[0001] This application claims the benefit of United States Provisional Patent Application No. 63 / 746,200, filed on January 16, 2025, which is incorporated herein in its entirety.BACKGROUND

[0002] Completely replacing damaged tissue often requires using harvested tissue, such as tendons or ligaments, to implant into a patient. The harvested tissue can be tensioned during its preparation for implantation. The harvested tissue is typically prepared by whip stitching various aspects of the harvested tissue, such as the ends, to prepare it for use. When using conventional graft preparation boards, a harvested tissue is attached to clamps on the board and pulled tight. Medical personnel then stitch desired portions of the harvested tissue with a suture. When suturing the tissue on the board, the person must pass the suture under the tissue and switch hands with the suture after each stitch in preparation for the next stitch. Doing so typically causes the loss of tension in the suture resulting in undesirable slack being introduced to the suture.SUMMARY

[0003] A graft support system configured to support a piece of tissue, such as, but not limited to, a graft, in a manner to enable graft preparation is disclosed. In particular, the graft support system may be configured to enable sutures to be easily passed around a piece of tissue held securely above a surface while the suture remains under tension to better facilitate graft preparation with whip stitching and the like. The graft support system may include a suture receiver configured to receive a suture under tension in a suture receiving opening and release the suture under tension from a suture release opening after moving a suture receiver base from a first position in which the suture receiving opening is open to a second position in which the suture release opening is open. As such, the suture is moved from one side of the tissue securement assembly to the other side easily, quickly and without losing tension on the suture.

[0004] In at least one embodiment, the graft support system may be configured to support one or more tissue securement assemblies, such as, but not limited to one or more posts or tissue clamps arms forming a tissue clamp, above a surface, such as, but not limited to, a system base. The tissue receiver may be supported by a movable suture receiver, which is in turn 2ACTIVE 718108765vlGT Ref: 208356.013005Arthrex Ref: 2024-123-KHS-PRV supported by a suture receiver support. In at least one embodiment, the suture receiver support may be a shaft, which may be, but is not required to be, removable from a system base. The movable suture receiver enables a suture to be held under tension and moved from one side of the graft support system to another side.

[0005] The graft support system may also include a medical device support system configured to support a medical device via an adjustable receiver configured to releaseably secure a medical device. The adjustable receiver provides flexibility to a healthcare professional to attach any desired medical device to the adjustable receiver. As such, the medical device support system operates as a universal clamp. The adjustable receiver may be formed from first and second supports that are configured to removably grasp a medical device. In at least one embodiment, the second support may be movable relative to the first support. A releasable connection system may be configured to make one or both of the first and second supports movable relative to each other. The releasable connection system may include a threaded bolt with a handle facilitating tighten and loosening of the bolt by hand. As such, as user can hand tighten the releasable connection system so that the medical device support system can grasp and hold a medical device in place.

[0006] The medical device support system may include a medical device engagement surface. In particular, the medical device engagement surface may be a V-shaped groove or another shape configured to enhance the ability of the medical device support system to grasp a medical device.

[0007] The graft support system may be configured to have smoother lateral movement of the suture receiver body, and attached tissue receiver, relative to the suture receiver base. As such, movement of the tissue receiver relative to the support member is easier when moving a suture from one side of the tissue securement assembly and suture receiver to the other side easily, quickly and without losing tension on the suture. The suture receiver body may include a base support member, and first and second arms that are separated to form a suture receiving chamber. The first and second arms may have a curved longitudinal axis. The receiver in the suture receiver base may have a curved longitudinal axis matching the curved longitudinal axis of the first and second arms. The receiver in the suture receiver base may include one or more bearing surfaces.

[0008] The graft support system may include a quick detachment system configured to enable quick release of the tissue receiver, graft clamps and related components. The quick detachment system may enable release of the tissue receiver, graft clamps and related3ACTIVE 718108765vlGT Ref: 208356.013005Arthrex Ref: 2024-123-KHS-PRV components by simply rotating the tissue receiver approximately 45 degrees or more. The quick detachment system may be formed from a quick release opening in the suture receiver base forming the receiver. As such, the receiver in the suture receiver base may include a quick release opening facing away from the tissue configured to be retained by the tissue receiver, whereby the quick release opening is sized to allow removal of the first and second arms thru the quick release opening. The quick release opening may be configured to span at least half of a cross-section of the receiver in the suture receiver base. In at least one embodiment, the receiver in the suture receiver base may be cylindrical, and the quick release opening may form at least half of a cross-section of the receiver in the suture receiver base.

[0009] An advantage of the graft support system is that the system may include a medical device support system configured to support a medical device via an adjustable receiver configured to releaseably secure a medical device. The adjustable receiver provides flexibility to a healthcare professional to attach any desired medical device to the adjustable receiver. As such, the medical device support system operates as a universal clamp.

