Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 51 words
A surgical fastener comprising a blend of a copolymer containing from about 65 to about 90 mol per cent lactide and from about 10 to about 35 mol per cent glycolide, and poly(p-dioxanone), said blend containing from about 25 to about 50 weight per cent poly(p-dioxanone), the remainder comprising said copolymer.
Claim 2
Dependent Claim 51 words
A surgical fastener comprising a blend of a copolymer containing from about 65 to about 90 mol per cent lactide and from about 10 to about 35 mol per cent glycolide, and poly(p-dioxanone), said blend containing from about 25 to about 50 weight per cent poly(p-dioxanone), the remainder comprising said copolymer.
Claim 3
Dependent Claim 128 words
The surgical fastener of Claim 1 in the form of a staple comprising: (a) a fastener member including a base member and at least one leg member terminating in a pointed free end, said leg member extending substantially perpendicularly from said base member; and (b) a receiving member including at least one aperture arranged and constructed to receive and retain the free end of said leg member, wherein said fastener member comprises a blend of a copolymer containing from about 65 to about 90 mole per cent lactide and from about 10 to about 35 mole per cent glycolide, and poly(p-dioxanone), said blend containing from about 25 to about 50 weight per cent poly(p-dioxanone), the remainder comprising said copolymer, and wherein said receiving member is an absorbable polymer.
Claim 4
Dependent Claim 12 words
The surgical fastener of Claim 2 wherein said absorbable polymer is poly(p-dioxanone).
Claim 5
Dependent Claim 44 words
The surgical fastener of any one of claims 1 to 3 wherein, said copolymer contains about 85 mole per cent polymerized lactide, the remainder being polymerized glycolide, and wherein said blend contains about 70 weight per cent of said copolymer, the remainder comprising poly(p-dioxanone).
Claim 6
Dependent Claim 28 words
The surgical fastener of claim 1 or claim 4 when dependent on claim 1 in the form of a ligating clip, an anastomotic coupler, or a fascia closure.
