[0027] (Detailed explanation) 1A-D , an anchoring device 100 for reversibly retaining at least one of a catheter and (for example) a needle within tissue is provided. The device 100 includes a cylinder or cylinder-like structure 106 including a wall 108, an outer surface 110, and one or more claws 112. Each claw 112 can include at least a portion thereof that is flexibly integral with and / or flexibly secured to at least one of the outer surface 110 and the wall 108, and can be configured to protrude away from the surface 110 of the cylinder 106 when in the deployed state. In the undeployed state, each claw 112 can be configured to coil or otherwise fold in response to rotation of the cylinder 106 in a first direction 114 such that at least one of each claw resides directly adjacent to the outer surface 110. In some embodiments, one or more of the claws 112 (preferably all of the claws) are received by recesses or openings 116 in at least one of the surface 110 of the cylinder 106 and the wall 108 of the cylinder 106 upon folding / wrapping.
[0028] As shown in the figures, in some embodiments, multiple claws 112 may be provided and arranged around the circumference of the cylinder 106 and may be evenly spaced around the circumference of the cylinder 106.
[0029] 2 illustrates an example of a catheter 154, 162 of a pain management device 150 configured to deliver at least one of electrical pulses and fluid (e.g., medication) to which an anchoring device 100 can be used / secured. The catheters 154, 162 (similar pain management device embodiments are also disclosed in WO2022221452A1, incorporated herein by reference) can include a proximal connector 152 (which can be connected to a fluid source), a second connector 156 and associated tubing 158 (which can accommodate an electrical connector and a wire / lead, respectively, for connecting an external electrical stimulation device to the device 150), and a third connector 158, which can be a Luer lock. A pulse generator 160 is connected to the catheters / tubing 154 and / or 158 via the Luer lock and to the distal tubing / catheter 162 to deliver fluid and / or electrical stimulation (e.g., via electrodes 164) to tissue into which the device 150 is inserted. In some embodiments, the anchoring device 100 is anchored to the portion of the distal catheter 162 that is inserted into tissue to keep at least the distal catheter 162 in place. The anchoring device 100 of the present disclosure can be anchored at a point along the distal catheter, according to some embodiments. Specifically, the anchoring device can be anchored to the portion of the catheter that is disposed within the tissue at any point therein.
[0030] The surface area of each claw is approximately 0.1 to 100 mm 2, which has been found to assist in retaining at least one of the catheters (and, in some embodiments, the needle) within the tissue. Similarly, each prong may include a height of 0.5 mm to 10 mm relative to the surface 110 of the cylinder 106 and at least one edge configured to interact with tissue to hold at least the distal end of the catheter 102 and / or needle 104 within the tissue in response to an axial force being placed on the catheter 102 and / or needle 104 proximally. Each prong, in some embodiments, may include at least one of a triangular shape (as shown), a curved shape, a "W" shape, an "M" shape, and a hook shape (e.g., a "fishhook") configured to perform the task of securing the catheter in place. Such shapes include one or more sharp or barbed portions that may be temporarily at least slightly embedded in the tissue and hold the catheter in place for the period of time required to perform the medical procedure or aid.
[0031] In some embodiments, as initially described above, one or more of the claws are configured as or include at least one barb 118 portion configured to interact with tissue to retain the catheter and / or needle within the tissue. Moreover, in some embodiments, each claw 112 can be configured as or include a smooth portion or curve-like structure configured to interact with tissue to retain the catheter 102 and / or needle 104 within the tissue. The geometry of a claw with smooth edges can unexpectedly provide a sufficient retention force to keep the catheter in place within the tissue. The claws can include different geometric shapes, including semicircular, semi-elliptical, triangular, square, rectangular, and / or polygonal shapes with different numbers of sides.
[0032] In some embodiments, one or more of the claws 112 can be configured as a propeller-like structure in the deployed state (as shown), and the propeller-like structure can be configured with a pitch of 1 degree to 90 degrees (and any range therebetween) relative to the axis of the cylinder 106.
