Abstract
Abstract An improved nonmetallic surgical clip having two separate arms joined together at an apex is disclosed. The improvement comprises a weakened portion and a bend in at least one arm. The bend is at the weakened portion. The amount of the bend is such that at least a part of one arm is in an essentially parallel relationship with at least a part of the other arm.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
112 words
A nonmetallic surgical clip having two separate parts, the first part comprising two arms joined together at an apex, a pair of tracks contained on the opposite exterior surface of each arm, a weakened portion and a bend in at least one arm, said bend being at said weakened portion and the amount of said bend being such that at least a part of one arm is in an essentially parallel relationship with at least a part of the other arm, and the second part comprising a U-shaped member having two legs capable of being engaged between the respective tracks of said first part for approximating the cooperating surfaces of said arms.
Claim 2
Dependent Claim
112 words
A nonmetallic surgical clip having two separate parts, the first part comprising two arms joined together at an apex, a pair of tracks contained on the opposite exterior surface of each arm, a weakened portion and a bend in at least one arm, said bend being at said weakened portion and the amount of said bend being such that at least a part of one arm is in an essentially parallel relationship with at least a part of the other arm, and the second part comprising a U-shaped member having two legs capable of being engaged between the respective tracks of said first part for approximating the cooperating surfaces of said arms.
Claim 3
Dependent Claim
100 words
A nonmetallic synthetic bioabsorbable surgical clip having two separate parts, the first part comprising two symmetrical arms joined together at an apex, a protrusion adjacent said apex and opposite the proximal ends of said arms, a weakened portion and a bend in each arm, said bend being at said weakened portion and the amount of said bend being such that the distal ends of said arms are in an essentially parallel relationship, and the second part comprising a U-shaped member for approximating the cooperating surfaces of said arms, wherein the distal end of said U-shaped member is contacting said protrusion.
Claim 4
Dependent Claim
100 words
A nonmetallic synthetic bioabsorbable surgical clip having two separate parts, the first part comprising two symmetrical arms joined together at an apex, a protrusion adjacent said apex and opposite the proximal ends of said arms, a weakened portion and a bend in each arm, said bend being at said weakened portion and the amount of said bend being such that the distal ends of said arms are in an essentially parallel relationship, and the second part comprising a U-shaped member for approximating the cooperating surfaces of said arms, wherein the distal end of said U-shaped member is contacting said protrusion.
Claim 5
Dependent Claim
22 words
A clip of claim 1 or 2 wherein the nonmetallic material is a synthetic bioabsorbable polymer having a glycolic acid ester linkage.
Claim 6
Dependent Claim
30 words
A clip of claim 3 wherein said first part is a copolymer containing glycolic acid ester and trimethylene carbonate linkages, and said second part is a homopolymer of glycolic acid.
Claim 7
Dependent Claim
22 words
A clip of claim 1 wherein the apex of said first part is essentially contiguous with a portion of said second part.
