Abstract

A method for securing a sleeve in a bore hole in bone. The method includes disposing at least a portion of a length of filament into the bore hole, and implanting the sleeve into the bore hole such that a first pathway extending through first and second ends of the sleeve opens in a direction toward the opening of the bore hole and in a direction toward the base of the bore hole. The method also includes pulling at least a portion of the length of filament through the first pathway of the sleeve, thereby forming a first loop configuration extending from the first end and at least one free end of the length of filament extending from the second end. Also included is passing the at least one free end through the first loop configuration to create a one-way cinch.

First claim

1 . A method for securing a sleeve in a bore hole in bone, the bore hole having an opening, a base and a wall extending between the base and opening, the method comprising the steps of:
disposing at least a portion of a length of filament into the bore hole; implanting the sleeve into the bore hole such that a first pathway extending through first and second ends of the sleeve opens in a direction toward the opening of the bore hole and in a direction toward the base of the bore hole; pulling at least a portion of the length of filament through the first pathway of the sleeve, thereby forming a first loop configuration extending from the first end and at least one free end of the length of filament extending from the second end; passing the at least one free end through the first loop configuration to create a one-way cinch.

2 . The method of claim 1 , wherein the length of filament is adapted to apply tension to a tissue in working relationship with the length of filament.

3 . The method of claim 1 , wherein the sleeve is made of filamentary material.

4 . The method of claim 1 , further comprising:
engaging the length of filament with an inserter device prior to the disposing step; and disengaging the inserter device from the length of filament after the pulling step.

5 . The method of claim 4 , wherein the inserter device includes a filament engagement element for engaging and retaining the length of filament, and wherein disengaging the inserter device from the first loop configuration includes moving the filament engagement element from a first position to a second position to release the single length of filament.

6 . The method of claim 1 , further comprising tensioning the at least one free end such that the first loop configuration, with the at least one free end positioned therethrough, travels toward and into the first pathway of the sleeve.

7 . The method of claim 1 , wherein the sleeve further includes a sidewall and a plurality of fenestrations extending through the sidewall into the first pathway, and wherein when the sleeve is implanted in the bore hole, each of the plurality of fenestrations are disposed adjacent to and open towards the wall of the bore hole.

8 . The method of claim 1 , prior to the pulling step, further comprising:
pulling the at least one free end and the at least a portion of the length of filament into and through a second pathway in the sleeve from the first end of the sleeve; and maneuvering the at least one free end and the at least a portion of the length of filament around a boundary separating the first and second pathways.

9 . The method of claim 8 , wherein the boundary is a tab formed from a portion of the sleeve.

10 . The method of claim 8 , wherein the first and second pathways intersect at at least one location along the length of the sleeve.

11 . A method for securing a sleeve in a bore hole in bone, the bore hole having a base, an opening, and a wall disposed between the base and opening, the method comprising the steps of:
implanting the sleeve into the bore hole, the sleeve having a length defined between a first end and a second end and a first pathway extending along the length of the sleeve; passing at least a portion of a length of filament through the first pathway from the second end through the first end such that the at least a portion of the length of filament forms a first loop configuration that extends from the first pathway at the first end and at least one free segment of the length of filament having a free end that extends from the second end; and passing the free end of the at least one free segment through the first loop configuration such that the first loop configuration, with the free end positioned therethrough, forms a one-way cinch.

12 . The method of claim 11 , wherein the first loop configuration and the first end of the sleeve traps the at least first free segment to form the one-way cinch.

13 . The method of claim 11 , prior to the passing steps, further comprising the step of engaging the at least a portion of the length of filament with an inserter device.

14 . The method of claim 13 , further comprising disengaging the inserter device from the length of filament after the step of passing the at least a portion of the length of filament through the first pathway to form the first loop configuration.

15 . The method of claim 14 , wherein disengaging the inserter device from the first loop configuration includes actuating a filament engagement element to release the length of filament.

16 . The method of claim 11 , wherein the sleeve further includes an outer surface and a plurality of openings extending from the outer surface into the first pathway, and wherein when the sleeve is implanted in the bore hole, each of the plurality of openings are disposed adjacent to and open towards the wall of the bore hole.

17 . The method of claim 11 , wherein the sleeve further includes a second pathway juxtaposed with the first pathway, and further comprising, prior to the step of passing the at least a portion of the length of filament through the first pathway, passing the free end and the at least a portion of the length of filament through the second pathway from the first end of the sleeve through the second end of the sleeve.

18 . The method of claim 17 , wherein the first and second pathways intersect at at least one location along the length of the sleeve.

19 . The method of claim 11 , wherein the sleeve is made of filamentary material.

20 . A method for securing a sleeve in a bore hole in bone, the bore hole having a base, an opening, and a wall disposed between the base and opening, the method comprising:
implanting the sleeve into the bore hole such that a first end of the sleeve is disposed adjacent the opening of the bore hole and a second end of the sleeve is disposed adjacent the base of the bore hole, such that in this position the sleeve stands in a vertical configuration within the bore hole; passing a portion of filament into and along a first pathway of the sleeve; maneuvering the portion of filament around a boundary between the first pathway and a second pathway of the sleeve; forming a first loop configuration extending from the first end of the sleeve; passing the portion of filament through the first loop configuration forming a second loop configuration; and tensioning the portion of filament such that the first loop configuration is pulled towards the first end of the sleeve.
