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.
Claims26
An applicator 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, the proximal portion being attached to the connecting end of the distal portion;
- a plurality of fasteners;
- a thread form contained in an interior of the terminal end adapted to engage the plurality of fasteners;
- and
- a rotator cooperating with the actuator, the rotator including a longitudinal groove extending along at least a portion thereof, the groove configured to receive a portion of at least two fasteners of the plurality of fasteners, wherein the rotator resides within and extends substantially the length of the outer tube such that actuation of the actuator results in rotation and translation of the at least one fastener relative to the outer tube while the rotator remains longitudinally stationary with respect to the outer tube such that actuation of the rotator ejects at least one fastener of the plurality of fasteners from the terminal end.
An applicator comprising:
- an actuator;
- a rotator operatively coupled to the actuator, the rotator having a longitudinal groove;
- a plurality of fasteners disposed about the rotator, each fastener having a portion thereof positioned within the longitudinal groove of the rotator;
- an outer tube surrounding at least a portion of the rotator, wherein actuation of the actuator results in rotation and translation of each fastener of the plurality of fasteners relative to the outer tube and the rotator remains axially stationary with respect to the outer tube and a thread form contained in an interior of a terminal end of the outer tube, the thread form adapted to engage the plurality of fasteners.
