FDBR Ref.: 473893.001217BRACE DEVICES, SYSTEMS, AND METHODS CROSS REFERENCE TO RELATED APPLICATION

[0001] The present application claims the benefit of and priority to, under 35 U.S.C. § 119(e), U.S. Provisional Application Ser. No. 63 / 743,066, filed on January 8, 2025, which is hereby incorporated herein by reference in its entirety for all that it teaches and for all purposes.TECHNICAL FIELD

[0002] The present disclosure relates to devices and methods for supporting a limb or limbs of a user when worn. More specifically, the present disclosure relates to devices, systems, and methods for supporting a knee of a user when worn.BACKGROUND

[0003] Devices for supporting or stabilizing the limb or limbs of a wearer may be worn by a user for everyday use and / or for use when engaging in physical activity. Injuries to a limb or limbs are common and may affect a user’s physical ability and / or athletic performance. For certain users it may be beneficial to use an artificial structure to support a limb that has been weakened or injured. Certain rigid or flexible structures may be worn through the day and / or when engaging in physical activity to provide structural support, or prevent injury. In certain instances they may assist a wearer’s movement, reduce weight bearing forces, or provide easier movement capability to a wearer.

[0004] For example, an athletic sleeve may be worn around a wearer’s limb to provide compression to the limb. An athletic sleeve may also be worn around a wearer’s joint such as a knee, wrist, ankle, or elbow to provide lateral or torsional support to the joint and / or to hold the joint in alignment. In some cases, an athletic sleeve may hold snugly to a joint such as a knee or elbow and improve performance while the wearer is engaged in physical activity. However, in some cases, an athletic sleeve may not provide adequate support to a wearer who has-1- DMSJJS.375277331.1FDBR Ref.: 473893.001217suffered an injury or may not provide targeted support to a wearer whose joint may require support in a specific location.

[0005] Certain support structures for the leg or knee of a user, such as sleeves, straps, or braces, are available and may provide certain advantages, such as weight bearing capabilities. However, such weight bearing capabilities are typically unchangeable for individual support structures, rendering them less effective for wearers with different training requirements, rehabilitation requirements, and / or preferences.SUMMARY

[0093] Various aspects of the present disclosure relate to brace systems that may be worn to protect and / or support a wearer’s limb, including a joint, for example a wearer’s knee. In some embodiments, knee brace systems may be used by a wearer who has suffered a meniscus tear, a patella injury, or has an unstable ligament, or an injury affecting lateral or torsional stability. In certain embodiments, knee brace systems include weight bearing capabilities, and such capabilities are changeable to accommodate different or varying training requirements, rehabilitation requirements, and wearer preferences.

[0094] FIGS. 1 and 2 illustrate a brace system 100, according to an embodiment of the present disclosure. The brace system 100 generally includes a support member 102 that is configured to receive a limb of a wearer, a first or lateral hinge assembly 104 (FIG. 1) coupled to the support member 102, and a second or medial hinge assembly 106 (FIG. 2) coupled to the support member 102. The first hinge assembly 104 and the second hinge assembly 106 are biased toward relatively straight configurations, which causes the first hinge assembly 104 and the second hinge assembly 106 to apply forces to the support member 102 that urge the limb of the wearer in an extension direction. If worn on the leg of the wearer, for example, the first hinge assembly 104 and the second hinge assembly 106 thereby facilitate supporting the weight of the wearer.

[0095] Illustratively, the support member 102 includes a generally tubular or cylindrical sleeve 108 having a first side 110 (FIG. 1 ) and a second side 112 (FIG.2), an inner surface (not shown), and an outer surface 114. The sleeve 108 also has a first or upper end 116 defining a first opening 118 and a second or lower end 120 defining a second opening 122. The inner diameter of the sleeve 108 may vary between the first end 116 and the second end 120. For example, the inner diameter of the sleeve 108 proximate the first end 116 may be sized to receive a portion of the upper leg of a user, such as a thigh. The inner diameter of the sleeve 108 proximate the second end 120 may be sized to receive the lower leg of a user, such as a calf or shin.

