Tenodesis anchoring systems and tools
First Claim
1. A bone anchoring system, comprising:
- a sheath having a first sidewall with proximal and distal ends and a second sidewall with proximal and distal ends, 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, wherein the proximal ends of the first and second sidewalls are configured to be spaced away from one another when the sheath is in an implanted configuration; and
an elongate shaft having a distal end with a distally-extending central protrusion that extends into the sheath between the first and second sidewalls, and the distal end having at least first and second distally-extending side protrusions positioned on opposite sides of the central protrusion and extending along opposite outer sides of the first and second sidewalls such that the first and second distally-extending side protrusions prevent rotation of the first and second sidewalls about the hinge pin.

Abstract
Systems and tools are provided for anchoring a ligament or tendon to bone. In one embodiment, a sheath is provided having a first sidewall with proximal and distal ends and a second sidewall with proximal and distal ends. The distal ends of the first and second sidewalls can be coupled to one another by a hinge pin such that the first and second sidewalls pivot relative to one another about the hinge pin. A sheath inserter tool is also provided and it can be configured to couple to the sheath and to advance the expandable sheath, with a tendon disposed therearound, into a bone hole. An expander is also provided for expanding the sheath. In this way, a tendon or ligament is delivered into the bone hole and the sheath and tendon are locked within the bone hole.
