Abstract

The present disclosure relates to a system for use in tissue repair. The system includes a cannulated guide, an obturator configured for insertion through the guide, a drill configured for insertion through the guide, and an anchor delivery tool configured for insertion through the guide.

First claim

What is claimed is:

1. A system for use in tissue repair comprising:
a cannulated guide;
an obturator configured for insertion through the guide;
a drill configured for insertion through the guide, the drill including a proximal portion, a distal portion, and a flexible portion located between the proximal and distal portions, the drill proximal portion including a depth stop, flat portions, and an area of reduced diameter, the depth stop including flat sides and the area of reduced diameter including a cavity and a laser weld mark spaced away from a distal edge of the area of reduced diameter, the drill distal portion including a sleeve portion and helical threads with a pointed end, and a laser weld mark disposed on a proximal edge of the helical threads and spaced away from a proximal edge of the sleeve portion, ends of the flexible portion extending within and attached to the cavity and the sleeve portion via the laser welds; and
an anchor delivery tool configured for insertion through the guide, the anchor delivery tool including a handle and a shaft coupled to the handle, the shaft including a proximal portion, a distal portion having a smaller diameter than the proximal portion, and a tip extending from the distal portion, the entire tip having a smaller diameter than the distal portion,
wherein the flexible portion has a diameter that is smaller than a diameter of the area of reduced diameter and a diameter of the distal portion of the drill.

2. The system of claim 1 wherein the guide includes a guide handle and a guide shaft coupled to the guide handle.

3. The system of claim 2 wherein the guide shaft includes a distal portion angled relative to a longitudinal axis of the guide shaft.

4. The system of claim 3 wherein the distal portion of the guide shaft includes at least one hole.

5. The system of claim 3 wherein the distal portion of the guide shaft includes a plurality of holes axially spaced along a first side of a guide distal end.

6. The system of claim 3 wherein the distal portion of the guide shaft includes an end having a serrated edge.

7. The system of claim 1 wherein the obturator includes an obturator handle and an obturator shaft coupled to the obturator handle.

8. The system of claim 7 wherein the obturator shaft is a single piece shaft, including a proximal portion having a first length, a portion of reduced diameter extending from the proximal portion having a second length and a distal portion having a diameter different than and extending from the portion of reduced diameter, the second length shorter than the first length.

9. The system of claim 8 wherein the obturator shaft distal portion includes a blunt end.

10. The system of claim 8 wherein the obturator shaft distal portion includes a sharp end.

11. The system of claim 8 wherein the obturator shaft portion of reduced diameter is flexible relative to the obturator shaft proximal portion.

12. The system of claim 8 wherein the portion of reduced diameter is spaced away from the obturator handle by the first length and is substantially closer to a shaft distal terminus than the obturator handle.

13. The system of claim 8 wherein the portion of reduced diameter and the drill flexible portion have substantially similar lengths.

14. The system of claim 1 wherein the shaft has a solid construction throughout.

15. The system of claim 1 wherein the tip is non-cannulated.

16. The system of claim 1 wherein the flexible portion includes an inner layer comprising a plurality of spirally wound metal wires, and an outer layer comprising a plurality of spirally wound metal wires surrounding the inner layer, and a through hole extending the length of the flexible portion.

17. The system of claim 16 wherein the inner and outer layers of spirally wound metal wires of the flexible portion extend within and are coupled to the area of reduced diameter and the sleeve portion of the drill via the laser welds.
