Soft tissue repair devices, systems, and methods
Devices, systems and/or methods for repairing soft tissue, such as, a lacerated tendon. A repair device includes a frame having a tubular structure with a longitudinal length and struts at least partially defining the tubular structure. The frame includes a first portion and a second portion with an intermediate portion therebetween, each extending along the longitudinal length. The intermediate portion is configured to substantially maintain a fixed position and is configured to be positioned over first and second ends of the lacerated tendon to substantially maintain the first end abutted against the second end. The first portion and the second portion of the frame are configured to be positioned over separate portions of the tendon and configured to move and elongate along a length of the respective first portion and second portion of the frame as the portions of the tendon elongate.
1. A method of repairing a tendon having a first tendon portion and a second tendon portion, the method comprising:

positioning the second tendon portion along the second portion of the repair device so that a second tendon end is positioned along the intermediate portion of the repair device and adjacent the first tendon end; and
anchoring the first portion and the second portion of the repair device to the first tendon portion and the second tendon portion, respectively;
wherein, upon anchoring the repair device to the first and second tendon portions, substantially maintaining the first tendon end abutted against the second tendon end positioned adjacent the intermediate portion of the repair device with the intermediate portion of the repair device substantially maintaining a fixed position along a length of the intermediate portion of the repair device; and
wherein, upon anchoring the repair device to the first and second tendon portions, facilitating movement of the first and second tendon portions anchored along a length of the respective first and second portions of the repair device such that the first and second portions of the repair device are movable as a load is placed on the tendon.
2. The method according to claim 1 , wherein the anchoring step comprises anchoring the first portion and the second portion of the repair device to the tendon with staples.
3. The method according to claim 1 , wherein the anchoring step comprises anchoring the first portion and the second portion of the repair device to the tendon with tines extending from the respective first portion and the second portion of the repair device.
4. The method according to claim 1 , wherein the anchoring step comprises anchoring the first portion and the second portion of the repair device to the tendon with integrally formed anchors extending from the respective first portion and the second portion of the repair device.
5. The method according to claim 1 , wherein the providing step comprises providing the repair device having at least a partially tubular structure that defines a bore.
6. The method according to claim 1 , wherein the providing step comprises providing the intermediate portion of the repair device to include a flexible member such that the flexible member is configured to substantially prevent elongation along the length of the intermediate portion.
7. The method according to claim 1 , wherein the providing step comprises providing the first portion and the second portion of the repair device to each include an upper portion and a lower portion of the repair device such that the upper and lower portions are positioned on opposite sides of the tendon.
8. The method according to claim 7 , wherein the providing step comprises providing the upper and lower portions of the repair device to be coupled to each other.
9. The method according to claim 1 , wherein the positioning the first tendon portion step comprises inserting the first tendon portion into a bore of a tubular structure of the first portion of the repair device.
10. A method of repairing a tendon having a tendon portion at a repair site, the method comprising:
providing a repair device having a longitudinal length defining an axis, the repair device including a moveable portion and a stabilizing portion;
positioning the tendon portion along the moveable portion of the repair device so that a tendon end of the tendon portion is positioned along the stabilizing portion of the repair device; and
anchoring the moveable portion of the repair device to the tendon portion;
wherein, upon anchoring the repair device to the tendon portion, substantially maintaining the tendon end in a fixed position adjacent the stabilizing portion of the repair device with the stabilizing portion of the repair device substantially maintaining a fixed position along a length of the stabilizing portion of the repair device; and
wherein, upon anchoring the repair device to the tendon portion, facilitating movement of the tendon portion anchored along a length of the moveable portion of the repair device such that the moveable portion of the repair device is moveable as a load is placed on the tendon.
11. The method according to claim 10 , wherein the anchoring step comprises anchoring the moveable portion of the repair device to the tendon with staples.
12. The method according to claim 10 , wherein the anchoring step comprises anchoring the moveable portion of the repair device to the tendon with tines extending from the moveable portion of the repair device.
13. The method according to claim 10 , wherein the anchoring step comprises anchoring the moveable portion of the repair device to the tendon with integrally formed anchors extending from the moveable portion of the repair device.
14. The method according to claim 10 , wherein the providing step comprises providing the repair device having at least a partially tubular structure that defines a bore.
15. The method according to claim 10 , wherein the providing step comprises providing the stabilizing portion of the repair device to include a flexible member such that the flexible member is configured to substantially prevent elongation along the length of the stabilizing portion.
16. The method according to claim 10 , wherein the providing step comprises providing the moveable portion of the repair device to include an upper portion and a lower portion of the repair device such that the upper and lower portions are positioned on opposite sides of the tendon.
17. The method according to claim 16 , wherein the providing step comprises providing the upper and lower portions of the repair device to be coupled to each other.
18. The method according to claim 10 , wherein the positioning the tendon portion step comprises inserting the tendon portion into a bore of a tubular structure of the moveable portion of the repair device.
19. The method according to claim 10 , wherein, upon anchoring the movable portion to the tendon portion, moving the movable portion to an arcuate position as the moveable portion moves along a bend with the load placed on the tendon portion.
20. The method according to claim 1 , wherein, upon anchoring the first and second portions of the repair device, moving at least one of the first and second portions of the repair device to an arcuate position as the at least one of the first and second portions of the repair device move along a bend with the load placed on the tendon.
