[New textile vascular prostheses made of polymer composition materials].
Functional properties of blood vessel prostheses to large degree depend on the longitudinal elasticity of their walls. Theoretical foundations for designing the physico-chemical properties of prostheses walls were worked out, and special methods and measuring apparatuses. New types of vascular textile prostheses make it possible to model biological tissues. The prostheses walls are a composition of polymers of several types of threads differing to large degree in their elasticity. Comparative theoretical and experimental studies on natural blood vessels, blood vessel prostheses (of traditional threads) and new textile prostheses showed that the last mentioned, as far as their elasticity in concerned, are most close to the requirements and that they have good functional properties.
