| abstract |
A helical fastener (10) having a high retentive surface area is provided and has a first end (22) for enhancing penetration into tissue (25) and a second end (26) comprising a coil sectioning a diameter (18) of the fastener (10) for receiving longitudinal and rotational forces. The helical fasteners (10) are attached to body tissue (25) by a fastener applicator (12) having a proximal portion (28) comprising a handle (30) and an actuator (32) and an elongate distal portion (34) for housing a plurality of fasteners (10). A transferring action of the actuator (32) provides longitudinal and rotational movement of the fasteners (10) out of the distal portion (34) and into body tissue (25). |
