Abstract
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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
100 words
A system for applying fasteners to body tissue, comprising: a plurality of fasteners, each having a helical configuration; an applicator for applying said fasteners to body tissue, said applicator having a distal portion and a proximal portion; said distal portion having an elongate outer tube, a connecting end and a terminal end, said terminal end having internal threads; said proximal portion having a handle and an actuator, said proximal portion attached to said connecting end of said distal portion; and said plurality of fasteners being configured within said distal portion and advanced through said threads upon manipulation of said actuator.
Claim 2
Independent Claim
100 words
A system for applying fasteners to body tissue, comprising: a plurality of fasteners, each having a helical configuration; an applicator for applying said fasteners to body tissue, said applicator having a distal portion and a proximal portion; said distal portion having an elongate outer tube, a connecting end and a terminal end, said terminal end having internal threads; said proximal portion having a handle and an actuator, said proximal portion attached to said connecting end of said distal portion; and said plurality of fasteners being configured within said distal portion and advanced through said threads upon manipulation of said actuator.
Claim 3
Dependent Claim
17 words
The system of claim 1, wherein said threads are formed within interior walls of said outer tube.
Claim 4
Dependent Claim
24 words
The system of claim 1, wherein said distal portion further comprises a sleeve attached to said outer tube, said sleeve defining said internal threads.
Claim 5
Dependent Claim
19 words
The system of claim 1, wherein said threads are formed by deforming said terminal end of said outer tube.
Claim 6
Dependent Claim
32 words
The system of claim 1, wherein each said fastener defines a plurality of adjacent coils, at least one of said fasteners having said adjacent coils configured within threads of said terminal end.
Claim 7
Dependent Claim
16 words
The system of claim 1, wherein said threads guide said fasteners out of said distal portion.
Claim 8
Dependent Claim
39 words
The system of claim 1, said applicator further comprising a rotator for receiving said plurality of fasteners and for cooperating with said actuator, wherein upon rotation of said rotator, said fasteners advance through said distal portion and said threads.
Claim 9
Dependent Claim
18 words
The system of claim 1, wherein upon manipulation of said actuator, said fasteners are rotated through said threads.
Claim 10
Dependent Claim
21 words
The system of claim 1, wherein said threads define the pitch of said fasteners as said fasteners exit said distal portion.
