Abstract
Abstract A thinly woven textile prosthetic implant such as a vascular graft may be implanted by catheter implantation. The implant includes an elongate tubular body formed of a woven fabric having a fabric thickness no greater than about 0.16 mm. The tubular body includes a series of longitudinally spaced wave-like generally uniform crimps along the length thereof. The crimps are disposed at a fine pitch along the length of the tubular body. The amplitude of the crimps is relatively small thus reducing the formation of thrombus and plaque on the inside of the implant.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
64 words
A woven textile prosthetic implant comprising: an elongate tubular body formed of a fabric wall having a fabric wall thickness no greater than about 0.16 mm, said tubular body having longitudinally spaced wave-like, generally uniform crimps along the length thereof, said crimps extending on both sides of said tubular body and having a crimp frequency of no less than about 6 crimps per centimeter.
Claim 2
Dependent Claim
64 words
A woven textile prosthetic implant comprising: an elongate tubular body formed of a fabric wall having a fabric wall thickness no greater than about 0.16 mm, said tubular body having longitudinally spaced wave-like, generally uniform crimps along the length thereof, said crimps extending on both sides of said tubular body and having a crimp frequency of no less than about 6 crimps per centimeter.
Claim 3
Dependent Claim
19 words
A woven textile prosthetic implant of claim 1 wherein said tubular body includes an x-ray detectable, radiopaque yarn therein.
Claim 4
Dependent Claim
21 words
A woven textile prosthetic implant of claim 2 wherein said radiopaque yarn extends longitudinally along the length of the tubular body.
Claim 5
Dependent Claim
23 words
A woven textile prosthetic implant of claim 1 wherein said wave-like crimps have a peak-to-peak amplitude of no greater than about 0.5 mm.
Claim 6
Dependent Claim
30 words
A woven textile prosthetic implant of claim 1 wherein said body has a fabric thickness of about 0.12 mm and a maximum crimp frequency of about 42 crimps per cm.
Claim 7
Dependent Claim
67 words
A woven textile graft comprising: an elongate tubular graft body having a wall, said wall having a thickness of no greater than about 0.16 mm and defining a pattern of wave-like crimps extending along both sides of said tubular body, the number of crimps, C, per centimeter of body length being defined by an equation: C= 2(t→10)!.sup.-1 ; wherein t equals the body wall thickness in mm.
Claim 8
Dependent Claim
67 words
A woven textile graft comprising: an elongate tubular graft body having a wall, said wall having a thickness of no greater than about 0.16 mm and defining a pattern of wave-like crimps extending along both sides of said tubular body, the number of crimps, C, per centimeter of body length being defined by an equation: C= 2(t→10)!.sup.-1 ; wherein t equals the body wall thickness in mm.