[0096] In various embodiments, the support member 102 may include one or more straps, illustratively a first or upper strap 124 and a second or lower strap 126, that facilitate fitting and securing the brace system 100 to the leg of the-12- DMSJJS.375277331.1FDBR Ref.: 473893.001217wearer. In various embodiments, the sleeve 108 may be constructed to be elastic and pliable and thereby fit snugly and provide compression to a user’s leg when worn, and further to flex and move with the user’s leg when the user runs, jumps or engages in other physical activity while maintaining the aforementioned snug fit at a suitable position on the leg. In various embodiments, the sleeve 108 may operate to wick sweat or other fluids away from a user’s leg when worn. In various embodiments, the sleeve 108 may also be configured to have odor absorbing or odor prevention and / or anti-bacterial properties. In some embodiments, the sleeve 108 may have a suitable contour or shape to fit either a user’s left leg or right leg. In some embodiments, the sleeve 108 may be a universal sleeve or interchangeable, that is, the sleeve 108 may be configured to be worn on either a user’s left leg or right leg.

[0097] The sleeve 108 may be formed using any conventional or later-developed fabrication techniques. In various embodiments, for example, the sleeve 108 may comprise a woven or knit fabric, or may be constructed using any other technique suitable for forming flexible fabric materials.

[0098] The material(s) used to form the sleeve 108 can be chosen from any natural or synthetic classes of materials that provide appropriate flexibility, resiliency and manufacturability. In various embodiments, the sleeve 108 may be formed from synthetic elastic materials such as spandex, a polyester-polyurethane copolymer (commonly sold under the brand name Lycra®), or other comparable elastic material. In some embodiments, all or part of the sleeve 108 can include synthetic rubbers such as neoprene. In certain embodiments, a material that provides breathability, ventilation, and / or moisture wicking capability may be used. In some embodiments, the sleeve 108 may include a knit nylon or polyester material. In certain embodiments, the sleeve 108 may include a perforated material. In various embodiments, a plurality of different materials is used to construct the sleeve 108.

[0099] In some embodiments, the support member 102 may have different arrangements and / or constructions. For example, the support member 102 may include multiple sleeves, particularly a first or upper sleeve and a second or lower sleeve, that includes gaps therebetween and are only coupled by the hinge assemblies 104, 106. As another example, the sleeve 108 may include an-13- DMSJJS.375277331.1FDBR Ref.: 473893.001217aperture and / or buttress for receiving and / or supporting the patella of the wearer. As yet another example, the support member 102 may include an anterior or posterior opening that is selectively openable to receive the leg of the wearer and closeable around the leg of the wearer.

[0100] With further reference to FIGS. 1 and 2, the support member 102 includes one or more couplers for coupling to the first hinge assembly 104 and the second hinge assembly 106. In some embodiments and as illustrated, the couplers are pockets, more specifically four pockets that receive the first hinge assembly 104 and the second hinge assembly 106. The first side 110 (FIG. 1 ) of the support member 102 includes a first or upper lateral pocket 128 and a second or lower lateral pocket 130 that partially receive the first hinge assembly 104. The first lateral pocket 128 includes a first lateral opening 132 that generally faces in an inferior direction D1 and through which the first hinge assembly 104 extends. The second lateral pocket 130 includes a second lateral opening 134 that generally faces in a superior direction D2 and through which the first hinge assembly 104 extends. Similarly, the second side 112 (FIG. 2) of the support member 102 includes a first or upper medial pocket 136 and a second or lower medial pocket 138 that partially receive the second hinge assembly 106. The first medial pocket 136 includes a first medial opening 140 that generally faces in the inferior direction D1 and through which the second hinge assembly 106 extends. The second medial pocket 138 includes a second medial opening 142 that generally faces in the superior direction D2 and through which the second hinge assembly 106 extends.