[0010] Another advantage of the graft support system is that graft support system may be configured to have smoother lateral movement via a curved longitudinal axis of the first and second arms positioned in a receiver with a curved longitudinal axis. As such, movement of the tissue receiver relative to the support member is easier when moving a suture from one side of the tissue securement assembly and suture receiver to the other side easily, quickly and without losing tension on the suture.

[0011] Yet another advantage of the graft support system is that graft support system may include a quick detachment system configured to enable quick release of the tissue receiver, graft clamps and related components for cleaning. The quick detachment system may enable release of the tissue receiver, graft clamps and related components by simply rotating the tissue receiver approximately 45 degrees or more.

[0059] As shown in Figures 1-46, a graft support system 10 may be configured to support a piece of tissue 12, such as, but not limited to, a graft, in a manner to enable graft preparation. In particular, the graft support system 10 may be configured to enable sutures 14 to be easily passed around a piece of tissue 12 held securely above a surface 16 while the suture 14 remains under tension to better facilitate graft preparation with whip stitching and the like. The graft support system may include a suture receiver 24 configured to receive a suture 14 under tension in a suture receiving opening 50 and release the suture 14 under tension from a suture release opening 54 after moving a suture receiver base 44 from a first position 82 to a second position 8ACTIVE 718108765vlGT Ref: 208356.013005Arthrex Ref: 2024-123-KHS-PRV 84. As such, the suture 14 is moved from one side 28 of the tissue securement assembly 35 and suture receiver 24 to the other side 30 easily, quickly and without losing tension on the suture 14.

[0060] In at least one embodiment, the suture receiver 24 may be configured to move a suture receiver base 44 between a first position 48, as shown in Figure 9, thru a middle position, as shown in Figure 10, to a second position 52, as shown in Figure 11. The suture receiver 24 may receive a suture 14 under tension on a first side 28 of the suture receiver 24 when the suture receiver base 44 is in the first position 48 and release the suture 14 under tension on a second side 30 of the suture receiver 24 once the suture receiver base 44 has been moved to the second position 52. All the while, in at least one embodiment, the suture 14 has remained under constant tension. A user has not felt it necessary to switch hands with the suture 14 or in some manner lose tension on the suture 14.

[0061] The graft support system 10 may include a tissue receiver support base 18, as shown in Figures 3-7, 12 and 17 configured to support one or more tissue receivers 19, which may be, but are not limited to being, a tissue clamp 20, and a suture receiver support 22 configured to support the tissue receiver support base 18 remote from the surface 16, which may be, but is not limited to being, a system base 34. The tissue receiver support base 18 may be coupled to the suture receiver 24. The suture receiver 24 may, in turn, be supported by a suture receiver support 22. In such a configuration, the suture receiver 24 may be supported remotely from the surface 16 by the suture receiver support 22, and the tissue receiver support base 18 may be supported remote relative to the surface 16 by the suture receiver support 22. Thus, the suture receiver support 22 may’ hold the suture receiver 24, the tissue receiver support base 18 and the tissue receiver 19 above a support base 18.

[0062] The suture receiver 24, as shown in Figure 3-7, 9-22, may be configured to enable a stitch to be formed in the tissue 12, and the suture 14 to be looped around the tissue 12 while maintaining the suture 14 under constant tension by receiving a portion of a suture under tension 26 extending from a tissue 12 held by the tissue receiver 19, w hereby the portion of the suture under tension 26 remains under tension by force applied to the suture 14 such that the portion of the suture under tension 26 is manipulated from a first side 28 of the tissue securement assembly 35 and suture receiver 24 to a second side 30 of the tissue securement assembly 35 and suture receiver 24. As such, a user may be better able to create whip stitching and the like during graft preparation by keeping the suture 14 under constant tension.

[0063] In at least one embodiment, the graft support system 10 may include a suture9ACTIVE 718108765vlGT Ref: 208356.013005Arthrex Ref: 2024-123-KHS-PRV receiver support 22 configured to support the tissue receiver support base 18 and the suture receiver 24 remote from the surface 16. The suture receiver support 22 may be formed from one or more support members 38 configured to be removably attached to the surface 16. In at least one embodiment, the support member 38 may be, but is not limited to being, a shaft. The shaft may have a cylindrical cross-sectional shape or other shaped cross-section. The support member 38 may be configured to be removably attached to the surface 16. In at least one embodiment, the support member 38 may include one or more releasable connection systems 32 positioned distally of the suture receiver 24. In at least one embodiment, the releasable connection system 32 may be positioned on a distal end 40 of the support member 38 and may include one or more slots 42 configured to mate with protrusions 43, as shown in Figure 8, in a base structure configured to receive the support member 38. The slots 42 assist in preventing rotation of the support member 38 within the base structure.

