Suture anchor and associated method of implantation

A kit for anchoring a suture in a bore in a bone, said kit comprising:

• at least one suture anchor for wedging within the bore and comprising:
• a non-conical body having a generally quadrilaterally shaped lateral cross-section, said body further having a bore-abutting surface having opposed ends and at least one gripping edge, the bore-abutting surface being adapted to abut a wall defining the bore upon insertion of the suture anchor into the bore;
• said body further defining:
• a suture bore extending transversely therethrough;
• and
• a non-circular inserter bore adapted to receive an insertion tool and disposed between the at least one gripping edge and the suture bore;
• at least one suture operably engaged with the suture bore, the suture passing through the suture bore and adapted to engage bodily tissue to be secured to the bone;
• and
• at least one insertion device for minimizing rotation of a suture anchor with respect to the insertion device and for implanting the suture anchor in the bore in the bone, comprising:
• a rigid shaft having opposed ends;
• and
• a tip at one end of said shaft, the tip being comprised of a shape memory material and having a proximal end operably engaged with the shaft and a free distal end capable of engagement with the inserter bore, the distal end of the tip having a non-circular cross-section corresponding to the non-circular cross-section of the inserter bore so as to minimize rotation of the suture anchor about the axis of the tip when the distal end of the tip is engaged with the inserter bore.
