (e.g., a tissue therapy device, etc.), shown as treatment device 100 is shown that is configured to power movement of tissue treatment elements for fascia tissue treatment (e.g., to apply a treatment to a user by moving a tissue treatment assembly along a user’s skin, etc.). The treatment device 100 includes a treatment head 102, a user interface element (e.g., a replaceable cap, grip, and / or handle, shown as cap 104), one or more gripper surfaces, shown as a second grip 106 that is attached or integrated with a housing 108, and a treatment assembly 110. In other embodiments, the treatment device 100 may include additional, fewer, and / or different elements.

[0097] The treatment head 102, which may also be referred to as a head and / or an actuator assembly, includes (i) a housing 108; (ii) an actuator 112 (e.g., brushless DC motor) disposed within the housing 108, and configured to power the treatment assembly 110; and (iii) a control system 114. In some embodiments, the control system 114 includes a sensor 116 (e.g., pressure, speed, torque, temperature, etc.), a user interface 118, a heating element (e.g., an infrared (IR) lighting), and / or other electronic components, as will be further described.

[0098] In some embodiments, the treatment device 100 may be configured for use with a variety of different user interface elements (e.g., handles, grips, etc.) and different treatment assemblies configured to be detachably coupled to the treatment head 102. Such an arrangement enables use of the treatment device 100 in different body areas and to applyAtty. Dkt. No.: NEXC.002WO (125194-2505)forces from different vantage points relative to a patient’ s / clinician’s body to perform a variety of treatment modalities.

[0099] In the embodiment of FIGS. 1A-1D, the treatment device 100 includes a first quick-connect interface 122, such as a chuck, snap-fit connector, and / or another form of detachable coupling to facilitate removal and replacement of the user interface element and a second quick-connect interface 124 to facilitate removal and replacement of the treatment assembly 110. In the embodiment of FIGS. 1A-1D, the first quick-connect interface 122 of the treatment device 100 may be spaced apart from the second quick-connect interface 124 by the housing 108 (e.g., on opposing sides of the housing 108) along an axial direction relative to a central axis (e.g., a rotational axis, etc.) of the housing 108. It should be understood that alternative configurations may also be used for connecting and disconnecting the treatment assembly 110 and housing 108.

[0100] The user interface element may be configured to facilitate manual manipulation of the treatment device 100 by a user (e.g., a clinician, a patient, etc.), and application of force between the user and the patient’s body. In the embodiment of FIGS. 1A-1D, the user interface element is a handle 107 that is configured to be detachably coupled to an end of the housing 108 along the axial direction. In some embodiments, the handle 107 includes a grip 105, such as one or more pads that may be made from a flexible rubber and / or plastic material (e.g., silicone), or another material to facilitate manual interaction with the handle 107. Using a silicone material can provide a pleasing “velvety” feel to the user when manipulating the therapy device. As shown in FIGS. 1A-1D, the user interface element may also include a second grip 106 that may cover a portion of the handle 107. In other embodiments, the second grip 106 may extend across only a portion of the handle 107. The second grip 106 on the handle 107 may have alternative shapes, such as being circular (e.g., disk, ring with or without spokes, cross (e.g., two parts that may or may not be tubular), diamond, or any other geometric or non-geometric shaped features that enable a user to grip and apply force during treatment to a patient).

[0101] Moreover, the size and shape of the user interface element (e.g., the handle, etc.) may be different in various embodiments. For example, referring to FIG. 2, a user interface element 204 is shown that includes handle in the form of a tubular bar 209 having an elongated cylindrical shaft having a circular cross-sectional profile. The user interface element 204 may be solid or hollow and the walls may be solid or include apertures depending on the strength, weight, or other structural and / or functional criteria. In other embodiments, a cross-sectional shape of the handle may be different. A central axis of theAtty. Dkt. No.: NEXC.002WO (125194-2505)elongated cylindrical shaft extends substantially normal to the central axis (e.g., the rotational axis) of the treatment head 202. The first quick-connect interface 222 is disposed at an intermediate position along the handle (e.g., at a midpoint between opposing ends of the handle), and extends radially away from a central axis of the elongated cylindrical shaft. A non-quick-connect feature may alternatively be used to secure the user interface element 204 to the housing in some embodiments (e.g., a threaded interface, etc.).

[0102] Referring again to FIGS. 1A-1D, the treatment device 100 may be structured for use both with and without the handle depending on how the user chooses to interact with the treatment device 100. The configuration of the treatment device 100 may, in part, depend on modalities to be performed (e.g., a smaller user interface region, closer to the housing 108 may be beneficial when working the device over smaller and / or curved body areas). As shown in FIGS. 1A-1D, the middle portion of the housing is shaped so that a user may wrap one of his or her hands around the middle portion, which can be used to guide the treatment device 100 across a patient’s skin. The housing 108 may include grips (e.g., the second grip 106 in the form of pads that enhance a user’s grip on the device. The housing 108 may alternatively have different shapes and / or features to provide the user with different grip capabilities. Moreover, dimensions of the housing 108 may be different depending on whether the treatment device 100 is configured to treat large or small body parts (e.g., forearms, hands, neck, calves, and feet might be more easily treated with a smaller treatment device).

[0103] In some embodiments, and as shown in FIG. IB and FIG. 1C, the treatment device 100 includes a housing 108 defining a cavity 101 and a housing surface 139. The housing 108 extends along a longitudinal axis between a proximal end (e.g., a first axial end) and an opposite, distal end (e.g., a second axial end). The cavity 101 is configured to receive and enclose internal components of the treatment device 100, such as the battery 135, the motor 137, and associated electronics. The housing surface defines a grip region 113 having a first diameter 131 and a distal region 115 having a second diameter 133 that is larger than the first diameter 131. The grip region 113 is positioned proximate to the proximal end of the housing 108, while the distal region 115 is positioned proximate to the distal end of the housing 108, such as proximate to the tissue treatment effector.

[0104] A transition between the first diameter 131 and the second diameter 133 can provide structural advantages during operation of the treatment device 100. For example, the shape of the housing 108, extending to a larger (e.g., flared) distal region, which may be proximate to the effector, facilitates improved retention and control of the treatment deviceAtty. Dkt. No.: NEXC.002WO (125194-2505)100 during fascia tissue treatment. The grip region 113 having the first diameter 131 is sized to be comfortably grasped by a user's hand, allowing the user to maintain a secure grip while applying axial force to the treatment device 100 against a patient's tissue. The distal region 115 having the second diameter 133 can provide increased structural rigidity and support to accommodate the motor 137 and to resist bending or deflection when axial forces are applied during treatment (e.g., by a hand of a user positioned across at least a portion of the transition and / or distal region during two hand operation). In some embodiments, the increased diameter of the distal region 115 can improve force distribution across a larger cross-sectional area of the housing 108, thereby reducing stress concentrations within the housing 108. For example, when the tissue treatment effector is rotated by the motor 137 and pressed against a patient's skin with sufficient force to release fascia tissue, the larger second diameter 133 of the distal region 115 resists deformation and maintains alignment of the motor 137 and the tissue treatment effector.

[0105] In some embodiments, and as shown, the housing surface 139 further defines a transition region between the grip region 113 and the distal region 115. In some embodiments, the transition region includes a spline curve 117 that extends from the first diameter 131 to the second diameter 133. The spline curve 117 provides a gradual increase in diameter along the longitudinal axis of the housing 108, which improves ergonomics by conforming to the natural curvature of a user's hand. In some embodiments, the transition region includes a first inflection point 123 at which the housing surface transitions from the first diameter 131 to a larger diameter. The first inflection point 123 may define a concave curve along the housing surface 139. In some embodiments, the transition region includes a second inflection point 127 that defines a convex curve along the housing surface 139. The second inflection point 127 is positioned between the first inflection point 123 and the distal region 115. The combination of the concave curve at the first inflection point 123 and the convex curve at the second inflection point 127 provides a contoured profile that allows the user to position fingers along the transition region to apply controlled axial force during treatment.