[0064] The graft support system 10 may include a system base 34 configured to receive the support member 38 and to enable the support member 38 to extend from and to support a piece of tissue 12 in the tissue securement assembly 35 above the system base 34. The system base 34 may also include a second tissue securement assembly 36. The system base 34 may have any configuration enabling the first and second tissue securement assemblies 35. 36 to extend away from the system base 34 orthogonally, or nonorthogonally and nonparallel to the system base 34. The first and second tissue securement assemblies 35, 36 may be fixedly or movably attached to the system base 34. In at least one embodiment, the system base 34 may be configured to rest on top of a benchtop, tabletop or the like. In other embodiments, the system base 34 may be fixedly attached to a support structure such as, but not limited to a bench or a table. The suture receiver 24 may be supported above the system base 34 via the suture receiver support 22, such as, but not limited to, the one or more support members 38.

[0065] In another embodiment, as shown in Figure 22, the suture receiver 24 may be configured to support one or more tissue receivers 19, which may be first tissue securement assembly 35, above a surface 16, such as, but not limited to, a system base 34. In other words, the suture receiver 24 may be sized and configured to rest on or otherwise be attached to the surface 16 or other structure or surface and enable a tissue securement assembly 35 to hold a piece of tissue 12 sufficiently far enough above the surface 16 to enable a user to manipulate a suture 14 from one side to the other and to stitch the tissue 12. In such as configuration, the suture receiver 24 may include a suture receiver support 22 integrally formed within the suture receiver 24. In at least one embodiment, the suture receiver 24 may be attached to a tissue10ACTIVE 718108765vlGT Ref: 208356.013005Arthrex Ref: 2024-123-KHS-PRV receiver support base 18 or otherwise secured in place, such as to a bench, tabletop or other surface or support.

[0066] In at least one embodiment, as shown in Figure 19, the graft support system 10 may include a rotatable support structure 150 configured to enable the first and second tissue securement assemblies 35, 36 to be rotated along an axis generally aligned with a longitudinal axis of the tissue material 12 extending between the first and second tissue securement assemblies 35, 36. The rotatable support structure 150 may enable a user to easily work on and observe the tissue material 12. The description of the graft support system 10 herein describes the first tissue securement assembly 35 as including a suture receiver 24 enabling a suture 14 attached to the tissue 12 to remain under tension while being passed from one side 28 to another side 30 without having to pass the suture from one hand to another and possibly lose tension. In at least one embodiment, both the first and second tissue securement assemblies 35, 36 include suture receivers 24 and one or more of the other components set forth herein, as shown in Figures 2, 18 and 19.

[0067] The suture receiver 24 may enable a suture 14 attached to the tissue 12 to remain under tension while being passed from one side 28 to another side 30 without having to pass the suture from one hand to another and possibly lose tension. In particular, the suture receiver 24 may be configured to enable a stitch to be formed in the tissue, and the suture 14 to be looped around the tissue while maintaining the suture 14 under constant tension by receiving a portion of a suture under tension 26 extending from the tissue 12 held within the tissue receiver 19. The portion of the suture under tension 26 remains under tension by force applied to the suture 14 by a user such that the portion of the suture 14 under tension is manipulated from a first side 28 of the tissue securement assembly 35 and suture receiver 24 to a second side 30 of the tissue securement assembly 35 and suture receiver 24.

[0068] In at least one embodiment, the suture receiver 24 may include a suture receiver base 44 configured to slidably receive a suture receiver body 46 whereby, in a first position 48, as shown in Figures 3, 9, 12, 13, 15 and 17, a suture receiving opening 50 is open to receive a suture 14 under tension from the first side 28 of the tissue securement assembly 35 and suture receiver 24 and, in a second position 52, as shown in Figures 4, 11, 14 and 16, a suture release opening 54 is open to release a suture 14 under tension from the second side 30 of the tissue securement assembly 35 and suture receiver 24. The suture receiver body 46 may include a base support member 56 and first and second arms 58, 60 separated to form a suture receiving chamber 62. In such configuration, the suture receiver 24 may be configured to move the suture11ACTIVE 718108765vlGT Ref: 208356.013005Arthrex Ref: 2024-123-KHS-PRV receiver base 44 between the first position 48, as shown in Figure 9, thru the middle position, as shown in Figure 10, to the second position 52, as shown in Figure 11.

