Abstract
Abstract A self-closing receiverless surgical fastener comprises a fastener body of biocompatible or bioabsorbable material including a bridge member and at least two tines extending from opposite ends of the bridge member. The tines are resiliently deformable from a normally closed position with the distal ends of the tines pointing toward each other to an open position with the distal ends of the tines extending substantially parallel to each other for penetrating into tissue. The tines are resiliently returnable to the closed position with the distal ends of the tines pointing toward each other to secure the fastener body to the tissue.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
106 words
A surgical fastener, comprising: a fastener body including a bridge member and at least two tines extending from opposite ends of said bridge member, said tines each having a distal end for penetrating tissue; said tines being resiliently deformable from a normally closed position with said distal ends of said tines pointing toward each other to an open position with said distal ends of said tines extending substantially parallel to each other for penetrating into the tissue; and said tines being resiliently returnable to said closed position with said distal ends of said tines pointing toward each other to secure said fastener body to the tissue.
Claim 2
Dependent Claim
106 words
A surgical fastener, comprising: a fastener body including a bridge member and at least two tines extending from opposite ends of said bridge member, said tines each having a distal end for penetrating tissue; said tines being resiliently deformable from a normally closed position with said distal ends of said tines pointing toward each other to an open position with said distal ends of said tines extending substantially parallel to each other for penetrating into the tissue; and said tines being resiliently returnable to said closed position with said distal ends of said tines pointing toward each other to secure said fastener body to the tissue.
Claim 3
Dependent Claim
14 words
The surgical fastener of claim 1, wherein: said fastener body consists of resilient material.
Claim 4
Dependent Claim
14 words
The surgical fastener of claim 1, wherein: said fastener body consists of biocompatible material.
Claim 5
Dependent Claim
14 words
The surgical fastener of claim 1, wherein: said fastener body consists of bioabsorbable material.
Claim 6
Dependent Claim
29 words
The surgical fastener of claim 1, wherein: each of said tines has a resilient hinge-like section which normally maintains said distal ends of said tines pointing toward each other.
Claim 7
Dependent Claim
37 words
The surgical fastener of claim 5, wherein: said resilient hinge-like sections permit said distal ends of said tines to pivot from a closed position pointing toward each other to an open position substantially parallel to each other.
Claim 8
Dependent Claim
33 words
The surgical fastener of claim 5, wherein: each tine has a tab adjacent to said hinge-like section which projects laterally outward when said distal ends of said tines are pointing toward each other.
Claim 9
Dependent Claim
26 words
The surgical fastener of claim 5, wherein: a portion of each tine is removed adjacent to said hinge-like section to enhance the resiliency of said tines.
Claim 10
Dependent Claim
23 words
The surgical fastener of claim 1, wherein: said bridge member is curved in shape and extends between the proximal ends of said tines.
Claim 11
Dependent Claim
37 words
The surgical fastener of claim 1, wherein: said bridge member is reduced in thickness compared with said tines for slidably receiving an actuator between said tines to apply pressure to pivot said distal ends of said tines.
Claim 12
Dependent Claim
40 words
The surgical fastener of claim 1, wherein said bridge member comprises: a pair of bridge members arranged side by side and spaced apart for slidably receiving an actuator therebetween to apply pressure to pivot said distal ends of said tines.
Claim 13
Dependent Claim
100 words
A surgical fastener, comprising: a fastener body including a bridge member and at least two tines extending in the same direction from opposite ends of said bridge member; said tines including proximal portions extending substantially parallel to each other from said bridge member and distal portions extending transversely from said proximal portions and pointing toward each other; said distal portions of said tines being movable in response to pressure to a substantially parallel orientation to each other, and said distal portions of said tines being resiliently returnable to a transverse orientation pointing toward each other when said pressure is released.
Claim 14
Dependent Claim
100 words
A surgical fastener, comprising: a fastener body including a bridge member and at least two tines extending in the same direction from opposite ends of said bridge member; said tines including proximal portions extending substantially parallel to each other from said bridge member and distal portions extending transversely from said proximal portions and pointing toward each other; said distal portions of said tines being movable in response to pressure to a substantially parallel orientation to each other, and said distal portions of said tines being resiliently returnable to a transverse orientation pointing toward each other when said pressure is released.
Claim 15
Dependent Claim
14 words
The surgical fastener of claim 12, wherein: said fastener body consists of resilient material.
Claim 16
Dependent Claim
14 words
The surgical fastener of claim 12, wherein: said fastener body consists of biocompatible material.
Claim 17
Dependent Claim
14 words
The surgical fastener of claim 12, wherein: said fastener body consists of bioabsorbable material.
Claim 18
Dependent Claim
29 words
The surgical fastener of claim 12, wherein: each of said tines has a resilient hinge-like section which normally maintains said distal ends of said tines pointing toward each other.
Claim 19
Dependent Claim
37 words
The surgical fastener of claim 16, wherein: said resilient hinge-like sections permit said distal ends of said tines to pivot from a closed position pointing toward each other to an open position substantially parallel to each other.
Claim 20
Dependent Claim
33 words
The surgical fastener of claim 16, wherein: each tine has a tab adjacent to said hinge-like section which projects laterally outward when said distal ends of said tines are pointing toward each other.
Claim 21
Dependent Claim
26 words
The surgical fastener of claim 16, wherein: a portion of each tine is removed adjacent to said hinge-like section to enhance the resiliency of said tines.
Claim 22
Dependent Claim
23 words
The surgical fastener of claim 12, wherein: said bridge member is curved in shape and extends between the proximal ends of said tines.
Claim 23
Dependent Claim
37 words
The surgical fastener of claim 12, wherein: said bridge member is reduced in thickness compared with said tines for slidably receiving an actuator between said tines to apply pressure to pivot said distal ends of said tines.
Claim 24
Dependent Claim
