Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
70 words
A vascular graft comprising individual air jet textured yarns each of which includes a core of at least one essentially straight filament and an outer layer of small, compact loops which are firmly entangled with said at least one core filament, said individual air jet textured yarns being interengaged into a fabric structure which is constructed and arranged in a tubular configuration and has a lumen for conveying blood therethrough.
Claim 2
Dependent Claim
70 words
A vascular graft comprising individual air jet textured yarns each of which includes a core of at least one essentially straight filament and an outer layer of small, compact loops which are firmly entangled with said at least one core filament, said individual air jet textured yarns being interengaged into a fabric structure which is constructed and arranged in a tubular configuration and has a lumen for conveying blood therethrough.
Claim 3
Dependent Claim
22 words
The vascular graft recited in claim 1 wherein at least a portion of said air jet textured yarns include micro-denier filament yarns.
Claim 4
Dependent Claim
26 words
The vascular graft recited in claim 1 further including yarns which have not been air jet textured which are interengaged with said air jet textured yarns.
Claim 5
Dependent Claim
36 words
The vascular graft recited in claim 3 wherein said air jet textured yarns include micro-denier filament yarns and said yarns which have not been air jet textured have a denier to filament ratio greater than one.
Claim 6
Dependent Claim
82 words
A woven vascular graft comprising warp yarns, and individual filling yarns which have been air jet textured, each of said filling yarns including a core of at least one essentially straight filament and an outer layer of small, compact loops which are firmly entangled with said least one core filament, said warp and air jet textured filling yarns being woven together into a fabric structure which is constructed and arranged in a tubular configuration and has a lumen for conveying blood therethrough.
Claim 7
Dependent Claim
82 words
A woven vascular graft comprising warp yarns, and individual filling yarns which have been air jet textured, each of said filling yarns including a core of at least one essentially straight filament and an outer layer of small, compact loops which are firmly entangled with said least one core filament, said warp and air jet textured filling yarns being woven together into a fabric structure which is constructed and arranged in a tubular configuration and has a lumen for conveying blood therethrough.
Claim 8
Dependent Claim
18 words
The woven vascular graft recited in claim 5 wherein said air jet textured yarns include micro-denier filament yarns.
Claim 9
Dependent Claim
55 words
A vascular graft containing individual air jet textured micro-denier filament yarns each of which includes a core of at least one essentially straight filament and an outer layer of small, compact loops which are firmly entangled with said at least one core filament, said micro-denier filament yarns being interengaged into a seamless tubular fabric structure.
Claim 10
Dependent Claim
55 words
A vascular graft containing individual air jet textured micro-denier filament yarns each of which includes a core of at least one essentially straight filament and an outer layer of small, compact loops which are firmly entangled with said at least one core filament, said micro-denier filament yarns being interengaged into a seamless tubular fabric structure.
