Abstract

A self-threading suture anchor assembly and kit includes a suture anchor having an anchor portion at one end and a drive portion with an eyelet at an opposite end, and an elongated suture threading loop with an elongated, substantially rigid gripping member attached thereto. The threading loop is collapsible, yet it maintains a loop shape. The elongated gripping member acts as a wand for manipulation of the loop. Both the threading loop and the elongated gripping member are adapted to be encased in a removable elongated sheath which extends beyond the ends of the loop and gripping member. The assembly is inserted into a cannulated shaft of a rotatable driver which includes a bone-cutting drive bit adapted for gripping the suture anchor at its drive end and for cutting into bone. The distal portion of the elongated sheath extends through a port in the shaft and is frictionally engageable with the shaft by means of an annular retaining element slidably disposed on the shaft. Removal of the driver from the anchor after installation of the anchor in a bone effects simultaneous removal of the elongated sheath from the threading loop and gripping member, which, when exposed, permit threading of a suture or section of tendon or other soft tissue through the eyelet of the suture anchor.
