Abstract
A helical fastener having a high retentive surface area is provided and has a first end for enhancing penetration into tissue and a second end comprising a coil sectioning a diameter of the fastener for receiving longitudinal and rotational forces. The helical fasteners are attached to body tissue by a fastener applicator having a proximal portion comprising a handle and an actuator and an elongate distal portion for housing a plurality of fasteners. A transferring action of the actuator provides longitudinal and rotational movement of the fasteners out of the distal portion and into body tissue.
