Claims Analysis

Total Claims: 27
Claim 1
Independent Claim 82 words
A coherent surgical-staple stack comprising: a plurality of individual, deformable surgical staples, each of said staples including a pair of legs joined together at one end by a crown, said staples arranged one next to the other in a contiguous parallel array with any two adjacent staples having their legs and crowns touching; and a film made from a biologically compatible non-toxic material, said film being disposed between adjacent staples in said array for bonding said adjacent staples one to the other.
Claim 2
Dependent Claim 82 words
A coherent surgical-staple stack comprising: a plurality of individual, deformable surgical staples, each of said staples including a pair of legs joined together at one end by a crown, said staples arranged one next to the other in a contiguous parallel array with any two adjacent staples having their legs and crowns touching; and a film made from a biologically compatible non-toxic material, said film being disposed between adjacent staples in said array for bonding said adjacent staples one to the other.
Claim 3
Dependent Claim 16 words
The stack of claim 1, wherein said material is biologically degradable and absorbable in the body.
Claim 4
Dependent Claim 12 words
The stack of claim 2, wherein said material is a synthetic polymer.
Claim 5
Dependent Claim 11 words
The stack of claim 3, wherein said polymer comprises polyglycolic acid.
Claim 6
Dependent Claim 11 words
The stack of claim 3, wherein said polymer comprises polylactic acid.
Claim 7
Dependent Claim 16 words
The stack of claim 3, wherein said material comprises a copolymer of polylactic and polyglycolic acids.
Claim 8
Dependent Claim 21 words
The stack of claim 6, wherein said biologically compatible material comprises a copolymer of 90% polylactic acid with 10% polyglycolic acid.
Claim 9
Dependent Claim 13 words
The stack of claim 7, wherein the polylactic acid is primarily the L+stereoisomer.
Claim 10
Dependent Claim 10 words
The stack of claim 1, wherein said material is biodegradable.
Claim 11
Dependent Claim 72 words
A coherent surgical-staple stack comprising: a plurality of individual deformable surgical staples, each of said staples including a pair of legs joined together at one end by a crown, said staples arranged one next to the other in a contiguous parallel array with any two adjacent staples having their similar legs and crowns touching, and a biodegradable, absorbable plastic disposed about adjacent staples for securing said adjacent staples one to the other.
Claim 12
Dependent Claim 72 words
A coherent surgical-staple stack comprising: a plurality of individual deformable surgical staples, each of said staples including a pair of legs joined together at one end by a crown, said staples arranged one next to the other in a contiguous parallel array with any two adjacent staples having their similar legs and crowns touching, and a biodegradable, absorbable plastic disposed about adjacent staples for securing said adjacent staples one to the other.
Claim 13
Dependent Claim 50 words
For use in a surgical stapling instrument that deforms individual surgical staples in the act of stapling disunited tissue, a coherent stack of staples comprising: a plurality of individual deformable surgical staples arranged in a parallel contiguous relationship, and a biologically compatible material securing said staples one to the other.
Claim 14
Dependent Claim 50 words
For use in a surgical stapling instrument that deforms individual surgical staples in the act of stapling disunited tissue, a coherent stack of staples comprising: a plurality of individual deformable surgical staples arranged in a parallel contiguous relationship, and a biologically compatible material securing said staples one to the other.
Claim 15
Dependent Claim 11 words
The stack of claim 11, wherein said material is biologically degradable.
Claim 16
Dependent Claim 13 words
The stack of claim 11, wherein said material is absorbable in the body.
Claim 17
Dependent Claim 13 words
The stack of claim 11, wherein said material is a synthetic absorbable polymer.
Claim 18
Dependent Claim 13 words
The stack of claim 14, wherein said polymer is made from polyglycolic acid.
Claim 19
Dependent Claim 13 words
The stack of claim 14, wherein said polymer is made from polylactic acid.
Claim 20
Dependent Claim 16 words
The stack of claim 14, wherein said polymer comprises a copolymer of polylactic and polyglycolic acid.
Claim 21
Dependent Claim 21 words
The stack of claim 17, wherein said biologically compatible material comprises a copolymer of 90% L+lactic acid with 10% glycolic acid.
Claim 22
Dependent Claim 13 words
The stack of claim 1, wherein said surgical staples are made of metal.
Claim 23
Dependent Claim 13 words
The stack of claim 11, wherein said surgical staples are made of metal.
