Patent Images
1. A system for controllably discharging fasteners from an applicator, comprising:
- a plurality of fasteners, said fasteners having a helical configuration;
an applicator for attaching said fasteners to tissue, said applicator including a proximal portion, a distal portion and an actuator assembly;
said distal portion having an elongate outer tube, a connecting end and a terminal end;
a proximal portion having a handle, said proximal portion attached to said connecting end of said distal portion; and
said actuator assembly including a lever and configured to controllably discharge one of said plurality of fasteners from said distal portion upon complete depression of said lever and to prohibit backstroking of said lever where is partially depressed.

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.
