Abstract:
1. A knotless suture anchor comprising: a generally cylindrical, hollow outer member having an axial first lumen, an outer surface, a distal end and a proximal end; an elongated, generally hollow inner member having an axial second lumen being an axially aligned central cavity defined at least in part by a generally cylindrical proximal portion and having a transverse passage defined by a distal portion for receiving suture therethrough, said inner member adapted to move longitudinally within said outer member between a distal, suture-unlocked position and a proximal, suture-locked position; a suture directed along a path distally through said first and second lumens, transversely through said transverse passage, and proximally through said first and second lumens; a suture-locking means situated along said path proximally of said transverse passage, said suture-locking means comprising at least one crimping area interposed between said inner and outer members, said crimping area being normally situated in a suture-unlocked configuration wherein said inner member is situated distally relative to said outer member so said suture is slidable along said path, said crimping area adapted to be activated into a suture-locked configuration upon proximal movement of said inner member relative to said outer member; means for moving said inner member proximally from said suture-unlocked position to said suture-locked position wherein said suture is crimped between said inner and outer members; and means for locking said inner member to said outer member to maintain said inner member in said suture-locked position.
