Corkscrew suture anchor and driver

A method of anchoring suture in bone using a spiral-shaped suture anchor having a central axis, a distal end and a proximal end, a sharp point disposed on the distal end of the spiral-shaped suture anchor, and a suture eye disposed on the proximal end of the suture anchor, the method comprising the steps of:

• (a) threading suture through the suture eye on the proximal end of the suture anchor;
• (b) driving the suture anchor under torqued expansion into the bone;
• and
• (c) relaxing the expansion on the suture anchor such that the suture anchor is locked within the bone.

A method of anchoring suture in bone using first and second spiral-shaped suture anchors, each suture anchor having a plurality of screw flights, a central axis, a distal end and a proximal end, a sharp point disposed on the distal end of the spiral-shaped suture anchor, and at least the first suture anchor having a suture eye disposed on the proximal end of the suture anchor, the method comprising the steps of:

• (a) threading suture through the suture eye on the proximal end of the first suture anchor;
• (b) driving the first suture anchor under torqued expansion into the bone at a first position;
• (c) relaxing the expansion on the first suture anchor such that the first suture anchor is locked within the bone at the first position;
• and
• (d) driving the second suture anchor under torqued expansion into the bone at a second position such that at least one of the plurality of screw flights on the second suture anchor interlocks with at least one of the plurality of screw flights on the first suture anchor.