[0106] In some embodiments, the transition region includes an abrupt (e.g., stepwise) transition between the grip region 113 and the distal region 115, such as a step, ledge, and / or shelf. The abrupt transition can provide a physical support surface against which a user's finger, such as a pinky finger and / or side of a user's palm, may be positioned to apply axial force to the treatment device 100. For example, when the user grips the grip region 113 and extends the pinky finger downward along the housing surface, the pinky finger engages theAtty. Dkt. No.: NEXC.002WO (125194-2505)step, allowing the user to push the treatment device 100 axially toward the patient's tissue with greater control and force. The step can thereby improve the user's ability to maintain consistent axial pressure during treatment, which is beneficial for releasing fascia tissue at varying depths beneath the skin. The abrupt transition formed by the step can further prevent the user's hand from sliding distally along the housing 108 during treatment, thereby enhancing retention of the treatment device 100 within the user's hand.

[0107] The actuator 112 is configured to power rotation of the treatment assembly 110 relative to the housing 108. The actuator 112 may be directly or indirectly coupled to and disposed within the housing 108. Referring to FIG. 1C, in some embodiments, the actuator 112 includes a motor 137 disposed in the cavity 101, such as adjacent to the distal region. The motor 137 is structured to rotate the treatment assembly 110. In such embodiments, the actuator 112 may include a direct drive motor that engages the treatment assembly 110 without any intervening transmission or gear set. Using a direct drive motor reduces heat produced by the treatment device 100 and wear on the internal components. The direct drive motor may also reduce weight of the treatment device 100 due to the increased torque-to-weight ratio of the motor. In other embodiments, the actuator 112 includes another form of electromechanical device (e.g., brushless direct current motor, electromagnetic device, etc.).

[0108] In yet other embodiments, the actuator 112 may be another form of rotational and / or vibrational device (e.g., an electromagnetic device, etc.). Vibration of the treatment device may be random or non-random. For example, the actuator 112 may be configured to both rotate treatment assembly 110 and vibrate the treatment assembly 110 up-and-down. The actuator 112 may alternatively rotate and randomly vibrate.

[0109] The actuator 112 may include a second quick-connect interface 124, as described above, to couple to a mounting member of the treatment assembly 110 (e.g., a central mounting member that is axially aligned with the distal region such that it is coaxial with the distal region, a peripheral mounting member disposed at an intermediate radial position alone the treatment assembly 110, etc.). For example, the treatment assembly 110 may include a post disposed at a central position on a support panel of the treatment assembly 110. The post may extend axially away from the treatment assembly 110. The post may be configured to be received within a chuck or another quick-connect interface of the actuator 112. In other embodiments, the actuator 112 may engage the treatment assembly 110 at an intermediate radial position approximately half-way between a central axis of the treatment assembly 110 and an outer perimeter of the treatment assembly 110, or at another intermediate radial position. In yet other embodiments, the actuator 112 may be configured to engage theAtty. Dkt. No.: NEXC.002WO (125194-2505)treatment assembly 110 along an outer perimeter of the treatment assembly 110. Engaging the treatment assembly 110 along an intermediate or outer radial position can reduce torque on the actuator 112 during treatment (due to the smaller moment arm of the treatment assembly 110), reduce deflection of the treatment assembly 110 under an applied axial force, and ensure more uniform engagement between the treatment elements of the treatment assembly 110 and a user’s fascia tissue during use.

[0110] In some embodiments, and as shown in FIG. 1C, the treatment device 100 includes a battery 135 disposed within the cavity 101 at the grip region 113. The battery 135 may be positioned along a central axis of the housing 108 and extend axially from a proximal end of the cavity 101 toward the motor 137. In some embodiments, the battery 135 may be a rechargeable lithium-ion battery, a nickel-metal hydride battery, or another rechargeable battery type. The battery 135 is in electrical communication with electronics that drive the motor 137, thereby providing electrical power to the treatment device 100 during operation.

[0111] In some embodiments, the treatment device 100 includes a cap 104 detachably coupled to a proximal end of the housing 108 and enclosing the battery 135 within the cavity 101. The cap 104 is threadably coupled to the housing 108, which enables removal of the cap 104 for battery replacement and / or recharging. For example, a user may unthread the cap 104 to access the battery 135, remove a depleted battery 135, insert a replacement battery 135, and rethread the cap 104 to secure the battery 135 within the cavity 101. The cap 104 may include a textured outer surface and / or a raised profile that facilitates manual engagement by the user during removal and installation. In some embodiments, the cap 104 is formed from a material having a higher coefficient of friction than the housing 108, such as a rubber and / or silicone material, which improves grip during operation of the treatment device 100. The replaceable cap 104 that encloses and secures the battery 135 within the cavity 101 also provides an alternative gripping structure, allowing the user to grasp the cap 104 at the proximal end of the housing 108 while applying axial force to the treatment device 100 during treatment.

[0112] The shape and structure of the housing may be different in various embodiments and depending on the treatment modality. Referring to FIG. 22 A and FIG. 22B, an alternate housing configuration for the device 1200 is shown. The device 1200 includes a housing 1208 defining a housing surface 1209. The housing surface 1209 defines a grip region 1213 and a distal region 1215. In some embodiments, the housing 1208 has a substantially conical shape, frustoconical shape, or bell shape that tapers from a broader upper region toward a narrower lower region. The housing surface 1209 extends outward from the narrower lowerAtty. Dkt. No.: NEXC.002WO (125194-2505)region and flares toward the distal region 1215. The flared profile can improve retention of the treatment device 1200 by a user, and / or transmission and / or distribution of axial force across the device.

[0113] In some embodiments, the housing 1208 has a curved profile, such as a circular profile, which can improve ergonomics. In some embodiments, a cross-sectional profile of the housing 1208 taken perpendicular to a longitudinal axis of the device 1200 may be elliptical or another curved shape instead of circular. In some embodiments, the cross-sectional profile may be non-circular and formed from a curved profile having a major axis and a minor axis. In some embodiments, the cross-sectional profile may be formed from straight line sections arranged to define a polygonal perimeter, such as an octagonal perimeter, a hexagonal perimeter, or another multi-sided perimeter, among others. The grip region 1213 surrounds the housing 1208 along an intermediate axial region between the upper end and the distal region 1215. In some embodiments, control buttons, actuators, or switches of the device 1200 may be positioned at opposite axial ends of the housing 1208, for example, at the upper end and proximate to the distal region 1215, instead of at opposite circumferential positions along the housing 1208.

[0114] The control system 114 may be configured to control operation of the actuator 112 as a function of user settings and / or based on sensor data from sensors of the treatment device 100. Referring to FIG. 3, a control system 302 for a treatment assembly is shown, according to an embodiment. The control system 302 includes a treatment assembly controller, shown as controller 304; sensor(s) 306; an actuator 308; and a user interface 310. The sensor(s) 306, the actuator 308, and the user interface 310 are communicably coupled to the controller 304 by a communications interface 312.

[0115] The controller 304 includes a processing circuit 313, which may include one or more processing circuits having memory 316 and one or more processors, shown as a processor 318. The controller 304 also includes modules, control units, and / or control circuits that are configured to facilitate the various operations of the controller 304. In some embodiments, the modules, shown as a treatment monitoring module 320, a select operating parameter module 322, and an activation control module 324, are embodied as machine-readable instructions stored in memory 316 that, when executed by the processor 318, are configured to cause the processor 318 to perform any of the operations described herein. In some embodiments, the modules together form part of a software application for the treatment assembly. In other embodiments, one or more of the modules may be embodied asAtty. Dkt. No.: NEXC.002WO (125194-2505)separate control circuits that are configured to facilitate various individual aspects of treatment assembly operation.

