Suture anchoring device and method

摘要

A suture anchor includes a rivet for insertion into a predrilled bore hole in bone, and a setting pin which extends through an axial aperture in the rivet. Preferably the setting pin has barbed legs which are radially expandable to frictionally engage the walls of the bore hole to secure the anchor therein. The setting pin includes a suture accommodating aperture, surface, and/or slot. In one embodiment, a snap-fitting detent and notch are engageable with each other to form an escapement mechanism to position the setting pin at discrete positions within the axial aperture of the rivet.