[0033] The one or more claws may have a number of 1 to 1,000 (or more), preferably less than 100, more preferably less than 50, and most preferably 1 to 20, 1 to 19, 1 to 18, 1 to 17, 1 to 16, 1 to 15, 1 to 14, 1 to 13, 1 to 12, 1 to 11, 1 to 10, 1 to 9, 1 to 8, 1 to 7, 1 to 6, 1 to 5, 1 to 4, 1 to 3, 1 to 2, 2 to 20, 2 to 19, 2 to 18, 2 to 17, 2 to 16, 2 to 15, 2 to 14, 2 to 13, 2 to 12, 2 to 11, 2 to 10, 2 to 9, 2 to 8, 2 to 7, 2 to 6, 2 to 5, 2 to 4, 2 to 3, 3 to 20, 3 to 19, 3 to 18 , 3-17, 3-16, 3-15, 3-14, 3-13, 3-12, 3-11, 3-10, 3-9, 3-8, 3-7, 3-6, 3-5, 3-4, 4-20, 4-19, 4-18, 4-17, 4-16, 4-15, 4-14, 4-13, 4-12, 4-11, 4-10, 4-9, 4 ~8, 4~7, 4~6, 4~5, 5~20, 5~19, 5~18, 5~17, 5~16, 5~15, 5~14, 5~13, 5~12, 5~11, 5~10, 5~9, 5~8, 5~7, 5~6, 6~20, 6~19, 6~18, 6~17, 6~16, 6~15, 6~14, 6~13 , 6-12, 6-11, 6-10, 6-9, 6-8, 6-7, 7-20, 7-19, 7-18, 7-17, 7-16, 7-15, 7-14, 7-13, 7-12, 7-11, 7-10, 7-9, 7-8, 8-20, 8-19, 8-18, 8-17, 8-16, 8-15, 8-1 4, 8-13, 8-12, 8-11, 8-10, 8-9, 9-20, 9-19, 9-18, 9-17, 9-16, 9-15, 9-14, 9-13, 9-12, 9-11, 9-10, 10-20, 10-19, 10-18, 10-17, 10-16, 10-15, 10-14, 10 ~13, 10~12, 10~11, 11~20, 11~19, 11~18, 11~17, 11~16, 11~15, 11~14, 11~13, 11~12, 12~20, 12~19, 12~18, 12~17, 12~16, 12~15, 12~14, 12~13, 13~20, 1 3-19, 13-18, 13-17, 13-16, 13-15, 13-14, 14-20, 14-19, 14-18, 14-17, 14-16, 14-15, 15-20, 15-19, 15-18, 15-17, 15-16, 16-20, 16-19, 16-18, 16-17,These may include 17-20, 17-19, 17-18, 18-20, 18-19, and 19-20.
[0034] The plurality of claws 112 may be arranged in one or more planes 113 that lie perpendicular to the axis 120 of the cylinder 106. The one or more planes may preferably be fewer than 10 planes, most preferably 1-10, 1-9, 1-8, 1-7, 1-6, 1-5, 1-4, 1-3, 1-2, 2-10, 2-9, 2-8, 2-7, 2-6, 2-5, 2-4, 2-3, 3-10, 3-9, 3-8, 3-7, 3-6, 3-5, 3-4, 4-10, 4-9, 4-8, 4-7, 4-6, 4-5, 5-10, 5-9, 5-8, 5-7, 5-6, 6-10, 6-9, 6-8, 6-7, 7-10, 7-9, 7-8, 8-10, 8-9, and 9-10. Such planes can be exactly 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10, according to some embodiments. In some embodiments, the planes of the distributed claws (e.g., located around the circumference of the cylinder) can be at an acute or oblique angle to the axis 120 of the cylinder. The angle as well as the number of planes on which the claws are arranged can be calculated to provide different amounts of retention force.
[0035] In some embodiments, the barbs 118 of one set of claws arranged in one plane reside in opposite directions, and then the barbs 118 of another set of claws (e.g., an adjacent set of claws) may be arranged in a second plane such that when projecting outward, the two planes of the claws limit movement of the distal catheter 162 in both distal and proximal directions. In such embodiments, rotation of the catheter device in a first direction allows the barbs to project outward, and rotation of the catheter device in a second direction opposite the first (e.g., counterclockwise as opposed to clockwise) allows the claws to fold or advance (e.g., downward) so that they no longer engage or do not sufficiently engage tissue, allowing removal of the catheter device.
