Tenodesis implants and tools
First Claim
1. An anchor assembly, comprising:
- a sheath having a first sidewall and a second sidewall each with proximal and distal ends and a boss formed on the proximal end of each of the first and second sidewalls, the distal ends of the first and second sidewalls being coupled to one another by a hinge pin such that the first and second sidewalls pivot relative to one another about the hinge pin; and
an expander having a generally elongate cylindrical configuration and configured to be received between the first and second sidewalls of the sheath to cause the first and second sidewalls to pivot about the hinge pin and move laterally away from one another, wherein the boss on each sidewall extends toward the other one of the first and second sidewalls such that the proximal ends of the first and second sidewalls substantially circumferentially surround the expander.

Abstract
Methods and devices are provided for anchoring a ligament or tendon to bone. In one embodiment, a biceps tenodesis system is provided and includes a sheath inserter tool, an expandable sheath configured to couple to the sheath inserter tool, an expander inserter tool, and an expander configured to couple to the expander inserter tool. The sheath inserter tool is configured to advance the expandable sheath, with a tendon disposed therearound, into a bone hole, and the expander inserter tool is configured to advance the expander through an outer shaft of the sheath inserter tool and to drive the expander into the sheath. The expander is configured to be received within a lumen extending at least partially through the expandable sheath to thereby expand the sheath. In this way, the system delivers the tendon or ligament into the bone hole and locks the sheath and tendon within the bone hole.