[0101] With brief additional reference to FIGS. 1 and 2, the first hinge assembly 104 (FIG. 1) generally includes a first or lateral spring hinge member 144 and a first or lateral tension member 146, and the second hinge assembly 106 (FIG. 2) generally includes a second or medial spring hinge member 148 and a second or medial tension member 150. The first spring hinge member 144 and the second spring hinge member 148 carry bending loads upon flexion of the limb of the wearer, and the lateral tension member 146 and the medial tension member 150 carry tensile loads upon flexion of the limb of the wearer. In addition, the lateral tension member 146 and the medial tension member 150 are detachable and replaceable with tension members with different deformation-14- DMS_US.375277331.1FDBR Ref.: 473893.001217resistance characteristics (provided by different dimensions (for example, unloaded length, cross section, or the like) or material properties (for example, elastic modulus)) to provide the system 100 with different load carrying characteristics (for example, depending on a wearer’s training requirements, rehabilitation requirements, and / or preferences). These aspects and additional features of the first hinge assembly 104 and the second hinge assembly 106 are described below.

[0102] FIGS. 3 and 4 illustrate the first hinge assembly 104 separate from the support member 102 (shown elsewhere). Although the second hinge assembly 106 is not illustrated separate from the support member 102, it is understood that the first hinge assembly 104 may have the same or similar features to the first hinge assembly 104.

[0103] As described above, the first hinge assembly 104 includes the first spring hinge member 144 and the lateral tension member 146. The first spring hinge member 144 includes an upper base 152, a lower base 154, and an intermediate serpentine spring element 156 that couples the upper base 152 to the lower base 154. The first spring hinge member 144 may be constructed of various relatively stiff but resilient materials or composites, such as polymers. The first spring hinge member 144 may be a monolithic component, or the features of the spring hinge member 144, such as the upper base 152, the lower base 154, and the serpentine spring element 156, may be separate components that are joined together.

[0104] With continued reference to FIGS. 3 and 4, the upper base 152 and the lower base 154 are received in the upper lateral pocket 128 and the lower lateral pocket 130 (both shown elsewhere), respectively, of the support member 102. The upper base 152 and the lower base 154 illustratively include relatively flat, trapezoid-like shapes. However, the upper base 152 and the lower base 154 may alternatively have other relatively shapes that are generally inflexible in the plane of the spring hinge member 144 (that is, the plane of the page in FIG. 4).

[0105] The serpentine spring element 156 is generally flexible in the plane of the spring hinge member 144. To facilitate this flexibility, the serpentine spring element 156 includes a plurality of partial coils, and adjacent partial coils extend in opposite directions. Stated another way, the serpentine spring element 156-15- DMSJJS.375277331.1FDBR Ref.: 473893.001217includes a plurality of anterior-facing partial coils 158, or coils with convex surfaces that generally face in an anterior direction D3 (FIG. 4). Each anterior-facing partial coil 158 is positioned between posterior-facing partial coils 160, or coils with convex surfaces that generally face in a posterior direction D4 (FIG. 4).

[0106] In some embodiments and as illustrated, the serpentine spring element 156, in an unloaded configuration, generally follows an arcuate path between the upper base 152 and the lower base 154, and an intermediate portion 162 of the serpentine spring element 156 is disposed anterior relative to an upper portion 164 adjacent the upper base 152 and a lower portion 166 adjacent the lower base 154. In other embodiments, the serpentine spring element 156 has different arrangements.

[0107] With continued reference to FIGS. 3 and 4 and additional reference to FIG. 5, the tension member 146 is positioned on an anterior side 168 of the serpentine spring element 156. The anterior side 168 of the serpentine spring element 156 includes a plurality of partial chocks 170, 172 (two of which are identified) that receive therebetween and position the tension member 146 along the serpentine spring element 156. The partial chocks 170, 172 are described in further detail below. With specific reference to FIGS. 4 and 5, the spring hinge member 144 further includes an upper bollard 174 adjacent the upper base 152 and a lower bollard 176 (FIG. 4) adjacent the lower base 154. The upper bollard 174 and the lower bollard 176 facilitate coupling the tension member 146 to the spring hinge member 144. More specifically, the upper bollard 174 receives an upper loop 178 of an upper end portion 180 of the tension member 146 and the lower bollard 176 receives a lower loop 182 of a lower end portion 184 (FIG. 4) of the tension member 146.