[0069] In at least one embodiment, the suture receiver 24 may be formed from a suture receiver body 46 that is slidable relative to the suture receiver base 44. The suture receiver body 46 may include a base support member 56 and first and second arms 58, 60 separated to form a suture receiving chamber 62. The suture receiving chamber 62 may have any appropriate configuration enabling a suture to be received therein and moved from a first side 28 to a second side 30 of the tissue securement assembly 35 and suture receiver 24. In a first position 48, a suture receiving opening 50 is open on a first side 28 of the tissue securement assembly 35 and suture receiver 24. At the same time, the suture release opening 54 on the second side 30 is closed and the second arm 60, which is on the second side 30, is supporting the suture receiver 24. In the first position 48, the first side 28 of the suture receiver 24, in particular, the first arm 58, is unsupported. As such, a suture 14 is capable of being inserted into the suture receiving opening 50 on the first side 28 of the suture receiver 24 without obstruction. The suture receiving opening 50 receives a suture 14 under tension from the first side 28 of the suture receiver 24 via the suture receiving opening 50.

[0070] The suture receiver base 44 of the suture receiver 24 may be moved to a second position 52 in which the suture release opening 54 is open and the suture receiving opening 50 is closed. In this position, the suture receiver 24 is supported by the first side 28 of suture receiver 24 and releases a suture 14 under tension from the second side 30 of the suture receiver 24 via the suture release opening 54.

[0071] The suture receiver 24 may also include a retention mechanism 64 configured to releasably attach the suture receiver 24 to the suture receiver base 44. In at least one embodiment, the retention mechanism 64 may be, but is not limited to being a first retainer 66 on a distal end 68 of the first arm 58 and a second retainer 70 on a distal end 72 of the second arm 60. The first and second retainers 66. 70 may be aligned along a longitudinal axis 74 enabling the suture receiver body 46 to be attached to the suture receiver base 44 by sliding the first and second retainers 66, 70 into at least one receiver 76 in the suture receiver base 44. In at least one embodiment, the first and second retainers 66, 70 may be, but are not limited to being, cylindrical. The cross-sectional shape of the first and second retainers 66, 70 may be another appropriate configuration other than cylindrical still enabling the suture receiver body 46 to slide relative to the suture receiver base 44 when in use. The suture receiver base 44 may be configured to slidably retain the suture receiver body 46 such that the movement of the12ACTIVE 718108765vlGT Ref: 208356.013005Arthrex Ref: 2024-123-KHS-PRV suture receiver body 46 is limited to movement along a single axis 73, which in at least one embodiment, is aligned, and, in at least one embodiment, is coaxial, with the longitudinal axis 74.

[0072] The graft support system 10 may also include a suture receiver body restraint 78 configured to limit movement of the suture receiver support 46 between the first and second positions 48, 52 while maintaining support of the tissue receiver support base 18 by the suture receiver support 22. In particular, the suture receiver body restraint 78 ensures that the suture receiver body 46 and tissue securement assembly 35 attached thereto is supported either by the first arm 58 or the second arm 60 and prevents the suture receiver body 46 and tissue securement assembly 35 from falling off the suture receiver base 44. In at least one embodiment, the suture receiver body restraint 78 may include one or more members extending from the suture receiver base 44 into the suture receiving chamber 62. The suture receiver body restraint 78 may be, but is not limited to being, a pin 80 positioned in the suture receiving chamber 62 and attached to the suture receiver base 44. As the suture receiver body 46 moves laterally, the suture receiver body 46 contacts the suture receiver body restraint 78 and movement stops.

[0073] In at least one embodiment, the suture receiver body restraint 78 may be a pin 80, as shown in Figures 5, 6, 13, 15, 16 and 17 extending from a first portion 82 of the suture receiver base 44 to a second portion 84 of the suture receiver base 44 and positioned within the suture receiving chamber 62. In another embodiment, as shown in Figure 17, the suture receiver body restraint 78 may include one or more members 86 extending from the suture receiver body 46 to limit movement of the suture receiver body 46 between the first and second positions 48, 52 while maintaining support of the tissue receiver support base 18 by the suture receiver support 22. In at least one embodiment, the suture receiver body restraint 78 may include one or more members 86 extending from the suture receiver body 46 or one or more members 80 extending from the suture receiver base 44, or both, to limit movement of the suture receiver body 46 between the first and second positions 48, 52 while maintaining support of the tissue receiver support base 18 by the suture receiver support 22.

[0074] The graft support system 10 may also include one or more tissue receivers 19. In at least one embodiment, the tissue receiver 19 may be one or more posts 21, as shown in Figure 20. extending nonorthogonal and nonparallel to a longitudinal axis 23 of a graft 12 extending between first and second tissue receiver assemblies 35, 36. In at least one embodiment, one or more posts 21 may be positioned orthogonal to the longitudinal axis 23 of13ACTIVE 718108765vlGT Ref: 208356.013005Arthrex Ref: 2024-123-KHS-PRV a graft 12 extending between first and second tissue receiver assemblies 35, 36. As such, the post 21 may receive a piece of material 12, such as a graft, such that the post 21 secures the piece of material 12 once the post 21 is inserted into a hole 25, as shown in Figure 21, in the piece of material 12. such as, but not limited to being, a graft. The post 21 enables a graft 12 to be easily attached to and detached from the graft support system 10.

