Abstract
A prosthesis for a blood vessel, which is an expanded porous polytetrafluoroethylene tube having a fine fibrous structure with nodes connected to each other by fibrils. The average fibril length is at least 40 &mgr;m, and the tube has a porosity of at least 70%. The load required for compressing the tube by 10% in its axial direction at a strain rate of 100%/min is at least 10 gf. The resistant force per unit sectional area of the tube produced upon the 10% compression is at least 1.0 gf/mm .
