<p>A headed bioabsorbable tissue anchor (2) has a continuous thread (6) spiraling around a tapering central core (4). At the distal end, the headed bioabsorbable tissue anchor terminates in a flat point (16). At the proximal end, the bioabsorbable tissue anchor has a flat, disk-shaped head (10) for engaging tissue, and slots (12) formed in the head for engaging a driver (30). The headed bioabsorbable tissue anchor has a large thread surface per turn of thread. As the anchor is turned into bone for engaging cancellous bone, the disk-shaped head (10) engages and anchors the tissue to the bone. <IMAGE></p> |
