US 2017/0290656 A1 · Tenodesis Anchoring Systems and Tools

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.

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;
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.