[0116] In some embodiments, the control system 302 includes a “dead man’s” switch, which may include a relay and a sensor (e.g., one of the sensor(s) 306) coupled to or in electrical communication with the relay. The relay may be configured to deactivate the actuator 308 responsive to signals from the sensor. The sensor(s) 306 may be a pressure sensor, an accelerometer, and / or may include other types of sensors that are configured to generate sensor data indicative of whether the treatment device has been dropped or otherwise released, if an impact has occurred, if too great a force is applied to the treatment assembly and / or the treatment head. In some embodiments, the dead man’s switch may be implemented by the treatment monitoring module 320 and the activation control module 324.For example, the treatment monitoring module 320 may be configured to identify, based on sensor data from the sensor(s) 306, that the device has been dropped, an impact has occurred, or another condition indicative of the need to deactivate the actuator (e.g., such as by interpreting the sensor data using one or more lookup tables or device condition algorithms). The activation control module 324 may be configured to control activation of the actuator 308 responsive to signals indicating that the device has been dropped (e.g., by a device condition from the device condition algorithm or lookup table that exceeds or otherwise satisfies a dropped condition).

[0117] The control system 302 also includes a user interface 310 (which may be the same as or similar to the user interface 118 of FIG. 1A), which may include one or more switches to control operation of the actuator 308 and / or other components of the treatment device 100.For example, in the embodiment of FIG. 1A, the user interface 118 may include a first switch 119 (e.g., trigger, button, etc.) that enables and / or controls activation of the actuator 112 and / or activation of the auto shut-off switch and / or “dead man’s” switch (e.g., sensor, accelerometer, etc.) that deactivates and / or locks the actuator 112 under certain circumstances (e.g., the treatment device 100 is dropped or otherwise released, in the event a rapid shut down is otherwise required, as described above). In some embodiments, the auto shut-off switch may prevent the user from turning the device ON until the locking mechanism is released. In some embodiments, the dead man’s switch may also be connected to or in electrical communication with pressure / force and / or torque measurement sensors within the treatment device and / or treatment assembly to automatically shut down the system when certain threshold values are satisfied (e.g., when the pressure and / or torque exceeds threshold values). Still yet, the user interface 118 may include an electronic display to provide a userAtty. Dkt. No.: NEXC.002WO (125194-2505)with information and control features for altering at least one operational parameter (e.g., speed) of the treatment device 100.

[0118] Returning to FIG. 3, the control system 302 (e.g., the controller 304, the select operating parameter module 322, the activation control module 324) may be configured to operate the treatment device between a sleep mode (e.g., a paused mode, a low power mode, etc.) and an awake mode (e.g., an unpaused mode, a higher power mode compared to the sleep mode, etc.). For example, the first switch (e.g., the first switch 119 of FIG. 1A) may be configured to enable operation of the treatment head (e.g., the actuator 308) to an ON state in the sleep mode until a user interacts with the device. In such embodiments, the controller 304 may be configured to activate the actuator 308 responsive to activation of the first switch into a sleep mode or ready mode and to continue operation of the treatment device in the sleep mode to prevent rotation of the actuator 308 until a user picks up (e.g., transition from sleep mode to ready mode), moves (e.g., transition from sleep mode to ready mode), and / or presses the treatment assembly against a patient’s skin (e.g., transition from ready mode to ON mode to initiate driving the actuator 308). The controller 304 (e.g., the treatment monitoring module 320) may be configured to determine (e.g., identify), based on signals and / or sensor data from the sensor(s) 306, movement and / or an orientation of the treatment head or treatment assembly (e.g., the user engaging the treatment assembly with a user’s skin, the user picking up the treatment device, etc.).

[0119] In some embodiments, the sensor(s) 306 includes multiple sensors across the treatment assembly that are configured to generate sensor data indicative of an amount of force or pressure applied to different portions of the treatment assembly and / or an overall force / pressure applied to the treatment assembly. The controller 304 (e.g., the select operating parameter module 322) may be configured to determine a pause condition based on the sensor data, and the controller 304 (e.g., the activation control module 324) may be configured to control the actuator 308 (e.g., to unpause activation of the actuator 308, transition from the ready mode into the ON mode) based on the pause condition (e.g., responsive to sensor data indicative of movement of the treatment device, application of pressure to the treatment assembly, etc.) so that treatment can begin by driving the actuator 308 as driven by the control system 302. In some embodiments, the sensor(s) 306 may alternatively or additionally include a distance sensor. The controller 304 (e.g., the treatment monitoring module 320) may be configured to determine, based on sensor data (e.g., signals) from the distance sensor, a distance between the treatment head (e.g., the treatment head 102 of FIG. 1A) and a patient’s skin. The controller 304 (e.g., the select operating parameterAtty. Dkt. No.: NEXC.002WO (125194-2505)module 322) may be configured to determine whether the distance satisfies a threshold distance (e.g., is within a threshold distance from the patient’s skin or is in contact with). The controller 304 (e.g., the activation control module 324) may be configured to activate the actuator 308 (e.g., from the sleep mode to the ready mode to the ON mode to initiate movement of the treatment assembly) based on the signals from the select operating parameter module 322 (e.g., based on a determination that the distance is within a threshold distance from the patient’s skin or is in contact with.

[0120] In some embodiments, the sensor(s) 306 includes a motion sensor (e.g., an accelerometer, etc.). In such embodiments, the controller 304 may be configured to receive a signal from the motion sensor, sense when the device is in use (e.g., applying a pressure by treatment assembly to a user’s skin, moving back and forth, etc.) and to automatically cause the actuator 308 to turn ON during motion, and to automatically cause the actuator 308 to automatically turn OFF when not in motion not applying pressure to the user’s skin by the treatment assembly, and / or not moving in a particular treatment motion (e.g., rotating, substantially linearly forward / b ackward or side-to-side, where substantially means that there may also be some rotational and / or vibrational movement during operation). One or more pressure sensors (e.g., between the treatment element(s) and panel supporting the fingers) may also be utilized to determine when the treatment assembly is engaged with the patient’s skin and cause the actuator 308 to turn ON and OFF. In an embodiment, a timing circuit may be utilized to maintain the actuator 308 in the ON state for a minimum duration of time (e.g., 2 seconds, 5 seconds, 15 seconds, etc.) and / or to limit operating time of the actuator 308, thereby allowing the user to intermittently lift the treatment device to move to a different location with the actuator during which time the controller 304 may maintain the actuator 308 in an OFF state. Alternatively, a setting may disable the “move” feature such that the actuator 308 remains in an ON state until the user actuates the first switch.

[0121] In some embodiments, the controller 304 may also be configured to control an operating speed based on user inputs to the first switch. For example, the controller 304 may be configured to cycle through various average operating speeds stored in memory based on a number of times that the first switch is depressed or repositioned. In other embodiments, the first switch may include a dial to directly control a speed setting of the actuator 308. In some embodiments, the controller 304 may be configured to provide a notification to a user of the operating speed that corresponds with their selection, and / or to enable continuously variable adjustment of the speed (e.g., by pressing and holding the first switch, or through another user interaction with the first switch). In an embodiment, the controller 304 may be voiceAtty. Dkt. No.: NEXC.002WO (125194-2505)activated (if a microphone were included and in communication with the communications interface 312) and / or speed controlled. In an embodiment, the control system 302 may be configured to initiate driving the treatment assembly slowly and then increasing linearly or non-linearly to an operating speed. In starting slowly, a ramp, spline, asymptotic, or other shape, may be utilized, as further described herein.