[0036] In some embodiments, device 150 can include one or more electrodes 164 , and device 150 can also include (in some embodiments) an electrical pulse generator 160 .

The liner extrusion can be a 55D Pebax® liner covering the jacket extrusion, which can be, for example, a 55D Pebax® jacket. A cylinder (with prongs) can be mounted on an additional liner, which can be a 55D Pebax® liner. The catheter 150 can include a first distal electrode and a second, more distal one of the electrodes 164. The conductor wire 158 can be used, for example, to power the electrode.
[0038] In some embodiments, device 100 is spaced from the distal tip / end of the catheter (together with the assembly) a predetermined distance that can range from 10 mm to 100 mm in some embodiments. In some embodiments, the distance is preferably 20 to 40 mm, in some embodiments, 25 to 35 mm, and in still further embodiments, about 30 mm. In some embodiments, electrodes contained within the distal portion of the catheter are positioned distal to the positioning device.
[0039] In some embodiments, a method is provided for retaining at least one of the catheter 154, 162 and needle within tissue. In some such embodiments, the method comprises any of the embodiments described above, i.e., the catheters 154, 162, the cylinder 106, and, optionally, the needle (in some embodiments, the needle is first inserted into the proximal end of the catheter 154 and directed proximally through the catheter 162; thus, in some embodiments, at least the tip of the needle can protrude outward from the end of the catheter 162) form an assembly; the needle can be removably secured to at least one of the catheters 154, 162 and the cylinder 106; the needle may include a tip that can be electrically charged (e.g., in some embodiments, may be part of the electrode 164); and The catheters 154, 162 may include one or more electrodes 164 for applying electrical current to tissue. providing a mooring device or system according to

The coating serves to insulate the needle so that when an electric current is applied to the proximal / tip end of the needle, the tip becomes electrically charged. In particular, insulation (not shown) can be included that is configured to electrically isolate the needle from the electrodes 164 of the device 150 (if included) when inserted into the catheters 154, 162. The needle (or assembly with the catheter) can be connected to an external neurostimulator (not shown), which is connected via 156.
[0041] The method may also include one and / or more of sterilizing a surface of tissue at the insertion site, anesthetizing the surface at the insertion site with a local anesthetic, and, optionally, inserting the assembly through the surface of the insertion site toward the target nerve under ultrasound imaging guidance. At least one of an ultrasound image produced by ultrasound imaging guidance and (in some embodiments) eliciting an appropriate muscle contraction of a muscle proximate to the target nerve via the charged tip of the needle is configured to confirm that the tip of the needle is adjacent to the target nerve.
[0042] The method may further include the steps of unlocking or otherwise unlocking the needle from the device 150, removing the needle from the tissue, rotating the cylinder 106 in a first direction so that one or more claws 112 of the anchoring device 100 deploy within the tissue, and rotating the cylinder 106 in a second direction opposite the first direction so that the one or more claws 112 of the anchoring device 100 are wrapped or otherwise folded so that they are directly adjacent to the outer surface of the cylinder 106 and, optionally, received by a recess or opening 116 in at least one of the surface 110 of the cylinder and the wall 108 of the cylinder 106.

[0047] (General considerations) While various inventive embodiments have been described and illustrated herein, those skilled in the art will readily envision various other means and / or structures for performing the functions and / or obtaining one or more of the results and / or advantages described herein, and each such variation and / or modification is deemed to be within the scope of the inventive embodiments described herein. More generally, those skilled in the art will readily appreciate that any parameters, dimensions, materials, and configurations described herein are intended to be examples, and that the actual parameters, dimensions, materials, and / or configurations will depend on the specific application or applications in which the inventive teachings disclosed herein are used. Those skilled in the art will recognize, or be able to ascertain using no more than routine experimentation, many equivalents to the specific inventive embodiments described herein. Accordingly, it should be understood that the foregoing embodiments are presented by way of example only, and that, within the scope of the claims supported by this disclosure and their equivalents, inventive embodiments may be practiced otherwise than as specifically described and claimed. The inventive embodiments of the present disclosure are also directed to each individual feature, system, article, material, kit, and / or method described herein. Additionally, any combination of two or more such features, systems, articles, materials, kits, and / or methods is within the inventive scope of the present disclosure, provided that such features, systems, articles, materials, kits, and / or methods are not mutually inconsistent.
