Claim Text:
1. An apparatus for anchoring tissue to bone, comprising: a suture anchor that includes at least one surface feature adapted to engage bone and formed on an external surface thereof along less than an entire longitudinal length of the suture anchor, that includes an inner lumen extending therethrough between proximal and distal ends of the suture anchor, that has opposed cut-outs formed in a sidewall thereof and extending proximally from a distal-most end thereof, and that includes a rotatable member extending across opposed sidewalls of the inner lumen in a distal portion of the suture anchor such that a suture can extend around the rotatable member and trailing ends of the suture can extend through the inner lumen of the suture anchor, the rotatable member being located distal to proximal ends of the opposed cut outs; and a driver having an elongate shaft and a distal end adapted to be advanced distally into a proximal end of the inner lumen so as to engage a proximal portion of the inner lumen of the suture anchor such that after the distal end of the driver has been advanced distally into the proximal end of the inner lumen and the distal end of the driver is engaging the proximal portion of the inner lumen, the driver is adapted to rotate so as to rotate the suture anchor such that the at least one surface feature penetrates into the bone.