[0122] In some embodiments, the controller 304 may be configured to slowly ramp up the operating speed of the actuator 308 at startup, which can prevent injury to the user and / or patient. For example, upon activation of the actuator 308 (e.g., responsive to a signal from the first switch, movement of the treatment device, and / or a force applied to the treatment assembly, etc.), the controller 304 may be configured to increase rotational speed of the actuator 308 based on a ramp function. The ramp function may be a linear and / or a nonlinear increase in the rotational speed, depending on application requirements. In an embodiment, a pressure sensor may be used for sensing pressure and causing the controller 304 to variably, dynamically, and / or automatically increase and / or decrease speed. The pressure-speed control may be a factory setting or an optional setting for the user to select and / or adjust.

[0123] The user interface 310 also includes a second switch (e.g., a second switch 121 as shown in FIG. ID), which may be used to control other functions of the treatment device, such as a heating system and / or activation of at least one light element (e.g., a red infrared or other wavelength light) of the treatment assembly. As shown in FIGS. IB and ID, the first switch 119 and the second switch 121 may be disposed at opposing sides of the housing 108 at an intermediate axial position along the housing 108. In other embodiments, the second switch 121 may also be structured to allow a user to control the speed and / or other functionality of the therapy device. For example, the user interface 118 may also include a setting selector that allows a user to manually adjust operational limits, a control factor that is used by the control system 114 to determine the rotational speed responsive to different forces and / or pressures acting on the treatment device / assembly, and / or other control parameters for the treatment device 100. The treatment device 100 may also include a number of other sensors, such as a timer, impact switch, temperature, angle or orientation sensor, etc., that, if any of the sensors detects a problem (e.g., treatment device is dropped), then the control system 114 may be configured to automatically turn the treatment device 100 to an OFF state.

[0124] The control system 114 may also include a sensor 116 (e.g., at least one of the sensor(s) 306 of FIG. 3) for monitoring device operations, and a transceiver (e.g., WiFi,Atty. Dkt. No.: NEXC.002WO (125194-2505)Bluetooth®, etc., such as the communications interface 312 of FIG. 3) for communicating sensor data and / or user data with other networked systems. The controller 120 may be configured to control operations based on data received from the sensor 116, the user interface 118, and / or the transceiver.

[0125] Returning to FIG. 3, the controller 304 (e.g., the treatment monitoring module 320) may be configured to determine a torque and / or force applied to the treatment device / assembly by a user. The controller 304 (e.g., the select operating parameter module 322) may be configured to determine operating conditions based on the applied torque and / or force. The controller 304 (e.g., the activation control module 324) may be configured to control operation of the actuator 308 to satisfy the operating conditions determined based on the torque and / or force. In some embodiments, at least one of the sensor(s) 306 may be a torque sensor that is structured to generate sensor data indicative of a torque applied to the actuator 308. In other embodiments, at least one of the sensor(s) 306 may be a force and / or pressure sensor that is configured to generate sensor data indicative of a force and / or pressure applied to the actuator 308 and / or the treatment assembly. The controller 304 may be configured to determine the torque and / or force applied to the actuator 308 based on the sensor data, and control the speed of the actuator 308 based on the torque and / or force, as previously described. For example, the controller 304 may be configured to increase or the rotational speed of the actuator 308 proportional to the torque and / or force (e.g., more torque and / or force results in more speed). In some embodiments, determining the speed that corresponds with the torque and / or force includes scaling the torque and / or force by a control factor, which may be stored in memory of the control system 302 or otherwise received by the control system 302 (e.g., from a cloud server or computing device via the transceiver, manually input by a user, etc.).

[0126] In some embodiments, the control system 302 may be configured to provide feedback to the user via the user interface 310 to indicate the measured values of the torque and / or force. For example, the treatment device 100 in FIG. 1A may include multiple indicator lights 109 disposed along an outer perimeter of the housing 108 and facing radially away from or vertical from the housing 108. In other embodiments, the location of the indicator lights on the treatment device 100 may be different. The indicator lights 109 may be configured to provide an indication of the force being applied to the treatment assembly 110 (or a portion of the treatment assembly 110) relative to a target force and / or pressure for treatment. For example, the lights in a first circumferential quadrant of the treatment device 100 may indicate whether the force applied in a nearest quadrant of the treatment assemblyAtty. Dkt. No.: NEXC.002WO (125194-2505)110 is less than a target pressure and / or force based on a color of the lights (e.g., red, yellow, green, blue, etc.), an amount of flashing, and / or other visual indication. In an embodiment, if a target range of forces (i.e., low force threshold and high force threshold) is established for a particular modality or treatment, then in the event that force (e.g., force in a quadrant of the treatment assembly 110) is sensed to be too low, then lights (e.g., light emitting diodes (LEDs)) may be illuminated to be one color (e.g., blue) and if sensed to be too high, then lights may be illuminated to be in another color (e.g., red). If the force and / or pressure is sensed to be within range of the desired treatment levels, then another color (e.g., green) may be displayed by the lights. If sensors configured in quadrants are used, then the feedback (e.g., lights) may be displayed in relation to each pressure measured in the quadrants associated with the sensors in the respective quadrants. Other color schemes may be utilized, as well. Moreover, the pressure sensor feedback signals may be collected by the user interface 118 and stored thereon, thereby enabling the user interface 118 or another computing device to correlate pressure, treatment devices, operator, etc. with fascia tissue restructuring progress, for example.

[0127] The user interface 118 may also include a speaker to provide audible and / or tactile notification of the applied vs. desired level of torque and / or force to a user. For example, if the torque and / or force is too low in one or more areas of the treatment assembly 110, a change of an audible signal (e.g., Geiger counter tones, frequency, pitch, and / or volume of an audible signal, etc.) or a notification signal (e.g., tone, beep, etc.) may be produced. Still yet, the user interface 118 may include an electronic display that may be touch-sensitive to enable a user to adjust settings (e.g., ON state conditions, speed settings, infrared (IR) settings, ramp-up time, etc.), display operational parameters (e.g., speed, force, infrared (IR) strength, etc.) to enable the user to view the settings and / or operating parameters, and / or history data. The electronic display may be illuminated or non-illuminated.

[0128] Returning to FIG. 3, the treatment device may also include sensor(s) 306 that communicate with the controller 304 to determine the correct control parameters and / or treatment protocol based on the treatment assembly (e.g., the treatment head) that is connected to the actuator 308. The controller 304 may also use data from the sensor(s) 306 to monitor operation of the treatment device during treatment (e.g., the average applied force, torque, rotational speed, duration of use, etc.). For example, each treatment assembly may be coded with a type, size, finger or treatment element type, shape, etc. In coding the treatment assembly, chips, such as RFID chips or processor chips or memory chips, may be coded with identifying information, thereby enabling the user interface 310 to receive and record theAtty. Dkt. No.: NEXC.002WO (125194-2505)identification information so that historical records may be maintained in an automatic manner. The controller 304 may record this data in memory at periodic intervals. Data from the sensor(s) 306, can be fed back to a remote computing system via the transceiver (e.g., the communications interface 312) for analysis, and / or input to a machine learning algorithm to update and / or improve treatment prescription.

[0129] Various forms of treatment assemblies may be used with the treatment device. In some embodiments, the treatment device and the treatment assemblies together form a powered treatment kit for treating fascia tissue. Referring to FIGS. 4A-4E, multiple different types of treatment assemblies for use with the treatment device 100 of FIGS. 1A-1D are shown, according to various embodiments. The treatment assemblies shown in FIGS.4A-4E include a first treatment assembly 410a, a second treatment assembly 410b, a third treatment assembly 410c, a fourth treatment assembly 410d, and a fifth treatment assembly 410e

[0130] The first treatment assembly 410a may include a support panel 412a and multiple treatment elements 414a. In the embodiment of FIG. 4A, the treatment elements 414a are fingers 416a extending away from the support panel 412a in an at least partially axial direction with respect to a central axis of the first treatment assembly 410a. The support panel 412a may be rigid. Alternatively, the support panel and / or interface that supports the treatment elements 414a may be flexible. In other embodiments, at least one of the treatment elements 414a includes a finger member (e.g., flower member, etc.) having a central body and multiple fingers extending axially and curving radially away from the central body.

