At the distal end, the headed bioabsorbable tissue anchor terminates in a flat point. At the proximal end, the bioabsorbable tissue anchor has a flat, disk-shaped head for engaging tissue, and slots formed in the head for engaging a driver. The anchor also has a cannula shaped to engage the driver. 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 engages and anchors the tissue to the bone.Other References
