Abstract
Abstract An artificial vessel having a compliance and a stress-strain curve approximate to those of a vital vessel, which comprises a porous part of an elastomer and a tubular part of fibers, said tubular part being in contact with and/or bonded to at least one part of the porous part. The artificial vessel can be prevented from breakage and damage at a high blood pressure and has an excellent durability.

Claim 2
Dependent Claim
49 words
An artificial vessel having a compliance and a stress-strain curve approximate to those of a vital vessel, which comprises a porous part of an elastomer and a tubular part of fibers, said tubular part being in contact with and/or bonded to at least one part of the porous part.
Claim 3
Dependent Claim
13 words
The artificial vessel of Claim 1, wherein the compliance is 0.1 to 0.8.
Claim 4
Dependent Claim
49 words
The artificial vessel of Claim 1, wherein the strain is 0.1 to 0.8 at a stress of 0.01 kg/mm 2 , the strain is 0.4 to 1.2 at a stress of 0.05 kg/mm 2 and the strain is 0.5 to 1.5 at a stress of 0.12 kg/mm 2 .
Claim 5
Dependent Claim
83 words
A process for preparing an artificial vessel having a compliance and a stress-strain curve approximate to those of a vital vessel, which comprises a step for coating a mandrel with an elastomer solution containing a pore-forming agent and/or an elastomer solution having a cloud point, and a step for immersing the coated mandrel into a coagulating liquid, said steps being repeated once or more times, wherein a tubular element of fibers is arranged on the mandrel in at least one of the steps.
Claim 6
Dependent Claim
83 words
A process for preparing an artificial vessel having a compliance and a stress-strain curve approximate to those of a vital vessel, which comprises a step for coating a mandrel with an elastomer solution containing a pore-forming agent and/or an elastomer solution having a cloud point, and a step for immersing the coated mandrel into a coagulating liquid, said steps being repeated once or more times, wherein a tubular element of fibers is arranged on the mandrel in at least one of the steps.