[0131] In the embodiment of FIG. 4A, the fingers 416a may be arranged in at least one ring concentric with the central axis of the first treatment assembly 410a (e.g., in rows along a radial direction). In other embodiments, the fingers 416a may be located in a different arrangement along the support panel 412a. In one embodiment, the treatment elements 414a are mounted to the support panel 412a using a fastener (e.g., screw, bolt, etc.). In other embodiments, the tissue treatment elements 414a may be glued, welded, or otherwise coupled to the support panel 412a. In yet other embodiments, and as shown, the treatment elements 414a are integrally formed with the support panel 412a as a monolithic body from a single piece of material. The treatment elements 414a, including the fingers, may be formed of metal or another material that may be sanitized after use without damage. In other embodiments, the treatment elements 414a may be formed from acrylic, PVC, hard rubber, or any other material that is rigid (e.g., stiff, inflexible, non-flexible and / or non-bendable under the weight of an average person, having a modulus of elasticity above approximately 0.02Atty. Dkt. No.: NEXC.002WO (125194-2505)GPa, 0.05 GPa, 0.1 GPa, or greater) and does not cut or scrape skin of a patient on which the effector is being utilized to help treat or adjust fascia tissue. It will be appreciated that alternative numbers of treatment elements 414a may be utilized in accordance with the principles of the present disclosure. The treatment elements 414a are also shown to be substantially identical. However, it will be appreciated that alternative configurations of the treatment elements 414a may be utilized to provide for treating different size anatomical regions.

[0132] The dimensions of the fingers 416a may be different in various embodiments (e.g., / i inch to 6 inches in diameter, etc.). Illustrative fingers 416a for the first treatment assembly 410a shown are about3 / 4 of an inch long and have heads or tips that are about 3 / 8 of an inch across. The dimensions and configurations (e.g., curves) of the treatment elements, finger members, and tips of the finger members may vary depending on the anatomical region on which the treatment assembly is to be used. The dimensions of the support panel 412a may also be different in various embodiments.

[0133] For example, the second treatment assembly 410b of FIG. 4B may include fingers 416b that are approximately the same size as the fingers 416a, but are mounted to a support panel 412b having an outer diameter that is approximately half of the outer diameter of the support panel 412a of the first treatment assembly 410a (e.g., an outer diameter of approximately 3.5 inches for the support panel 412b as compared to an outer diameter of approximately 5.5 inches for the support panel 412a). The outer diameter of the support panel may be different in various embodiments. A thickness of the support panel 412a and the support panel 412b is approximately 1 inch, but may also be different in various embodiments. By way of another example, the third treatment assembly 410c may include a support panel 412c having the same dimensions as the support panel 412b, but that includes fingers 416c that are approximately double the size of the fingers 416b.

[0134] As shown for the first treatment assembly 410a of FIG. 4A, the tips of the fingers 416a may have one or more same or different dimensions as a body portion of the fingers 316a that extends from the support panel 412a (e.g., the tips may be bulbous and have a larger diameter than the body portion, the outer diameter of the fingers 316a, normal to a central axis of the fingers 416a, may increase continuously from the support panel and into the tip). An outer surface of the fingers 416a may be smooth and continuous without any local protrusions or local indentations along the fingers 416a (e.g., without any mathematical discontinuities along the outer surface, etc.). The fingers 416a are shown to be curved so that a first portion of the fingers 416a extends substantially parallel to an axially facing surface ofAtty. Dkt. No.: NEXC.002WO (125194-2505)the support panel 412a, and so that a second portion of the fingers 416a extends along the axial direction relative to the central axis of the first treatment assembly 410a. The fingers 416a also include a bent portion (e.g., a 35-degree bend, a 45-degree bend, a 90-degree bend, or any value between and including the foregoing values, etc.) extending from the first portion to the second portion and tangent with the first portion and the second portion. In alternative configurations, as the fingers 416a may be straight or linear as well. The fingers 416a may be oriented such that a convex portion of the fingers 416a are circumferentially aligned relative to a central axis of the support panel 412a such that the convex portion faces a direction of rotation of the support panel 412a when rotating.

[0135] The treatment elements 414a of the first treatment assembly 410a are each shown to include a single finger 416a. However, in other embodiments, the treatment elements 414a may be formed from multiple elements (e.g., fingers, etc.). In some embodiments, the treatment elements are formed from a base and multiple fingers extending from the base (e.g., a central portion, a central body, a cylindrical protrusion, etc.) and having a flower or clawlike appearance. In other embodiments, treatment elements with non-flower-like appearance may be utilized, as well, that still provides a user with a number of closely spaced pressurepoint elements that can be pressed and guided along a patient’s skin to cause fascia tissue to be released or perform a non-therapeutic function. In some embodiments, as shown, the finger members may be substantially the same length (e.g., less than 0.1 inch difference in length between finger length) such that the tips of the finger members are substantially coplaner and parallel to a support structure (in the case of a flat support structure) so that a pressure load applied to the skin and fascia tissue is substantially equally applied by each of the finger members.

[0136] The fourth treatment assembly 410d of FIG. 4D may include a brush treatment assembly having multiple treatment elements 414d that together form a brush. The bristles of the brush extend substantially normal to the support panel 412d and may all have approximately equal length. In other embodiments, the arrangement of the bristles for the brush may be different. The bristles of the brush may be made of any suitable material including nylon, polypropylene, silicone, horse hair, feather, or any other natural or synthetic filament material. The tips of the bristles may be flocked (split) or unflocked. The tips of the bristles may also be rounded, bulbous, flat, pointed, etc. The bristles may be soft and flexible for a comfortable and soothing treatment, or may be rigid and stiff for a more aggressive tissue treatment. In some embodiments, the bristles include both soft / flexible bristles and rigid / stiff bristles for a combined treatment. In other embodiments, a first brush of theAtty. Dkt. No.: NEXC.002WO (125194-2505)treatment device may have a first type of bristles and a second brush having a different type of bristles.

[0137] The fourth treatment assembly 410d of FIG. 4D may also include a light therapy system including a plurality of light emitting diode (LED) lights directed toward the skin to provide additional therapy to the fascia tissue. The LED lights or other light elements for the light therapy system may be disposed in the treatment device (e.g., coupled to the housing and facing the effector), along the surface of the support panel 412d, and / or within the support panel 412d. In such embodiments, the support panel 412d may be formed from a transparent or semi-transparent material (e.g., clear plastic, etc.) having high transmissivity to enable near complete transmission of light to the skin. The light therapy system may provide light in one or more of the following forms: Red light (625 nm), Blue light (415 nm), Red + Blue light (625 nm~415 nm), Infrared (760 nm). In other embodiments, the light therapy system may provide light at wavelengths of 640 nm, 880 nm, and 930 nm, which can increase cell proliferation and / or healing, boost production of collogen (to facilitate fascia remodeling). User input controls (e.g., the second switch described with reference to FIG.1A), such as knobs, buttons, or otherwise, may be accessible to a user from the treatment device to control operation of the LED lights and control circuitry.