[0075] The tissue receiver 19 is not limited to being a post 21 but may also be any other structure configured to retain a piece of material 12. In at least one embodiment, the tissue receiver 19 may be one or more tissue clamps 35 coupled to the tissue receiver support base 18 and configured to grasp a graft 12, as shown in Figures 2-7, 12, 14 and 17-19. The tissue clamp 35 may be formed from first and second clamp arms 90, 92, whereby the second arm 92 is pivotably coupled to the first arm 90 at the tissue receiver support base 18. The second clamp arm 92 may include a graft punch 94 at a distal end 96 of the second clamp arm 92, and the first clamp arm 90 may include a punch receiver 96. In at least one embodiment, the graft punch 94 may extend orthogonally from the second clamp arm 92, and in other embodiments, may extend nonorthogonally and nonparallel, from the second clamp arm 92.

[0076] In at least one embodiment, the punch receiver 98 may be an orifice 100 in the first clamp arm 90 near the distal end 95 of the first clamp arm 90 and aligned with the graft punch 94 on the second clamp arm 92 such that at least a portion of the graft punch 94 extends into the orifice 100 in the first clamp arm 90 when in a closed position. In a closed positioned of at least one embodiment, the distal end 102 of the graft punch 94 may extend into and through the orifice 100 in the first clamp arm 90. The orifice 100 may have any appropriate size. In at least one embodiment, the orifice 100 may be sized to be slightly smaller than an outer diameter 104 of a base 106 of the graft punch 94. As such, the orifice 100 stops movement of the graft punch 94 when the base 106 of the graft punch 94 contacts the first clamp arm 90 forming the orifice 100. The orifice 100 may stop movement of the second clamp arm 92 from rotating towards the first clamp arm 90 when the second clamp arm 92 is generally parallel with the first clamp arm 90.

[0077] In other embodiments, the first and second clamp arms 90, 92 may be configured with distal ends having any configuration enabling the first and second clamp arms 90, 92 to grasp tissue. The first and second clamp arms 90. 92 may be configured identically, as shown in Figures 18 and 19, or differently, as shown in Figure 2. The first and second clamp arms 90, 92 may include grip enhancements, such as, but not limited to, teeth, multiple points, jagged14ACTIVE 718108765vlGT Ref: 208356.013005Arthrex Ref: 2024-123-KHS-PRV edges, knurled surfaces, etched surfaces, abrasives and adhesives. In at least one embodiment, one or more of the first and second clamp arms 90, 92 may include convention clamp ends.

[0078] The second clamp arm 92 may be biased to rotate away from the first spring arm 90. In at least one embodiment, a spring 108, such as, but not limited to, a torsion spring, as shown in Figure 5, may be used to bias the second clamp arm 92 away from the first spring arm 90. The torsion spring may be positioned proximate to a pin 110 forming a pivot point 112 for the second clamp arm 92 relative to the first spring arm 90.

[0079] The graft support system 10 may also include a tissue receiver support base 18 configured to support one or more tissue clamps 35. The tissue receiver support base 18 may have any appropriate configuration capable of supporting a tissue clamp 35. In at least one embodiment, the tissue receiver support base 18 may be a generally planar member configured to enable a clamp 35 to be attached thereto. The first clamp arm 90 may extend from a distal end of the tissue receiver support base 18. The second clamp arm 90 may also be rotatably coupled to the tissue receiver support base 18. In at least one embodiment, as shown in Figures 3-8, 12, 14 and 17, the second clamp arm 90 may be rotatably coupled to the tissue receiver support base 18 between distal and proximal ends of the tissue receiver support base 18.

[0080] The graft support system 10 may also include a clamp arm retainer 114 configured to releasably secure the second clamp arm 92 in a fixed position relative to the first clamp arm 90. The clamp arm retainer 114 may include a retainer arm 16 pivotably coupled to the second clamp arm 92 at a pivot point 120. The retainer arm 16 may include an actuator end 118 configured to be actuated by a user by pivoting the actuator end 118 of the retainer arm 116 relative to the pivot point 120 where the retainer arm 116 is pivotably coupled to the second clamp arm 92.

