Abstract

Apparatus and methods for forming pilot holes in bone and deploying a staple therein for fixing a sheet-like implant to the bone. A pilot hole forming trocar assembly including a trocar and a position retention sleeve can be included. The trocar can be releasably coupled to the position retention sleeve and slide in keyed arrangement within the sleeve when uncoupled. The trocar can include a distal portion having a retractable blade and a pair of pilot hole forming spikes extending distally from the trocar shaft. Once the pilot holes are formed, the position retention sleeve maintains the position relative to the pilot holes while the trocar is removed and a staple delivery device can be inserted in the lumen of the position retention sleeve to deploy a staple in the pilot holes.

First claim

What is claimed is:

1 . A system for securing an implant, comprising:
a tubular member having a tubular portion and a lumen extending therein, the tubular member including one or more guide members attached to and extending distally away from the tubular portion; a shaft including a proximal portion and a distal portion, the shaft slidably disposed within the lumen of the tubular member and including one or more pilot hole forming members extending away from a distal end thereof; and a securing member configured to be inserted in one or more pilot holes formed by the one or more pilot hole forming members.

2 . The system of claim 1 , wherein the securing member is configured to be slidably disposed within the lumen of the tubular member.

3 . The system of claim 2 , wherein the shaft is configured to be removed from the tubular member prior to the securing member being inserted into the lumen of the tubular member.

4 . The system of claim 3 , wherein the one or more guide members are configured to be driven into a bone and maintain the position of the tubular member after the shaft has been removed from the tubular member.

5 . The system of claim 4 , wherein the one or more guide members are configured to support the one or more pilot hole forming members as the one or more pilot hole forming members are driven into the bone.

6 . The system of claim 1 , wherein the one or more guide members include a channel having a cross-section, and wherein the cross-section includes a curve.

7 . The system of claim 6 , wherein the channel is configured to mate with the one or more pilot hole forming members, the securing member, or both the one or more pilot hole forming members and the securing member.

8 . The system of claim 1 , wherein the one or more pilot hole forming members extend distal of the one or more guide members.

9 . The system of claim 1 , wherein the one or more pilot hole forming members include a proximal portion and a distal portion, and wherein the pilot hole forming members taper from the proximal portion to the distal portion.

10 . A tendon repair system, comprising:
a tubular member having a tubular portion and a lumen extending therein, the tubular member including one or more guide members extending distally away from the tubular portion; a pilot hole shaft assembly including a shaft and one or more pilot hole forming members, the shaft slidably disposed within the lumen of the tubular member; a staple configured to be inserted in one or more pilot holes formed by the one or more pilot hole forming members; and a handle assembly coupled to the tubular member.

11 . The repair system of claim 10 , wherein the one or more pilot hole forming members extend away from a distal end of the shaft.

12 . The repair system of claim 11 , wherein the one or more pilot hole forming members include a proximal portion and a distal portion, and wherein the one or more pilot hole forming members taper from the proximal portion to the distal portion.

13 . The system of claim 10 , wherein the one or more guide members include a channel having a cross-section, and wherein the cross-section is semi-circular.

14 . The system of claim 13 , wherein the channel of the one or more guide members is configured to mate with the one or more pilot hole forming members, the staple, or both the one or more pilot hole forming members and the staple.

15 . The system of claim 10 , wherein the staple is configured to be slidably disposed within the lumen of the tubular member.

16 . The system of claim 15 , wherein the shaft is configured to be removed from the tubular member prior to the staple being inserted into the lumen of the tubular member.

17 . The system of claim 16 , wherein the one or more guide members are configured to be driven into a bone and maintain the position of the tubular member after the shaft has been removed from the tubular member.

18 . The system of claim 10 , wherein the handle assembly is configured to actuate the pilot hole shaft assembly relative to the tubular member.

19 . The system of claim 18 , wherein the handle assembly is configured to eject the pilot hole shaft assembly from the tubular member.

20 . A system for securing an implant, comprising:
a tubular member having a tubular portion and a lumen extending therein, the tubular member including first and second guide members attached to and extending distally away from the tubular portion; a shaft including a proximal portion and a distal portion, the shaft slidably disposed within the lumen of the tubular member and including first and second pilot hole forming members extending away from a distal end thereof; a staple configured to be inserted in first and second pilot holes formed by the first and second pilot hole forming members; a staple delivery rod configured to drive the staple into a target site; and
a handle assembly coupled to the tubular member.
