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: 21
Claim 1
Independent Claim
100 words
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.
Claim 2
Dependent Claim
100 words
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.
Claim 3
Dependent Claim
28 words
The applicator of claim 1, further comprising: a lock/clip indicator for engaging said plurality of fasteners; and said load spring for applying longitudinal forces against said lock/clip indicator.
Claim 4
Dependent Claim
27 words
The applicator of claim 2, wherein said lock/clip indicator is configured to prevent actuation of said actuator upon discharge of said plurality of fasteners from the applicator.
Claim 5
Dependent Claim
27 words
The applicator of claim 1, wherein a groove extends longitudinally along substantially the length of said rotator, said groove for recieving coils of said plurality of fasteners.
Claim 6
Dependent Claim
26 words
The applicator of claim 1, wherein said rotator has a cross-sectional profile approximating a D-shape and is adapted to receive coils of said plurality of fasteners.
Claim 7
Dependent Claim
30 words
The applicator of claim 1, wherein said threading and ejecting means is a thread form contained in an interior of said terminal end adapted to engage said plurality of fasteners.
Claim 8
Dependent Claim
22 words
The applicator of claim 6, wherein said thread form is an interlock spring fixedly retained in said interior of said terminal end.
Claim 9
Dependent Claim
43 words
The applicator of claim 1, wherein said threading and ejecting means is a nose piece attached to said terminal end, said nose piece having structure projecting perpendicularly toward a longitudinal axis of said outer tube and adapted to engage said plurality of fasteners.
Claim 10
Dependent Claim
17 words
The applicator of claim 1, wherein said distal portion and said proximal portion are releasably secured together.
Claim 11
Dependent Claim
17 words
The applicator of claim 9, wherein said distal portion is disposable and said proximal portion is reusable.
Claim 12
Dependent Claim
114 words
The applicator of claim 1, wherein said actuator includes: a lever having a first end and a second end, said lever pivotally attached about a midpoint to said handle; said first end of said lever for gripping by hand; a lead screw rotatably attached to interior of said handle; a nut driver, said second end of said lever pivotally attached to said nut driver, said nut driver for travelling along said lead screw, thereby turning said lead screw; and said lead screw attached to said rotator so that as the lever is depressed by hand the nut driver will travel along the lead screw towards said rotator thereby turning said rotator in the process.
Claim 13
Dependent Claim
15 words
The applicator of claim 11, wherein said lead screw is a high helix lead screw.
Claim 14
Dependent Claim
12 words
The applicator of claim 11, wherein said lever has a midsection extension.
Claim 15
Dependent Claim
16 words
The applicator of claim 13, further comprising gear teeth formed within said interior of said handle.
Claim 16
Dependent Claim
24 words
The applicator of claim 14, further comprising a spring loaded pawl pivotally attached to said midsection extension and adapted to engage said gear teeth.
Claim 17
Dependent Claim
140 words
The applicator of claim 1, wherein said actuator includes: a lever having a first end, a midsection, and a second end, said first end pivotally attached to said handle, said midsection for gripping by hand; a lead screw rotatably attached to an interior of said handle; a nut driver, said second end pivotally attached to said nut driver, said nut driver for travelling along said lead screw, thereby turning said lead screw; and means for said lead screw to releasably engage said rotator so that as the lever is depressed by hand, the nut driver will travel along the lead screw toward said rotator thereby turning said rotator in the process and so that when the lever is returned to its undepressed position, the lead screw will rotate in the reverse direction and independently of the rotator which remains stationary.
Claim 18
Dependent Claim
15 words
The applicator of claim 16, wherein said lead screw is a high helix lead screw.
Claim 19
Dependent Claim
14 words
The applicator of claim 16, wherein said releasable engagement means is a ratchet mechanism.
Claim 20
Dependent Claim
22 words
The applicator of claim 16, wherein said lever has a mid-section extension, formed in said mid-section extension are a plurality of teeth.
Claim 21
Dependent Claim
26 words
The application of claim 19, further comprising a latch pawl cooperating with said teeth to prohibit said lever from backstroking until it has been completely depressed.
