Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
206 words
A surgical fastener for closure of Y-shaped incisions, comprising: a unitary body having a base member wherein said base member is Y-shaped and defines a plane, and piercing means for piercing and engaging body tissue, said piercing means including at least three legs, each leg extending from said base member, said legs each having a bendable hinge region and a tissue piercing point for engaging said body tissue by bending from a first position to a second position so as to present a tissue abutment surface to prevent withdrawal of the surgical fastener, and said legs each further having a proximal surface for receiving a distally directed applying force, said legs being bendable from said first position to said second position in response to application of said applying force thereto where said position is at an angle to said plane of said base, wherein said positions are stable in the absence of external forces, and wherein each of said legs has a first portion and a second portion, said first portion having a first end and a second end, said second portion having a third end and a fourth end, said first end extending from said base member, said third end extending from said second end.
Claim 2
Dependent Claim
206 words
A surgical fastener for closure of Y-shaped incisions, comprising: a unitary body having a base member wherein said base member is Y-shaped and defines a plane, and piercing means for piercing and engaging body tissue, said piercing means including at least three legs, each leg extending from said base member, said legs each having a bendable hinge region and a tissue piercing point for engaging said body tissue by bending from a first position to a second position so as to present a tissue abutment surface to prevent withdrawal of the surgical fastener, and said legs each further having a proximal surface for receiving a distally directed applying force, said legs being bendable from said first position to said second position in response to application of said applying force thereto where said position is at an angle to said plane of said base, wherein said positions are stable in the absence of external forces, and wherein each of said legs has a first portion and a second portion, said first portion having a first end and a second end, said second portion having a third end and a fourth end, said first end extending from said base member, said third end extending from said second end.
Claim 3
Dependent Claim
29 words
The surgical fastener of claim 1, wherein each of said leg first portions forms an angle with said base member ranging from about 150 degrees to about 180 degrees.
Claim 4
Dependent Claim
17 words
The surgical fastener of claim 1, wherein said leg first portions are coplanar with said base member.
Claim 5
Dependent Claim
19 words
The surgical fastener of claim 1, wherein said leg first portions are substantially perpendicular to said leg second portions.
Claim 6
Dependent Claim
15 words
The surgical fastener of claim 1, wherein said fastener is formed from metal or polymer.
Claim 7
Dependent Claim
15 words
The surgical fastener of claim 1, wherein said fastener is formed from a bioabsorbable polymer.
Claim 8
Dependent Claim
44 words
The surgical fastener of claim 1, wherein said leg is bendable at a hinge region, said first end of said first leg portion and said base member form said hinge region and said first portion of said leg is bendable about said hinge region.
Claim 9
Dependent Claim
152 words
A surgical fastener for closure of a Y-shaped incision, which comprises: a unitary body having a) a base portion which includes three rectilinear members connected to each other in angled relationship so as to define a plane; b) three legs, each leg extending from said base portion and being integral therewith, each said leg having a proximal surface for the reception of a distally directed applier force, and each said leg being bendable at a bendable hinge region in response to application of said applier force from a first position in which each said leg is oriented such that it is not in angled relation to the plane defined by said base portion, to a second position wherein each said leg is oriented at an angle to said plane defined by said base portion, wherein each leg includes an end portion integral therewith and oriented at an angle to its respective leg.
Claim 10
Dependent Claim
152 words
A surgical fastener for closure of a Y-shaped incision, which comprises: a unitary body having a) a base portion which includes three rectilinear members connected to each other in angled relationship so as to define a plane; b) three legs, each leg extending from said base portion and being integral therewith, each said leg having a proximal surface for the reception of a distally directed applier force, and each said leg being bendable at a bendable hinge region in response to application of said applier force from a first position in which each said leg is oriented such that it is not in angled relation to the plane defined by said base portion, to a second position wherein each said leg is oriented at an angle to said plane defined by said base portion, wherein each leg includes an end portion integral therewith and oriented at an angle to its respective leg.
Claim 11
Dependent Claim
19 words
The surgical fastener of claim 8 wherein said rectilinear members of said base portion define a triangular shaped configuration.
Claim 12
Dependent Claim
