Surgical fasteners

摘要

Surgical fasteners, including tacks are disclosed for fastening a surgical mesh to underlying tissue during surgical procedures to repair body tissue, such as in hernia repair. Such tacks can include a head, a elongated body portion having a distal end and a proximal end, and an anchoring element on an outer surface of the body portion for inhibiting the removal of the tack from the mesh and body tissue.