[0108] FIGS. 6-8 illustrate the first spring hinge member 144 separate from the tension member 146 and the support member 102 (both shown elsewhere). The serpentine spring element 156 has a width direction extending between a lateral side 185 and a medial side 187. In some embodiments and as illustrated, the serpentine spring element 156 has a uniform width W (FIGS. 6 and 8) proceeding from the upper base 152 and the lower base 154. In other embodiments and as shown elsewhere, the serpentine spring element 156 has a varying or non-uniform width W proceeding from the upper base 152 and the-16- DMSJJS.375277331.1FDBR Ref.: 473893.001217lower base 154. The serpentine spring element 156 also has a thickness direction that is perpendicular to the width direction. Referring specifically to FIG. 7, the anterior-facing partial coils 158 have a first thickness TA, the posterior-facing partial coils 160 have a second thickness Tp, and the second thickness Tp is greater than the first thickness TA.

[0109] FIGS. 6-8 also further illustrate the partial chocks 170, 172 and bollards 174, 176 coupled to the serpentine spring element 156. The partial chocks 170, 172 and bollards 174, 176 have shapes that facilitate coupling the tension member 146 to the serpentine spring element 156. For example and referring specifically to FIG. 8, each first partial chock 170 has a first concave surface 186 that contacts the tension member 146 and faces in a first direction (for example, a lateral direction D5), and each second partial chock 172 has a second concave surface 188 that contacts the tension member 146 and faces in a second, opposite direction (for example, a medial direction D6). Similarly and referring specifically to FIGS. 6 and 7, the upper bollard 174 and the lower bollard 176 each include a concave surface 190 that contacts the tension member 146 and faces in a third direction generally perpendicular to the first and second directions (for example, generally in the posterior direction D4).

[0110] FIG. 9 further illustrates one of the first partial chocks 170 of the spring hinge member 144. In some embodiments, the partial chocks may be provided with different shapes and arrangements. For example, FIG. 10 illustrates another partial chock 192, which may be used in place of one or more of the first partial chocks 170 and / or second partial chocks 172. The partial chock 192 has a similar to shape to the first partial chock 170, except that the partial chock 170 has a relatively small awning portion 194 adjacent to its concave surface 186, and the partial chock 192 has a relatively large awning portion 196 adjacent to its concave surface 198. In certain embodiments, the relatively small awning portion 194 facilitates rapidly detaching the tension member 146 (shown elsewhere) from the spring hinge member 144, and the relatively large awning portion 196 facilitates further securing the tension member 146 to the spring hinge member 144.

[0111] FIG. 11 illustrates the lateral tension member 146 separate from the other components of the hinge assembly 104. The tension member 146 is also referred to herein as a first tension member 146. As described above, the first-17- DMSJJS.375277331.1FDBR Ref.: 473893.001217tension member 146 is detachable from the system 100 and replaceable with other tension members having different deformation resistance characteristics (provided by different dimensions (for example, unloaded length, cross section, or the like) or material properties (for example, elastic modulus)) to provide the system 100 with different load carrying characteristics. FIG. 12 illustrates a second tension member 200 that is selectively attachable to and detachable from the hinge assembly 104. The second tension member 200 has a second resistance characteristic different than a first resistance characteristic of the first tension member 146, but is otherwise similar or substantially the same as the first tension member 146. In particular, the second tension member 200 has a shorter unloaded length than the first tension member 146.

[0112] FIGS. 13-15 illustrate a spring hinge member 300, according to another embodiment of the present disclosure. The spring hinge member 300 may replace the spring hinge member 144 of the first hinge assembly 104 and / or the second hinge assembly 106 in the brace system 100.

The grooves 304 receive and position the tension member 146 along the serpentine spring element 308.

