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.
Claims20
An applicator for attaching fasteners to body tissue comprising:
- a distal portion having an elongate outer tube, a connecting end and a terminal end;
- a proximal portion having a handle and an actuator, said proximal portion attached to said connecting end of said distal portion;
- a rotator for receiving a plurality of fasteners and for cooperating with said actuator, said rotator configured to reside within and extend substantially the length of said outer tube;
- means for threading and ejecting the fastener out of said terminal end;
- and a load spring for biasing said plurality of fasteners to the terminal end.
