Abstract
Abstract A surgical device is provided for anchoring suture into bone. The device includes a threaded portion having rounded exterior thread edges. An aperture for carrying suture passes through the threaded portion at a location intermediate the ends of the threaded position, the aperture extending in a direction substantially transversely to the longitudinal axis of the device. When the device is inserted within a cavity in the bone having a threaded sidewall, the suture is compressed between the threads of the device and the sidewall.

A process for anchoring suture into bone, comprising: forming a cavity within the bone having a compacted sidewall; threading the sidewall of the cavity; and inserting a threaded portion of a suture anchor within the cavity, said portion including threads with rounded exterior edges and having an exterior diameter less than that of the threaded sidewall, said anchor further including an aperture passing through the anchor in a substantially transverse direction to a longitudinal axis of the anchor and at a location intermediate the ends of the threaded portion, said aperture receiving a length of suture having ends projecting from the aperture which are compressed between the threads of the anchor and the sidewall when said anchor is inserted within the cavity.
