METHOD AND APPARATUS FOR SURGICAL FASTENING

PROBLEM TO BE SOLVED: To provide a mesh fastener device for repairing hernis which is decomposable and absorbable after treatment is completed.SOLUTION: A surgical fastener system includes a plurality of fasteners 4 having a throughbore with a threaded portion 441. The fasteners may engage with a threaded mandrel that passes through the throughbore of the fasteners. A rotator may rotate the fasteners relative to the mandrel to move at least one of the fasteners along the mandrel, e.g., along the mandrel's longitudinal axis. A distal end of the mandrel may be inserted into a material, such as a tissue, prosthetic, and a fastener may be deployed from the distal end of the mandrel while the distal end is positioned in the material. The throughbore of the fasteners may include a threaded portion and an unthreaded portion, may include an angled face or other feature to aid in fastener deployment and/or have curved depressions in the head portion 41.