[0081] In another embodiment, as shown in Figures 30-43, the graft support system 10 may be configured to have smoother lateral movement of the suture receiver body 46, and attached tissue receiver 19, relative to the suture receiver base 44. As such, movement of the tissue receiver relative to the support member 38 is easier when moving a suture 14 from one side 28 of the tissue securement assembly 35 and suture receiver 24 to the other side 30 easily, quickly and without losing tension on the suture 14. In particular, the graft support system 10 may include one or more tissue receivers 19 configured to retain a tissue 12. The graft support system 10 may include a suture receiver 24 supported remotely from at least one surface 16 and configured to support the tissue receiver 19 remote relative to the surface 16 such that material can be passed between the surface 16 and the tissue 12 supported by the graft support15ACTIVE 718108765vlGT Ref: 208356.013005Arthrex Ref: 2024-123-KHS-PRV system 10. The suture receiver 24 may be configured to enable a stitch to be formed in the tissue 12 and the suture 14 to be looped around the tissue 12 while maintaining the suture 14 under constant tension by receiving a portion of a suture 14 under tension extending from the tissue 12 held within the tissue receiver 19, whereby the portion of the suture 14 under tension remains under tension by force applied to the suture 14 when the portion of the suture 14 under tension is manipulated from a first side 28 of the suture receiver 24 to a second side 30 of the suture receiver 24. The suture receiver 24 may include a suture receiver base 44 slidably receiving a suture receiver body 46 in a receiver 76 whereby, in a first position 48, a suture receiving opening 54 is open to receive a suture 14 under tension from the first side 28 of the suture receiver 24 and, in a second position 52, a suture release opening 54 is open to release a suture 14 under tension from a second side 30 of the suture receiver 24. The suture receiver body 46 may include a base support member 56, and first and second arms 58, 60 that are separated to form a suture receiving chamber 62. The first and second arms 58, 60 may have a curved longitudinal axis 160, as shown in Figures 37, 38 and 40-42. In at least one embodiment, the curved longitudinal axis 160 may have a radius of curvature 162 greater than 175 millimeters. In another embodiment, the curved longitudinal axis 160 may have a radius of curvature 162 between 150 millimeters and 250 millimeters.

[0082] The receiver 76 in the suture receiver base 44 may have a curved longitudinal axis 164 matching the curved longitudinal axis 160 of the first and second arms 58, 60. In at least one embodiment, the curved longitudinal axis 164 of the receiver 76 may have a radius of curvature 162 greater than 175 millimeters. In another embodiment, the curved longitudinal axis 164 of the receiver 76 may have a radius of curvature 162 between 150 millimeters and 250 millimeters.

[0083] The receiver 76 in the suture receiver base 44 may include one or more bearing surfaces 166. The bearing surface 166 may be formed from materials, such as, but not limited to metal, ceramic and polyethylene. The bearing surface 166 may also be a bearing formed from a needle bearing, a roller bearing, ball bearing or magnet bearing.

[0084] The graft support system 10 may also be configured to further reduce resistance to lateral movement of the suture receiver body 46, and attached tissue receiver 19, relative to the suture receiver base 44. In at least one embodiment, a length to diameter ratio of the first arm 58 may be at least 1.75 to 1. In another embodiment, the length to diameter ratio of the first arm 58 is at least 2 to 1. Similarly, a length to diameter ratio of the second arm 60 may be at least 1.75 to 1. In another embodiment, the length to diameter ratio of the second arm 60 may16ACTIVE 718108765vlGT Ref: 208356.013005Arthrex Ref: 2024-123-KHS-PRV be at least 2 to 1. This length to diameter ratio creates a relatively long length of the sliding mechanism formed by the first and second arms 58, 60 which reduces binding and allows for better constraint and alignment of the first and second arms 58, 60 within the track formed by the receiver 76 in the suture receiver base 44.

[0085] The graft support system 10 may include a quick detachment system 170, as shown in Figures 31-33, configured to enable quick release of the tissue receiver 19, graft clamps 20 and related components. The quick detachment system 170 may enable release of the tissue receiver 19, graft clamps 20 and related components by simply rotating the tissue receiver 19 approximately 45 degrees or more. The quick detachment system 170 may be formed from a quick release opening 172 in the suture receiver base 44 forming the receiver 76. As such, the receiver 76 in the suture receiver base 44 may include a quick release opening 172 facing away from the tissue 12 configured to be retained by the tissue receiver 19, whereby the quick release opening 172 is sized to allow removal of the first and second arms 58. 60 thru the quick release opening 172. The quick release opening 172 may be configured to span at least half of a crosssection of the receiver 76 in the suture receiver base 44. In at least one embodiment, the receiver 76 in the suture receiver base 44 may be cylindrical, and the quick release opening 172 may form at least half of a cross-section of the receiver 76 in the suture receiver base 44.

