Abstract

An anchor delivery tool is described. The tool includes a shaft and a handle coupled to a proximal portion of the shaft. The handle includes a hub, with a knob and a nose cone coupled to the hub. The knob and nose cone may be spring loaded so as to selectively retain a length of suture disposed therebetween. The tool further includes an anchor, such as a suture anchor, coupled to a distal portion of the shaft.

Claims (21)

1. An anchor delivery tool comprising:

a shaft and a handle coupled to the shaft, the handle including a hub, a nose cone and a knob coupled to the hub, wherein the knob is configured to slide relative to the nose cone so as to selectively retain and release a length of suture disposed along an outer surface of the knob, and wherein the knob is spring loaded against the nose cone.

2. The anchor delivery tool of claim 1 wherein the knob is slidingly coupled to the hub and proximally located relative to the nose cone.

3. The anchor delivery tool of claim 1 wherein the handle includes at least one suture retaining feature.

4. The anchor delivery tool of claim 3 wherein the suture retaining feature comprises a tab disposed on an outer surface of the handle.

5. The anchor delivery tool of claim 3 wherein the handle includes multiple axially spaced suture retaining features.

6. The anchor delivery tool of claim 1 wherein the handle includes a through passage extending a length of the handle having an opening on an outer surface of the handle at a handle proximal end portion.

7. The anchor delivery tool of claim 1 wherein the knob and an outer surface of the hub define an annular cavity comprising a spring, configured to bias the knob into a cavity of the nose cone.

8. The anchor delivery tool of claim 1 wherein the knob includes laterally extending wings.

9. The anchor delivery tool of claim 1 wherein the nose cone includes a cavity, the cavity housing a distal portion of the knob.

10. The anchor delivery tool of claim 1 wherein the shaft includes an area of reduced diameter.

11. The anchor delivery tool of claim 10 wherein the area of reduced diameter includes a length of about 3 mm.

12. The anchor delivery tool of claim 1 wherein the shaft includes at least two channels extending a length of the shaft.

13. The anchor delivery tool of claim 1 wherein the shaft includes a tip, the tip extending from a distal portion of the shaft.

14. The anchor delivery tool of claim 1 wherein the knob is configured to slide relative to the nose cone, between a suture retaining position wherein a knob distal end is disposed within an inner cavity of the nose cone and abuts an inner cavity surface of the nose cone so as to secure the length of suture disposed therebetween and a suture releasing position wherein the knob distal end is spaced away from an inner cavity surface.

15. An anchor delivery tool comprising:

a shaft and a handle coupled to the shaft, the handle having a hub portion defining a distal portion of the handle, and wherein a nose cone and a knob are disposed around the hub portion, the knob configured to slide axially along the hub portion so as so define a first position wherein a knob distal end is disposed within an inner cavity of the nose cone and abuts an inner cavity surface of the nose cone so as to secure a length of suture therebetween and a second position wherein the knob distal end is spaced away from the inner cavity surface to release the length of suture.

16. The anchor delivery tool of claim 15 wherein the handle includes at least one suture retaining feature disposed on an outer surface of the handle.

17. The anchor delivery tool of claim 16 wherein the handle includes a through passage extending a length of the handle having an opening on an outer surface of a handle proximal end portion, the opening and passage to provide a portion of a suture path from an anchor associated with the anchor delivery tool, the suture path extending along the passage, through the opening and around the at least one suture retaining feature.

18. The anchor delivery tool of claim 15 wherein the knob and hub define an annular cavity, housing a spring disposed around the hub, configured to bias the knob in the first position.

19. The anchor delivery tool of claim 15 wherein the nose cone cavity defines an annular opening at the nose cone proximal end.
