Abstract
A helicoil interference fixation system comprising: a helicoil comprising a helical body comprising a plurality of turns separated by spaces therebetween, the helical body terminating in a proximal end and a distal end, and at least one internal strut extending between at least two turns of the helical body; and an inserter for turning the helicoil, the inserter comprising at least one groove for receiving the at least one strut; the helicoil being mounted on the inserter such that the at least one strut of the helicoil is mounted in the at least one groove of the inserter, such that rotation of the inserter causes rotation of the helicoil.

1-32. (canceled)
A device comprising:
- an anchor including:
- a helicoil portion having a plurality of coils defining openings between adjacent coils and at least one drive surface extending longitudinally along at least a portion of the helicoil portion and interconnecting at least two of the coils, the at least one drive surface occupying less than 50% of the openings between the coils;
- and
- a distal portion connected to the helicoil portion;
- and
- an inserter adapted to couple with the anchor for insertion of the anchor.
A device comprising:
- an anchor including:
- a helicoil portion having at least one helical thread defining openings between adjacent turns and at least one drive surface extending longitudinally along at least a portion of the helicoil portion and interconnecting at least two of the turns, the at least one helical thread lacking any root between the turns of the thread when defining openings between adjacent turns;
- and
- a distal portion connected to the helicoil portion;
- and
- an inserter adapted to couple with the anchor for insertion of the anchor.