[0086] In use, the quick detachment system 170 may enable the components of the system 10 to be quickly disassembled for cleaning. In particular, the quick detachment system 170 may be configured to enable removal of the tissue receiver 19 from the suture receiver base 44 upon rotating the tissue receiver 19 from a tissue support position 174 to a tissue receiver removal position 176. The suture receiving chamber 62 may be configured to receive a suture 14 and to prevent removal of the tissue receiver 19 in a tissue support position 174 while also enabling removal of the tissue receiver 19 from the suture receiver base 44 upon rotating the tissue receiver 19 from the tissue support position 174 to the tissue receiver removal position 176. In the tissue support position 174, the first and second arms 58. 60 of the suture receiver body 46 engage the receiver 76 and are prevented from moving towards the tissue 12. As the tissue receiver 19 is rotated away from system base 34 and an edge of the suture receiver body 46 forming the suture receiving chamber 62 clears a top surface 178 of the suture receiver body 46, the first and second arms 58, 60 of the suture receiver body 46 and connected components, such as the tissue receiver 19, may be moved laterally in the direction of release force 180 to displace the first and second arms 58, 60 from the receiver 76. Doing so separates the suture receiver body 46 and attached tissue receiver 19 from the suture receiver and suture receiver17ACTIVE 718108765vlGT Ref: 208356.013005Arthrex Ref: 2024-123-KHS-PRV support 22, thereby enabling the suture receiver body 46 and attached tissue receiver 19 to be cleaned.

[0087] In another embodiment, a medical device support system 190 is disclosed, as shown in Figures 44-46. The medical device support system 190 may be configured to support a medical device 192 via an adjustable receiver 194 configured to releaseably secure a medical device. The adjustable receiver 194 provides flexibility to a healthcare professional to attach any desired medical device to the adjustable receiver 194. The adjustable receiver 194 may be formed from first and second supports 196, 198 that are configured to removably grasp a medical device. In at least one embodiment, the second support 198 may be movable relative to the first support 196. A releasable connection system 200 may be configured to make one or both of the first and second supports 196, 198 movable relative to each other. The releasable connection system 200 may include a threaded bolt with a handle facilitating tighten and loosening of the bolt by hand. As such, as user can hand tighten the releasable connection system 200 so that the medical device support system 190 can grasp and hold a medical device in place.

[0088] The medical device support system 190 may include a medical device engagement surface 202. In particular, the medical device engagement surface 202 may be a V-shaped groove configured to enhance the ability of the medical device support system 190 to grasp a medical device. The medical device engagement surface 202 may also be an L-shaped surface to enhance the ability of the medical device support system 190 to grasp a medical device. In other embodiments, the medical device support system 190 may have other configurations that enhance the ability of the medical device support system 190 to grasp a medical device. The medical device may be, but is not limited to being needle holder, graspers, suture retrievers, suture passer and clamps.

[0089] The medical device support system 190 may include one or more of the elements previously described herein. The description of those elements are not repeated here but are incorporated here and applied to the medical device support system 190.

[0090] During use, the graft support system 10 may be used to grasp and hold a piece of tissue 12 under tension above a surface 16, which in at least one embodiment as shown in Figures 2, 7, 18, 19 and 22, entails the first and second tissue securement assemblies securely grasping a piece of tissue 12 to support the tissue 12 above the support base 34 such that suture attached to the tissue 12 to remains under tension while being passed from one side 28 to another side 30 without having to pass the suture 14 from one hand to another and possibly18ACTIVE 718108765vlGT Ref: 208356.013005Arthrex Ref: 2024-123-KHS-PRV lose tension. A piece of tissue 12 may be held securely by the second tissue securement assembly 36. The piece of tissue 12 may be pulled tight and moved between the distal ends 95, 96 of the first and second clamp arms 90, 92 so that the graft punch 94 may grasp the piece of tissue 12 and retain the tissue 12 extending between the first and second tissue securement assemblies 35, 36. With the first and second clamp arms 90, 92 in an open position in which the graft punch 94 is separated from the orifice 100, such as when the first and second clamp arms 90, 92 are separated to a maximum open position as limited by stop 138, the piece of tissue 12 may be properly positioned for engagement and the second clamp arm 92 may be pushed towards the first clamp arm 90 via the thumb pad 136 or by pushing the second clamp arm 96 towards the first clamp arm 90.