[0113] FIGS. 16 and 17 illustrate a spring hinge member 400, according to another embodiment of the present disclosure. The spring hinge member 400 may replace the spring hinge member 144 of the first hinge assembly 104 and / or the second hinge assembly 106 in the brace system 100. The spring hinge member 400 is substantially the same as the spring hinge member 144, except that the serpentine spring element 402 has a varying or non-uniform width, between the lateral side 404 and the medial side 406, proceeding from the upper base 408 and the lower base 410. For example and as illustrated, the serpentine spring element 402 may be relative narrow near the upper portion 412, relatively wide near the intermediate portion 414, and relatively narrow near the lower portion 416. Stated another way, the serpentine spring element 402 includes an upper partial coil 418 that includes an upper width and is coupled to the upper-18- DMSJJS.375277331.1FDBR Ref.: 473893.001217base 408, a lower partial coil 420 that includes a lower width and is coupled to the lower base 410, and an intermediate partial coil 422 that includes an intermediate width and is disposed between the upper partial coil 418 and the lower partial coil 420. The intermediate width is greater than the upper width and / or the lower width. Additionally, the intermediate partial coil 422 may be referred to as a central intermediate partial coil 422 and the intermediate width may be referred to as a central intermediate width. The serpentine spring element 402 may also include an upper intermediate partial coil 424 having an upper intermediate width and positioned between the upper partial coil 418 and the central intermediate partial coil 422, and a lower intermediate partial coil 426 having a lower intermediate width and positioned between the lower partial coil 420 and the central intermediate partial coil 422. The upper intermediate width may be greater than the upper width and less than the central intermediate width, and lower intermediate width may be greater than the lower width and less than the central intermediate width.

[0114] In certain embodiments and as illustrated, the intermediate partial coil 422 has the maximum width WMAX of the serpentine spring element 402.Relatedly, the upper partial coil 418 and / or the lower partial coil 420 may have the minimum width WMIN of the serpentine spring element 402; that is, the upper partial coil 418 and the lower partial coil 420 may have a common minimum width WMIN.

[0115] Referring specifically to FIG. 17, due to the width variation of the serpentine spring element 402, the medial side 406 of the serpentine spring element 402 follows a curved path when viewed from the anterior side 428 of the spring hinge member 400, and the lateral side 404 of the serpentine spring element 402 follows a curved path when viewed from the anterior side 428 of the spring hinge member 400. The width may vary gradually proceeding toward the intermediate portion 414, as shown in FIG. 17, or alternatively, as shown in FIG.18, the width may vary more abruptly toward the intermediate portion 414.

[0116] FIGS. 19-24 illustrate a spring hinge member 500, according to another embodiment of the present disclosure. The spring hinge member 500 may replace the spring hinge member 144 of the first hinge assembly 104 and / or the second hinge assembly 106 in the brace system 100. The spring hinge member 500 is-19- DMSJJS.375277331.1FDBR Ref.: 473893.001217substantially the same as the spring hinge member 144, except that the serpentine spring element 501 is divided into an upper spring portion 604 and a lower spring portion 504 that are coupled at an intermediate joint 506. A fastener (not shown) received in an aperture 508 of the joint 506 may normally secure the upper spring portion 604 and the lower spring portion 504. The joint 506 permits the wearer to selectively configure the spring hinge member 500, for example, by temporarily loosening or detaching the fastener, in a straight configuration (FIGS.21 and 22), or a configuration in which both the upper spring portion 604 and the lower spring portion 504 are disposed in a common plane P1 (FIGS. 21 and 23 -for example, a plane generally parallel to the sagittal plane of the wearer), or an angled configuration (FIGS. 23 and 24), or a configuration in which the upper spring portion 604 and the lower spring portion 504 are not disposed in the common plane P1. To facilitate such reconfiguration, one of the spring portions (for example, the lower spring portion 504) includes an upright disk 510, the other of the spring portions (for example, the upper spring portion 604) includes an angled disk 512, and a spacer 514 with a corresponding upright surface 516 and angled surface 518 is positioned between the disks 510, 512. The spacer 514 may be pivoted relative to the upright disk 510 and the angled disk 512 to reconfigure the spring hinge member 500 from the straight configuration to the angled configuration. Additionally and with specific reference to FIGS. 20, 22, and 24, the disks 510, 512 may include protrusions 520 and the spacer 514 may include recesses 522 for receiving the protrusions 520, or vice versa, to facilitate coupling the upper spring portion 604 and the lower spring portion 504 at specific orientations of the spacer 514, thereby permitting the upper spring portion 604 and the lower spring portion 504 to be offset from each other at various discrete angled configurations.
