1. A tendon anchoring system, comprising:
- an outer shaft having an inner lumen extending therethrough and a sheath alignment protrusion formed on a distal end thereof;
an inner shaft disposed within the outer shaft and having first and second prongs formed on a distal end thereof, the prongs being movable between an extended position in which the prongs extend distally beyond the distal end of the outer shaft, and a retracted position in which the prongs are retracted into the distal end of the outer shaft, the prongs extending along opposed sides of the sheath alignment protrusion on the outer shaft;
a handle assembly coupled to a proximal end of each of the first and second shafts.

5. A method for anchoring a tendon to bone, comprising:
-
manipulating an inserter tool to insert a sheath coupled to a distal end of the inserter tool through tissue, the sheath having a guidewire mated thereto and extending through the inserter tool; positioning a tendon between a pair of prongs on a distal end of the inserter tool, and manipulating the inserter tool to advance the sheath, with the tendon between the prongs, into a bone hole, wherein a locking mechanism on a handle assembly of the inserter tool maintains the guidewire and the prongs in a locked position relative to one another; moving the locking mechanism on the handle assembly to an unlocked position and manipulating the handle assembly to retract the prongs relative to the guidewire; and removing the inserter tool such that the sheath with the guidewire mated thereto remains in the bone hole. - View Dependent Claims (6, 7, 8)
