Abstract
Abstract An artificial vessel made of an elastomer comprising a skin layer at least in the inner surface area of the vessel wall and a spongy structure in the inside region of the vessel wall, and having a compliance of 0.1 to 0.8. The artificial vessel has a compliance approximate to that of a vital vessel and is particularly useful as an artificial vessel for artery with small diameter.

Claim 3
Dependent Claim
31 words
The artificial vessel of Claim 1, wherein there are pores of 1 to 50 µm in diameter in the skin layer and in the partition walls which form the spongy structure.
Claim 4
Dependent Claim
33 words
A process for preparing an artificial vessel, which comprises exdruding an elastomer solution together with an inside coagulating liquid from an annular nozzle and immersing the tubular extrudate into an outside coaqulating liquid.
