Anchor delivery system
An anchor delivery system is described. The system includes a guide and an anchor delivery tool disposed within the guide. The tool includes a shaft and a handle coupled to a proximal portion of the shaft. The handle includes a hub and a nose cone coupled to the hub. In an embodiment, the tool further includes a knob coupled to the hub and located between the handle and the nose cone. In an embodiment, the system further includes an anchor, such as a suture anchor, coupled to a distal portion of the shaft. An anchor delivery tool and a method of repairing soft tissue are also described.
1. An anchor delivery system comprising:
a guide; and
an anchor delivery tool disposed within the guide, the tool including a shaft and a handle coupled to the shaft comprising a handle portion monolithically coupled to a hub portion and a nose cone coupled to the hub, the hub disposed within a bore of the nose cone, the shaft including a suture anchor coupled to a distal end of the shaft, suture extending along lengths of the anchor and the shaft and through a proximal portion of the anchor, the handle portion including suture retaining tabs and the nose cone including a slotted opening, ends of the suture retained by the tabs and the slotted opening, wherein the hub portion terminates proximal to the distal end of the shaft.
2. The anchor delivery system of claim 1 further comprising a knob coupled to the hub and located between the handle and the nose cone.
3. The anchor delivery system of claim 1 wherein a shaft of the guide is bent relative to a longitudinal axis of the guide.
4. The anchor delivery system of claim 1 wherein the guide comprises a high strength material.
5. An anchor delivery tool comprising:
a shaft and a handle coupled to the shaft comprising a handle portion monolithically coupled to a hub portion and a nose cone coupled to the hub, the hub disposed within a bore of the nose cone, the shaft including a suture anchor coupled to a distal end of the shaft, suture extending along lengths of the anchor and the shaft and through a proximal portion of the anchor, the handle portion including suture retaining tabs and the nose cone including a slotted opening, ends of the suture retained by the tabs and the slotted opening, wherein the hub portion terminates proximal to the distal end of the shaft.
6. The anchor delivery tool of claim 5 further comprising a knob coupled to the hub and located between the handle and the nose cone.
7. The anchor delivery tool of claim 6 wherein the knob is movable between a first position and a second position with respect to the nose cone.
8. The anchor delivery tool of claim 6 wherein the knob is spring loaded against the nose cone.
9. The anchor delivery tool of claim 6 wherein the knob includes laterally extending wings.
10. The anchor delivery tool of claim 6 wherein the nose cone includes a cavity, the cavity housing a distal portion of the knob when the knob is in a first position.
11. The anchor delivery tool of claim 5 wherein the handle includes a through passage extending a length of the handle.
12. The anchor delivery tool of claim 5 wherein the shaft includes an area of reduced diameter.
13. The anchor delivery tool of claim 12 wherein the area of reduced diameter includes a length of about 3 mm.
14. The anchor delivery tool of claim 5 wherein the shaft includes at least two channels extending a length of the shaft.
15. The anchor delivery tool of claim 5 wherein the shaft includes a tip, the tip extending from a distal portion of the shaft.
16. An anchor delivery tool comprising:
a shaft, a handle coupled to the shaft comprising a handle portion monolithically coupled to a hub portion, and a nose cone coupled to a hub of the handle, the hub disposed within a bore of the nose cone, the shaft including a suture anchor coupled to a distal end of the shaft, suture extending along lengths of the anchor and the shaft and through a proximal portion of the anchor, the handle portion including suture retaining tabs and the nose cone including a slotted opening, ends of the suture retained by the tabs and the slotted opening, wherein the hub portion terminates proximal to the distal end of the shaft.
17. The anchor delivery tool of claim 16 further comprising a knob coupled to the hub and located between the handle and the nose cone.
18. The anchor delivery tool of claim 17 wherein the knob is movable between a first position and a second position with respect to the nose cone.
19. The anchor delivery tool of claim 17 wherein the nose cone includes a cavity, the cavity housing a distal portion of the knob when the knob is in a first position.
20. The anchor delivery tool of claim 16 wherein the shaft includes a tip, the tip extending from a distal portion of the shaft.
21. An anchor delivery tool comprising:
a shaft and a handle coupled to the shaft comprising a handle portion monolithically coupled to a hub portion, a nose cone coupled to the hub, the hub disposed within a bore of the nose cone, the shaft including a suture anchor coupled to a distal end of the shaft, suture extending along lengths of the anchor and the shaft and through a proximal portion of the handle, the handle portion including suture retaining tabs located on an outer surface of the handle portion.
22. The anchor delivery tool of claim 21 further comprising the nose cone including a slotted opening, ends of the suture retained by the slotted opening.
23. The anchor delivery tool of claim 21 wherein ends of the suture are retained by a slotted opening on the nose cone.