[0138] It should be understood that the LED lights, bristles (e.g., brush elements, etc.), and fingers / finger members may be used together in various embodiments, including any embodiment of the treatment assembly described herein. For example, the treatment assembly may include brush elements and / or bristles disposed between adjacent ones of the fingers (e.g., between rows of fingers, etc.), or in any other location along the treatment assembly. In some embodiments, the treatment assembly also includes fingers and / or bristles extending radially outward from side surfaces of the support panel (e.g., side surfaces that face radially away from the central axis of the support panel, etc.). Similarly, the LED lights may be disposed at any location in which the light can be properly directed to a patient’s skin (i.e., is not blocked by another element of the treatment assembly). For example, the LED lights may be disposed at, or adjacent to, the tips of the treatment elements or along a periphery of the treatment device. The LED lights may be disposed on the housing and may be pointed at an angle outward from the housing, toward the treatment assembly, or in any other location, arrangement, and / or orientation so as to direct light onto the skin surface. The LED lights may be aimed in front of, to the side, or between the treatment elements so that the lights may be incident skin of a user prior to and / or after the treatment elements pass a region of skin of a user. In an embodiment, a motion sensor may sense when the device is inAtty. Dkt. No.: NEXC.002WO (125194-2505)use (e.g., moving back and forth) and cause the LED lights to automatically turn ON during motion, and cause the LED lights to automatically turn OFF when not in motion or not moving in a particular treatment motion (e.g., rotating, substantially linearly forward / backward or side-to-side, where substantially means that there may also be some rotational and / or vibrational movement during operation). One or more pressure sensors (e.g., between the treatment element(s) and bar) may also be utilized to determine when the device is in operation and cause the LED lights to turn ON and OFF. A timing circuit may be utilized to maintain the LED lights in the ON state for a minimum duration of time (e.g., 15 seconds). In an embodiment, circuitry may turn the LED lights ON and OFF in a particular pattern, such as lighting certain LED lights when moving in a first direction and other LED lights when moving in a second direction.

[0139] In some embodiments, the treatment assembly and / or the treatment device may also include other treatment elements and / or tissue stimulators. For example, the treatment device may include a soft tissue stimulation system configured to provide electrical current to the treatment area by placing a plurality of electrodes on the skin surface and providing electrical impulses via the electrodes to the skin and soft tissue (such as fascia tissue) below the skin’s surface. In some embodiments, the stimulation system employs circuitry and hardware elements that can execute traditional TENS (transcutaneous electrical nerve stimulation) and / or NMES (neuromuscular electrical stimulation) therapy. In such embodiments, at least one lead wire may be electrically coupled to the treatment device, the treatment assembly, and / or a separate device that is coupled to the treatment assembly, with a transcutaneous electrode at the distal end for delivering the electrical impulses to the patient. The transcutaneous electrode may adhere to the skin. The device may be configured to provide a pre-determined stimulation waveform having a pre-determined frequency (Hz), pulse width (ps), and amplitude (mA). Alternatively, the device may be configured to allow a user to modify one or more parameters of the stimulation waveform.

[0140] The electrodes may be positioned on various parts of the treatment device (such as on the treatment elements, the support panel, etc.) to be placed in direct contact with the skin for stimulation. In an embodiment, the treatment assembly, for example, may be configured with an accessible compartment that is configured to store batteries, control circuitry, electrode(s), wires, etc., thereby enabling the treatment to be self-contained within the treatment assembly. In other embodiments, electrode(s) form part of a treatment accessory that can be coupled to the treatment assembly and / or the housing. User input controls, such as knobs, buttons, or otherwise, may be accessible to a user to control operation of theAtty. Dkt. No.: NEXC.002WO (125194-2505)stimulation signals applied to a user from the electrodes controlled by the control circuitry. In operation, the user may remove the electrode(s) from the compartment and apply to him or herself. The electrodes, in an embodiment, may be attached to straps that may wrap around or be applied to a patient’s body, such as an arm or leg, so as to apply the TENS or NMES treatment before, during, or after fascia tissue treatment by the device with the treatment elements. As an example, the electrodes may be positioned to the sides of a pathway that the treatment elements are to be applied and electrical stimulation may occur before, during, or after treatment.

[0141] Referring to FIG. 4E, the fifth treatment assembly 410e, which may also be referred to as a fifth effector, may be configured to automatically adjust a position of at least one treatment element 414e (which may also be referred to as a sub-effector) responsive to forces applied to the at least one treatment element 414e. The fifth treatment assembly 410e may include a support panel 412e and multiple treatment elements 414e coupled to the support panel 412e.

[0142] As shown, the treatment elements 414e may be arranged in segments across the support panel 412e. At least one of the treatment elements 414e includes a treatment element panel 418 and a finger 416e that extends away from the treatment element panel 418. The treatment element panels 418 of the treatment elements 414e may be substantially planar panels that extend parallel to the support panel 412e. The treatment element panels 418 together may define an axially facing surface that substantially covers the support panel 412e.

[0143] In some embodiments, as shown, the treatment element panels 418 are pie-shaped slices or wedges that extend radially away from a central axis of the fifth treatment assembly 410e. The treatment element panels 418 may be substantially identical to one another and may have the same outer profile when viewed along the central axis of the fifth treatment assembly 410e. In the embodiment of FIG. 4E, the fifth treatment assembly 410e includes three treatment elements 414e, with each treatment element 414e extending from the central axis to an outer perimeter of the fifth treatment assembly 410e. In other embodiments, the number, size, shape, and / or arrangement of the treatment elements 414e may be different. For example, referring to FIG. 5, a treatment assembly 510 is shown that includes treatment elements 514 having treatment element panels 518 arranged as concentric rings that surround a central, circular shaped treatment panel (e.g., having a circular outer profile when viewed normal to a central axis of the treatment assembly 510). Each of the treatment elements 514 may include multiple fingers 516 disposed thereon and extending from the treatment elementAtty. Dkt. No.: NEXC.002WO (125194-2505)panel 518. The number and arrangement of fingers 516 may be different between the treatment element panels 518 and according to various embodiments.

[0144] In an embodiment, each of the treatment element panels 518 are configured to move along an axial direction (e.g., parallel to the central axis of the support panel) responsive to an applied axial force against the treatment element panels 518. In some embodiments, each of the treatment element panels 518 is pivotally engaged with the support panel so that the treatment element panels 518 may tilt toward the support panel (e.g., may rotate into a non-parallel orientation with respect to the support panel), and depending on where the axial force is applied along the treatment element panel 518.

[0145] In some embodiments, the treatment element panels 518 may be flexible in orientation so as to enable the treatment elements 514 to be adjusted in orientation (e.g., to enable manual reorientation of the treatment elements 514 into non-planar orientations) while a treatment is being performed (e.g., to better conform with body curvature along a patient’s shoulder(s) or arm(s)).

[0146] Referring to FIG. 6, a treatment assembly 610 is shown that includes circular treatment element panels 618 that are segmented into four or more pie shaped slices, such that each pie slice includes at least two concentric ring-shaped panels and a portion of a circular shaped center panel. The level of discretization and shape of the individual treatment element panels may be different in various embodiments.

[0147] The treatment elements are movably coupled to the support panel and are configured to move relative to one another and the support panel responsive to an applied force (e.g., an applied pressure against the treatment elements). Referring to FIG. 7, another treatment assembly 710 is shown that may have the same or a similar internal structure as the fifth treatment assembly 410e of FIG. 4E. The treatment assembly 710 may include a support panel 712 and multiple treatment elements 714 (which may also be referred to as subeffectors) that are movably coupled to the support panel 712. The treatment element panels 718 are spaced apart from the support panel 712 to define an interior cavity 720 therebetween. In an embodiment, a height of the interior cavity 720 between the treatment element panels 718 and the support panel 712 is approximately 1 inch. In other embodiments, the height of the interior cavity 720 may be different (e.g., 0.5 inches, 0.75 inches, 0.9 inches, 1.25 inches, or any value between and including any two of the foregoing values), and / or to any desired height to accommodate different treatment modalities. In at least one embodiment, the treatment assembly 710 may also include a side cover (e.g., seeAtty. Dkt. No.: NEXC.002WO (125194-2505)side panel 420 FIG. 4E) that extends from the support panel 712, along the outer perimeter of the support panel 712 to the outer perimeter of the treatment element panels 718. The side cover may be configured to circumscribe the interior cavity 720 and to prevent dirt and debris from entering the interior cavity 720. In some embodiments, the cover is configured to support an outer edge portion of at least one treatment element panel 718.

