Abstract

Disclosed herein are an implant with a suture passage and a method of attaching sutures to the same. The implant may include a suture pocket having a first pocket, a second pocket, and a suture hole disposed therebetween. The first pocket may have a first wall segment, the second pocket may have a second wall segment, and the suture hole may have a first sidewall segment extending from a first opening to a second opening. The first wall segment, the second wall segment, and the first sidewall segment may form a contiguous wall. A method of attaching a suture to the implant may include placing a tip of a suture needle on the first wall segment, sliding the suture needle into the first opening and pushing the suture needle through the suture hole.

First claim

The invention claimed is:

1. An implant having suture pockets comprising:
a first pocket having a first planar wall segment;
a second pocket having a second planar wall segment; and
a suture hole disposed between the first and second pockets, the suture hole having a first sidewall segment extending from a first opening to a second opening, the first planar wall segment adjoining the first opening and extending away from the first opening, the second planar wall segment adjoining the second opening and extending away from the second opening,
wherein the first planar wall segment, the second planar wall segment and the first sidewall segment of the suture hole form a planar wall such that a suture needle can be slidably guided along the first and second planar wall segments and the first sidewall segment of the suture hole; and wherein a plurality of suture holes are disposed between the first and second pockets.

2. The implant of claim 1 , wherein when a suture needle tip is placed on the first planar wall segment, the suture needle tip can be slidably guided across first planar wall segment and into the suture hole.

3. The implant of claim 1 , wherein the suture hole includes a second sidewall segment opposite the first sidewall segment, the second sidewall segment extending from the first opening to the second opening and defining a first length.

4. The implant of claim 3 , wherein the second sidewall segment is chamfered at the first opening.

5. The implant of claim 3 , wherein the second sidewall segment is chamfered at the second opening.

6. The implant of claim 3 , wherein a length of the suture hole measured from the first opening to the second opening is greater than a distance between the first sidewall segment and the second sidewall segment.

7. The implant of claim 1 , wherein the first sidewall segment is tangential to the suture needle when the suture needle is disposed within the suture hole.

8. The implant of claim 1 , wherein an upper wall and a lower wall connecting the first sidewall segment and the second sidewall segments are curved such that the suture hole is oblong shaped in a plane transverse to the first and second sidewalls.

9. The implant of claim 1 , wherein the plurality of suture holes are arranged vertically below each other.

10. The implant of claim 9 , wherein a vertical axis connecting the suture hole centers is offset to a vertical axis of the implant.

11. The implant of claim 1 , wherein the implant is any of a shoulder or hip prostheses.

12. The implant of claim 11 , wherein the first and second pockets are aligned along a bicipital groove.

13. An implant having a suture pocket comprising:
a first pocket having a first wall segment; and
a suture hole adjoining the first pocket, the suture hole having a first sidewall segment extending from a first opening to a second opening, the first wall segment adjoining the first opening and extending away from the first opening;
a second pocket having a second wall segment, the second wall segment adjoining the second opening and extending away from the second opening,
wherein the first wall segment and the first sidewall segment of the suture hole form a contiguous surface such that a suture needle can be slidably guided along the first wall segment and the first sidewall segment of the suture hole; and wherein a plurality of suture holes are disposed between the first and second pockets.

14. The implant of claim 13 , wherein the suture hole includes a second sidewall segment opposite the first sidewall segment, the second sidewall segment extending from the first opening to the second opening and defining a first length.

15. A method of suturing an implant, comprising:
providing an implant having suture pockets with a first pocket having a first wall segment, a second pocket having a second wall segment, and a suture hole disposed between the first and second pockets, the suture hole having a first sidewall segment extending from a first opening to a second opening, the first wall segment adjoining the first opening and extending away from the first opening, the second wall segment adjoining the second opening and extending away from the second opening, wherein the first wall segment, the second wall segment and the first sidewall segment of the suture hole form a contiguous surface; wherein a plurality of suture holes are disposed between the first and second pockets
placing a tip of a suture needle on the first wall segment;
sliding the suture needle into the first opening; and
pushing the suture needle through the suture hole such that the tip of the suture needle exits the second opening.

16. The method of claim 15 , wherein during the placing, sliding and pushing steps, the suture needle contacts only the contiguous surface.
