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.
Claims15
A fastener for ligating tissue or for attaching an implantable device, the fastener comprising:
- a continuous helical coil having a distal end, a proximal end and a diameter, said distal end having a first terminal coil and said proximal end having a second terminal coil;
- said first terminal coil forming a point for piercing tissue;
- said first terminal coil having a first helical coil section adjacent said distal end where there is a gap between said point and said first helical coil section;
- and
- said second terminal coil configured into a T-bar, said T-bar perpendicularly extending along said diameter of the fastener over less than the entire length of the diameter.
An apparatus for use in surgical procedures, comprising:
- a fastener having a continuous substantially helical configuration, a circular cross-sectional profile, a distal portion and a proximal portion;
- said proximal portion including a first coil section and a first terminal end, said first terminal end departing from said continuous helical configuration of said fastener by being configured to substantially perpendiculurly section said circular cross-sectional profile of said fastener, said first terminal end terminating with a blunt tip, wherein said first terminal end and said blunt tip reside in a plane occupied by said first coil section;
- and
- said distal portion including a second terminal end which exists in a space set longitudinally apart from said first terminal end, said second terminal end being configured with a sharp point.