[0148] In some embodiments, the treatment elements 714 are resiliently biased away from the support panel 712. As shown in FIG. 7, the treatment assembly 710 may include one or more spring elements 722 that support the treatment elements 714 in a position away from the support panel 712. The spring elements 722 may be disposed within the interior cavity 720. The spring elements 722 may be engaged with the support panel 712 and respective ones of the treatment elements 714. In some embodiments, each treatment element panel 718 is supported by a single spring element 722. In other embodiments, at least one treatment element panel 718 may be supported by multiple spring elements 722.

[0149] The spring elements 722 may extend along the axial direction relative to the central axis of the treatment assembly 710 from the support panel 712 to respective ones of the treatment element panels 718. In some embodiments, and as shown, the spring elements 722 may be helical compression springs (e.g., compression springs, etc.). In other embodiments, another type of spring element 722 may be used. For example, the spring elements 722 may include at least one leaf spring, a cantilevered spring formed from an elongated strip of metallic material that extends from a perimeter edge of the treatment assembly 610, or another location along the treatment assembly 710. The spring elements 722 may be linear or non-linear springs. The spring elements 722 may be the same or different types of springs. The spring elements 722 may have any spring coefficient K and the spring coefficients K may be the same or different across the treatment assembly 710.

[0150] The spring elements 722 may be characterized by a linear spring constant so that a displacement of the treatment elements 714 is proportional to a force applied to the treatment elements 714 along the axial direction. In other embodiments, and depending on the application, the spring elements 722 may be characterized by a non-linear spring constant to provide rates of displacement that vary with the applied force at different axial positions of the treatment element panels 718 or portions thereof. In an embodiment, the spring elements 722 may be at an angle relative to the central axis of the treatment assembly 710 so as to be aligned with a rotational axis of the treatment element panels 718.Atty. Dkt. No.: NEXC.002WO (125194-2505)

[0151] In the embodiment of FIG. 7, the support panel 712 and / or at least one treatment element 714 may include a spring positioning element 724 that is engageable with the spring element 722 to support the spring element 722 in position between the support panel 712 and the treatment elements 714. For example, and as shown, the spring positioning element 724 may include a hollow cylindrical protrusion (e.g., a hollow tube, etc.) defining a recessed area that is configured to nestably receive the spring element 722 therein. The number and arrangement of spring elements 722 within the interior cavity 720 may be different in various embodiments, and depending on the desired forces resisting movement of the individual treatment elements 714. For example, in some embodiments, the spring elements 722 are spaced uniformly apart within the interior cavity 720. Such an arrangement can provide a more uniform distribution of forces across the treatment assembly 710. In other embodiments, greater numbers of the spring elements 722 may be located under certain ones of the treatment elements 714 or in certain areas of the interior cavity 720 (e.g., more spring elements 722 may be located adjacent to the cover and / or outer perimeter to increase the forces resisting movement of the treatment elements 714 adjacent to the outer perimeter, etc.).

[0152] In some embodiments, and as shown, the treatment assembly 710 includes a plurality of stops 726, which may include bumpers made from plastic or rubber, to limit displacement of the treatment elements 714 along the axial direction. In other embodiments, the treatment assembly 710 may be structured so that the treatment element panels can move freely across an entire height of the interior cavity 720. In some embodiments, the treatment assembly 710 may further include at least one retention element to limit displacement of the treatment element panels away from the support panel 712. For example, and referring to FIG. 7, the at least one retention element may include a cord (e.g., a cable, string, etc.) that extends between and connects the treatment element panel to the support panel 712. In other embodiments, the retention element may include a rod-in-tube or a tube-in-tube arrangement including a rod or tube of the treatment element panel that is nestably engaged with a hollow tube of the support panel 712 (or vice versa) and that limits a maximum displacement of the rod within the hollow tube. In yet other embodiments, the spring elements 722 may be sized to support the treatment element panels in a substantially parallel alignment with the support panel 712 in an uncompressed position of the spring elements 722.

[0153] In an embodiment, the treatment assembly 710 may include a barrier element 728, which may also be referred to as an attachment element, that is engaged with and extends between adjacent edges of the treatment element panels 718. The barrier element 728 may beAtty. Dkt. No.: NEXC.002WO (125194-2505)sealingly engaged with each of the treatment element panels 718 to thereby substantially prevent dirt, oils, and / or other contaminants from entering the interior cavity 720. In an embodiment, the barrier element 728 includes a rubber (e.g., silicone) or soft flexible plastic. The barrier element 728 may be over-molded onto the treatment element panels 718. In other embodiments, the barrier element 728 may be bonded to the treatment element panels 718 using an adhesive material. The barrier element 728 is a flexible, non-rigid material so as to allow relative movement (e.g., bending, flexing, etc.) between adjacent treatment element panels 718. The barrier element 728 may also be structured to enable the treatment element panels 718 to move toward and away from one another to better conform to a profile of a patient’s skin.

[0154] The design of the treatment assembly 710 may be different in various embodiments. For example, referring to FIG. 8, a treatment element assembly 810 is shown that includes a single, individual, treatment element panel 818 made from a flexible material, such as a polycarbonate sheet, a polypropylene sheet, or another flexible plastic sheet. The treatment element panel 818 is supported by multiple spring elements 822 that extend between a support panel 812 and the treatment element panel 818. The position and / or number of spring elements 822 may differ in various embodiments. Using a single flexible treatment element panel 818 can, in some instances, provide a more uniform contour (e.g., a continuous curvature) across the treatment element panel 818 responsive to an applied axial force.

[0155] Referring to FIG. 9, a treatment assembly 904 is shown that includes a treatment element panel 918 that is engaged with and fixedly coupled to a support panel instead of being spaced apart from the support panel. The treatment element panel 918 may be made from a soft, compressible material, such as rubber, foam, or another non-rigid and compliant material. The treatment element panel 918 is configured to deform under an applied pressure to one or more fingers across the surface of the treatment element panel 918. In some embodiments, the treatment element panel 918 is made from a memory foam (e.g., polyurethane foam, etc.) having a low recovery rate (e.g., a slow recovery rate) so as to at least partially maintain a shape resulting from application of pressure to the treatment element panel 918 or portions thereof.

[0156] Referring to FIGS. 10-12, various additional illustrative treatment assembly designs that may be used with the treatment head 102 of FIGS. 1A-1D are shown. In the embodiment of FIG. 10, the treatment head 102 of FIGS. 1A-1D is coupled to the second treatment assembly 410b of FIG. 4B. In the embodiment of FIG. 11, the treatment head 102Atty. Dkt. No.: NEXC.002WO (125194-2505)is coupled to the fifth treatment assembly 410e of FIG. 4B. In the embodiment of FIG. 12, the treatment head 102 is coupled to the fourth treatment assembly 410d of FIG. 4D.

[0158] FIG. 14 shows the treatment head 202 of FIG. 2 coupled to the third treatment assembly 410c of FIG. 4C. FIG. 15 shows the treatment head 202 of FIG. 2 coupled to the second treatment assembly 410b of FIG. 4B. FIG. 16 shows the treatment head 202 of FIG.2 coupled to the fifth treatment assembly 410e of FIG. 4E. FIG. 17 shows the treatment head 202 of FIG. 2 coupled to the fourth treatment assembly 410d of FIG. 4D.

