PROSTHESIS FOR BLOOD VESSEL

摘要

A prosthesis for a blood vessel which is manufactured from a stretched porous polytetrafluoroethylene tube having a fine fiber-like structure comprising fibers and knobs connected with one another by said fibers, characterized in that it has an average fiber length of 40 mu m or more and a porosity of 70 % or more, and a load required for compressing said tube by 10 % in the direction of the tube axis thereof at a stress rate of 100 %/min is 10 gf or more and a resistant force produced in the above-mentioned 10 % compression is 1.0 gf/mm<2> or more per unit area of the cross section of said tube.