[0091] Once the piece of tissue 12 is secured and extending between the first and second tissue securement assemblies 35, 36, a needle may be passed through the tissue 12 and the suture 14 pulled tight to place the suture 14 under tension, as shown in Figure 24. The tag end 140 of the suture 14 may be pulled tight to place the suture under tension. The portion of the suture under tension 26 may be pulled into the suture receiving chamber 62, as shown in Figure 25, via the suture receiving opening 50 of the suture receiver 24 on the first side 28 of the tissue securement assembly 36 and suture receiver 24. In such process, the portion of the suture under tension 26 may remain under constant tension. The suture receiver body 46 may then be moved from the first position 48 to the second position 52 whereby the suture release opening 54 is opened and the suture receiving opening 50 is closed. The suture under tension 26 may be moved within the suture receiving chamber 62, as shown in Figure 25 and pulled out of the suture release opening 54, as shown in Figures 26 and 27. Doing so enables the suture 14 under tension to be moved from the first side 28 of the tissue securement assembly 35 and suture receiver 24 to the second side 30. In other words, a user may pull the suture 12 tight and move the suture from the first side 28 of the tissue securement assembly 35 and suture receiver 24 to the second side 30 of the tissue securement assembly 35 and suture receiver 24 while keeping the suture under tension. The tensioned tag end 140 of the suture 14 is then ready for the next stitch, as shown in Figure 28. The fully prepare piece of tissue 12 is shown in Figure 29.

[0092] A method of preparing a graft for implantation or other use may include graft support system 10 being used to grasp and hold a piece of tissue 12 under tension above a surface 16, which in at least one embodiment as shown in Figure 23, and may entail the first and second tissue securement assemblies securely grasping a piece of tissue 12 to support the tissue 12 above the support base 34 such that suture attached to the tissue 12 remains under19ACTIVE 718108765vlGT Ref: 208356.013005Arthrex Ref: 2024-123-KHS-PRV tension while being passed from one side 28 to another side 30 without having to pass the suture 14 from one hand to another and possibly lose tension. The method may include a piece of tissue 12 being held securely by the second tissue securement assembly 36. The piece of tissue 12 may be pulled tight and moved between the distal ends 95, 96 of the first and second clamp arms 90, 92 so that the graft punch 94 may grasp the piece of tissue 12 and retain the tissue 12 extending between the first and second tissue securement assemblies 35, 36. With the first and second clamp arms 90, 92 in an open position in which the graft punch 94 is separated from the orifice 100, such as when the first and second clamp arms 90, 92 are separated to a maximum open position as limited by stop 138, the piece of tissue 12 may be properly positioned for engagement and the second clamp arm 92 may be pushed towards the first clamp arm 90 via the thumb pad 136 or by pushing the second clamp arm 96 towards the first clamp arm 90.

[0093] The method of preparing a graft may include, once the piece of tissue 12 is secured and extending between the first and second tissue securement assemblies 35, 36, passing a needle through the tissue 12 and pulling the suture 14 tight to place the suture 14 under tension, as shown in Figure 24. The method may include pulling the tag end 140 of the suture tight to place the suture under tension. The portion of the suture under tension 26 may be pulled into the suture receiving chamber 62, as shown in Figure 25, via the suture receiving opening 50 of the suture receiver 24 on the first side 28 of the tissue securement assembly 35 and suture receiver 24. In such method, the portion of the suture under tension 26 may remain under constant tension. The method may include moving the suture receiver body 46 from the first position 48 to the second position 52 whereby the suture release opening 54 is opened and the suture receiving opening 50 is closed. The method may include moving the suture under tension 26 within the suture receiving chamber 62, as shown in Figure 25, and out of the suture release opening 54, as shown in Figures 26 and 27. Doing so enables the suture 14 under tension to be moved from the first side 28 of the tissue securement assembly 35 and suture receiver 24 to the second side 30 of the tissue securement assembly 35 and suture receiver 24. In other words, a user may pull the suture 12 tight and move the suture from the first side 28 of the tissue securement assembly 35 and suture receiver 24 to the second side 30 while keeping the suture under tension. The tensioned tag end 140 of the suture 14 is then ready for the next stitch, as shown in Figure 28. The method may be replicated numerous times until a piece of tissue has been fully prepared, as shown in Figure 29.

[0094] Typical graft tissue preparation required a user to pass the suture from one side to20ACTIVE 718108765vlGT Ref: 208356.013005Arthrex Ref: 2024-123-KHS-PRV the other side of the graft underneath the graft while trying to maintain tension on the graft. Such was difficult and wasted time. In addition, it was not always possible to maintain tension on the suture. The graft support system 10 and the method of using the graft support system 10 enables a user, such as, but not limited to. a medical professional, to keep tension on a suture in preparation for another stitch when moving a tensioned tag end of the suture from one side of a clamp to a second side of the clamp without having to pass the suture from one hand to another. Rather, the tensioned tag end of the suture can remain in the same hand of the user. Such system and method saves time and greatly increases the likelihood that tension on the suture continue uninterrupted while the user is stitching the graft in preparation for implantation.