[0159] FIGS. 18A-18B show perspective and side views, respectively of the treatment head 202 of FIG. 2 coupled to a user interface element 804 that has a different aesthetic appearance from the user interface element 204 of FIG. 2.

[0160] FIGS. 19A-19H show various views of an illustrative mounting system and drive system, shown as mounting system 900, for a tissue treatment device (e.g., a treatment head) that is configured to connect and power movement of, respectively, a tissue treatment assembly 904 (which may also be referred to as a tissue treatment effector) for the tissue treatment device (e.g., an effector that is configured to engage a patient’s tissue).

[0161] The mounting system 900 includes an actuator 902 (e.g., an electric motor) that is configured to drive rotation of the treatment assembly 904. In the embodiment of FIGS.19A-19H, the drive system may also include a transmission 906 (e.g., a gear box, a gear assembly) that is configured to transfer power from the actuator 902 to the treatment assembly 904, such as through a connecting rod that extends between the transmission and the treatment assembly 904.

[0162] The mounting system 900 may be configured to connect the treatment assembly 904 to a drive system of the tissue treatment device (e.g., the treatment head). In some embodiments, and as shown, the mounting system 900 may include a mounting plate 908 (which may also be referred to as a base plate) that is configured to detachably couple the treatment assembly 904 to the tissue treatment device.

[0163] Referring to FIG. 19E, the mounting plate 908 includes a plurality of connector elements 910, which may include or form part of a quick-connect mechanism to removably couple the treatment assembly 904 to the actuator 902. In some embodiments, and as shown, the connector elements 910 include pins (e.g., a mushroom head pin connector), studs, orAtty. Dkt. No.: NEXC.002WO (125194-2505)another type of connector that is configured to engage the treatment assembly 904 to prevent relative movement between the treatment assembly 904 and the mounting plate 908. In some embodiments, and as shown (see FIGS. 19C-19D), the connector elements 910 include pins having a mushroom head profile, a button head profile, or another shape having a greater outer diameter than a pin body of the connector element 910. As shown in FIG. 19C, the connector elements 910 also include biasing elements 912 (e.g., springs) that bias the heads of the pins toward the mounting plate 908, while allowing freedom of axial movement away from the mounting plate 908. Such an arrangement can also improve the holding force between the mounting plate 908 and the treatment assembly 904 (e.g., a base member and / or a base panel of the treatment assembly 904).

[0164] In some embodiments, and as shown in FIG. 19E, the connector elements 910 (e.g., the pins, etc.) are disposed at an intermediate radial position along the mounting plate 908 that is spaced radially apart from a central axis 914 of the mounting plate 908. Such an arrangement can reduce the force required at the individual connector elements 910 to satisfy torque requirements, and can also improve durability by sharing the load across multiple connection points. In other embodiments, the connector elements 910 may be located proximate to or along an outer perimeter of the mounting plate 908, which can further reduce load and improve torque distribution across the mounting plate 908. In some embodiments, and as shown, the connector elements 910 are spaced apart from one another along a circumferential direction relative to a rotational axis of the mounting plate 988 (e.g., the rotational axis and / or the central axis of the actuator 902.

[0165] In some embodiments, the pins may be configured to engage with openings 916 (e.g., slots) defined by a base member and / or base panel of the treatment assembly 904 (e.g., a backing plate of the effector (e.g., an effector plate, an effector panel, etc.), in a twist lock arrangement. In the embodiment of FIG. 19E, the openings 916 are slots that extend along a circumferential direction relative to the central axis 914. The slots have a reduced opening dimension at a distal end thereof (e.g., a second circumferential end) relative to a proximal end (e.g., a first circumferential end) at which the pins are inserted into the slots. In some embodiments, the mounting system 900 may include another type of quick-connect coupling, including a bayonet fastener, or another type of rotary quick connector. In other embodiments, the mounting system 900 may include another type of fastening mechanism to secure the treatment assembly 904 to the actuator, such as by a threaded connection. It should be understood that alternative configurations, such as interlocking threads on the mountingAtty. Dkt. No.: NEXC.002WO (125194-2505)plate and treatment assembly 904, may be utilized for removably connecting the treatment assembly 904 and mounting plate 908.

[0166] Referring to FIG. 20, an actuator 1002 of a drive system 1000 is shown that may be the same as or similar to the actuator 1002 used in the embodiment of FIGS. 19A-19H.The drive system 1000 (e.g., the actuator 1002) includes a stator 1004 and a rotor 1006 arranged circumferentially around the stator 1004 and circumscribing the stator 1004. Such an arrangement (e.g., the rotor 1006 having a greater radial dimension than the stator 1004) can shift rotational forces to a greater radial position, which can increase torque for the same amount of applied force to the rotor 1006. Such an arrangement can greatly increase the performance of the actuator 1002. The rotor 1006 may be a permanent magnet rotor having permanent magnets arrangement circumferentially around the windings of the stator 1004. In some embodiments, and as shown, the rotor 1006 is rotationally coupled to the stator 1004 by a central shaft that extends through and is coupled to both the rotor 1006 and the stator 1004.In some embodiments, the shaft may be coupled to the mounting plate and may be configured to drive rotation of the mounting plate.

[0167] In some embodiments, the drive system and the mounting system may be at least partially integrally formed with one another (e.g., the mounting system is integrated with at least a portion of the actuator, etc.). For example, an actuator of the drive system may include a direct drive motor that is configured to directly connect the actuator to the tissue treatment assembly without an intervening transmission. The connection may be a removable or permanent attachment. In such embodiments, the drive system the rotor may be directly coupled to and support the mounting plate thereon (i.e., the mounting plate may directly attach to the rotor, such as through pins connected to an end panel of the rotor, such as an end panel 1008, to an intermediate radial position or an outer radial position along the end panel 1008, etc.). The mounting plate may be configured to support the connector elements proximate to an outer perimeter of the mounting plate, such that the rotor directly powers rotation of the effector, without an intervening gear set or connecting rod. Such an arrangement can reduce noise, increase operational efficiency, and improve the overall structural durability of the drive and mounting system. In such a direct drive system, increased rotation speed through use of gears may be unavailable, but reduction in weight, gear wear, noise, and heat generation may be reduced.

In some embodiments, operation 1106 includes coupling the tissue treatment assembly to a connecting element that is rotatably coupled to the actuator and that is spaced apart from a rotational axis of the actuator such that rotational movement of the tissue treatment assembly is driven by the actuator. In some embodiments, operation 1106 includes coupling the tissue treatment assembly to a connecting element disposed proximate to an outer perimeter of a mounting plate of the mounting and drive system. In some embodiments, operation 1106 includes coupling the tissue treatment assembly to a connecting element at an intermediate position between the rotational axis and the outer perimeter of the mounting plate (e.g., via a quick-connect coupling, via a threaded connection, or any other connection mechanism described herein).

[0174] In some embodiments, operation 1106 includes connecting the treatment assembly to the treatment head in a first mode of operation, and the method 1100 further includes coupling a second treatment assembly to the treatment head that is different from the first treatment head in a second mode of operation.

It should be understood that the therapy device may be used for increasing overall myo-fascial fitness to loosen fascia tissue that is constrained, improve health and / or beauty purposes (e.g., provide a satisfactory feeling to a user and / or alter the appearance of cellulite and skin smoothness). Moreover, usage of the fascia tissue fitness device may open, loosen, restore, and / or revitalize fascia tissue of men and women, young and old.Atty. Dkt. No.: NEXC.002WO (125194-2505)
