Abstract

Methods and devices are provided for anchoring a ligament or tendon to bone. In one embodiment, a surgical implant is provided having a sheath and an expander that is received within the sheath. Various delivery tools, including a sheath inserter and a driver, are also provided. In use, the sheath inserter can be used to position a tendon within a prepared bone hole, and it can be used to deliver the sheath with a guidewire coupled thereto into the bone hole. The driver can be provided for delivering the expander into the sheath. A loader can optionally be used to load the driver and expander onto the guidewire coupled to the implanted sheath.

First claim

What is claimed is:

1. An anchor driver tool, comprising:
an outer shaft having first and second prongs extending distally from a distal end thereof and configured to extend into opposed slots formed in a sheath of an anchor assembly;
an inner shaft extending through the outer shaft and having a distal end configured to mate with an expander of an anchor assembly; and
a handle assembly having a proximal handle fixedly mated to a proximal end of the inner shaft and a distal handle coupled to a proximal end of the outer shaft, the proximal handle being positioned proximal of the distal handle such that the inner shaft extends into a proximal end of the distal handle and extends distally from the distal handle, the distal handle including first and second alignment indicators configured to indicate a position of the first and second prongs, wherein rotation of the proximal handle causes corresponding rotating of the inner shaft relative to the outer shaft for driving an expander configured to be coupled to a distal end of the inner shaft into a sheath configured to be coupled to the first and second prongs of the outer shaft, the outer shaft being configured to hold the sheath in a substantially fixed position during rotation of the inner shaft.

2. The anchor driver tool of claim 1 , wherein the outer shaft includes opposed viewing windows formed in a distal portion thereof.

3. The anchor driver tool of claim 1 , wherein the outer shaft includes opposed cut-outs formed in the distal end thereof for seating a graft.

4. The anchor driver tool of claim 1 , wherein the outer shaft is freely rotatably movable relative to the inner shaft, and axial translation of the outer shaft relative to the inner shaft is limited to a predetermined distance.

5. The anchor driver tool of claim 1 , further comprising at least one marking formed on at least one of the inner and outer shafts for indicating when the expander is fully seated within the sheath.
