International ClassA61B 017/04AbstractA bioabsorbable soft tissue anchor system comprising a cannulated soft tissue anchor for being turned through soft tissue, and a driver for driving the anchor and method for attaching soft tissue at a selected site of implantation. The soft tissue anchor is an elongated unitary body having a threaded distal section, a non-threaded proximal section, a transverse proximal head and a non-circular axial throughbore. The threaded section has a cancellous-type thread which has a uniform minor diameter, a large pitch and a large major diameter, the distal end of the thread being tapered toward the distal end of the anchor. The proximal end of the threaded section abuts the non-threaded section which is tapered and extends proximally to the transverse head. The anchor is used with a driver having a driving shaft with a pointed tip and a cross-section adapted to engage the anchor's axial throughbore. The driving shaft is longer than the anchor so that the anchor may be placed on the shaft leaving the tip exposed to permit tissue to be pierced and placed adjacent a pre-formed hole at the site of implantation. Simultaneous pushing and turning of the driver will then advance the anchor through the tissue and into the pre-formed hole.Other References