[0048] The embodiments disclosed herein may also be combined with one or more features and complete systems, devices, and / or methods to yield still other embodiments and inventions. Also, some embodiments may be distinguishable from the prior art by specifically lacking one and / or another feature disclosed in a particular prior art reference, i.e., the claims to such embodiments are distinguishable from the prior art by including one or more negative limitations.
[0049] Also, various inventive concepts may be embodied as one or more methods. The acts performed as part of a method may be ordered in any suitable way. Thus, embodiments may be organized in which acts are performed in an order different from that illustrated, which may include performing some acts simultaneously.
[0050] The indefinite articles "a" and "an," as used herein in the specification and in the claims, should be understood to mean "at least one," unless expressly indicated otherwise. The terms "can" and "may" are used interchangeably in this disclosure to indicate that an element, component, structure, feature, functionality, purpose, advantage, operation, step, process, apparatus, system, device, result, or definite description reference has the ability to be used in, be included in, or produced by, or otherwise express the proposition set forth in the description in which the term is used (or referred to) with respect to a particular embodiment.
[0051] The term "and / or," as used herein in the specification and in the claims, should be understood to mean "either or both" of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Multiple elements listed with "and / or" should also be construed in the same manner, i.e., as "one or more" of the elements so conjoined. Other elements other than the elements specifically identified by the "and / or" clause may optionally be present, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to "A and / or B," when used in conjunction with open language such as "comprising," can, in one embodiment, refer to "A only" (optionally including elements other than B), in another embodiment to "B only" (optionally including elements other than A), and in yet another embodiment to "both A and B" (optionally including other elements), etc.
[0052] As used herein in the specification and in the claims, "or" should be understood to have the same meaning as "and / or" as defined above. For example, when separating items in a list, "or" or "and / or" shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also as including more than one of several elements or lists of elements, optionally including additional, unlisted items. Only terms clearly indicated to the contrary, such as "only one of," or "exactly one of," or, when used in the claims, "consisting of," will refer to the inclusion of exactly one element of several elements or lists of elements. In general, the term "or" as used herein, when preceded by terms of exclusivity such as "either," "one of," "only one of," or "exactly one of," shall be construed as indicating only exclusive alternatives (i.e., "one or the other but not both"). "Consisting essentially of," when used in the claims, shall have its ordinary meaning as used in the field of patent law.
[0053] As used herein within the specification and claims, the phrase "at least one," referring to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but does not necessarily include at least one of each and every element specifically listed in the list of elements, and does not exclude any combinations of elements in the list of elements. This definition also allows for the optional presence of elements other than those specifically identified in the list of elements to which the phrase "at least one" refers, whether related or unrelated to those specifically identified elements. Thus, as a non-limiting example, "at least one of A and B" (or, equivalently, "at least one of A or B" or, equivalently, "at least one of A and / or B") can, in one embodiment, be "at least one, optionally including more than one, A, with no B present" (optionally including elements other than B), in another embodiment, "at least one, optionally including more than one, B, with no A present" (optionally including elements other than A), in yet another embodiment, "at least one, optionally including more than one, A" and "at least one, optionally including more than one, B (optionally, at least one B, including more than one)" (optionally, including other elements), etc.
[0054] In the claims and in the above specification, all transitional phrases such as "comprising," "including," "carrying," "having," "containing," "involving," "holding," "composed of," and the like, are to be understood to be open-ended, i.e., meaning "including but not limited to." Only the transitional phrases "consisting of" and "consisting essentially of" shall be closed or semi-closed transitional phrases, respectively, as set forth in the U.S. Patent Office Manual of Patent Examining Procedures, Section 2111.03.
