Abstract
Abstract A two-part fastener for use in septoplasty procedures includes a fastener portion having a base with shaft extending perpendicularly therefrom and a retainer having an aperture for engagement with the shaft. The fastener may include indexing means for positioning the retainer in engagement with the fastener portion at discrete spaced apart locations along the shaft. In another embodiment the shaft is slightly larger in diameter than the aperture in the retainer to effect a frictional engagement. Applicator instruments are also provided. In one embodiment the applicator includes two elongated members pivotally connected in the middle. In another embodiment the applicator includes an elongated body which holds a plurality of septoplasty fasteners. A pivotally connected lower jaw holds a supply of retainers. A pusher member drives the fastener through a curved firing chamber, through body tissue, and into engagement with the retainer.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
139 words
A fastener for use in nasal reconstructive surgery, which comprises: a) a fastener portion which includes a crosspiece having a distal surface and a proximal surface, a shaft integral with said cross-piece and extending distally from said distal surface, said shaft having a plurality of flat surface portions, said fastener portion having a bore extending through said crosspiece and axially through the lengthwise extension of said shaft; b) a resilient and flexible retainer portion having an aperture for receiving said shaft, said aperture being shaped so as to accommodate said flat surface portions of said shaft to prevent rotation of said fastener portion relative to said retainer portion when said fastener portion and retainer portion are mutually engaged; and c) indexing means on said fastener for positioning engagement of said fastener portion at discrete spatial intervals along said shaft.
Claim 2
Dependent Claim
139 words
A fastener for use in nasal reconstructive surgery, which comprises: a) a fastener portion which includes a crosspiece having a distal surface and a proximal surface, a shaft integral with said cross-piece and extending distally from said distal surface, said shaft having a plurality of flat surface portions, said fastener portion having a bore extending through said crosspiece and axially through the lengthwise extension of said shaft; b) a resilient and flexible retainer portion having an aperture for receiving said shaft, said aperture being shaped so as to accommodate said flat surface portions of said shaft to prevent rotation of said fastener portion relative to said retainer portion when said fastener portion and retainer portion are mutually engaged; and c) indexing means on said fastener for positioning engagement of said fastener portion at discrete spatial intervals along said shaft.
Claim 3
Dependent Claim
14 words
The fastener of claim 1 wherein said fastener is fabricated from a bioabsorbable material.
Claim 4
Dependent Claim
33 words
The fastener of claim 2 wherein said bioabsorbable material comprises a synthetic polymer selected from the group consisting of polymers of glycolide, lactide, p-dioxanone, caprolactone, trimethylene carbonate, and physical and chemical combinations thereof.
Claim 5
Dependent Claim
15 words
The fastener of claim 1 wherein said distal surface of said crosspiece is substantially flat.
Claim 6
Dependent Claim
14 words
The fastener of claim 1 wherein said proximal surface of said crosspiece is curved.
Claim 7
Dependent Claim
59 words
The fastener of claim 1 wherein said indexing means comprises a plurality of spaced apart ridges, each ridge including an inclined distal surface and a proximal abutment surface, and wherein said aperture of said retainer has a diameter about 1% to about 20% less than the cross sectional diameter of the shaft at the widest portion of the ridge.
Claim 8
Dependent Claim
38 words
The fastener of claim 6 wherein said retainer aperture is resiliently deformable to permit passage therethrough of the shaft and ridges upon application of a force of suitable magnitude and direction to the fastener portion and/or retainer portion.
Claim 9
Dependent Claim
15 words
The fastener of claim 1 wherein said shaft has an axial centerline which is curved.
Claim 10
Dependent Claim
26 words
The fastener of claim 8 wherein the curvature of said axial centerline is defined by a radius of from about 0.25 inches to about 0.40 inches.
