Vascular prostheses and process for producing the same

摘要: A process for producing tubular prostheses use in vascular reconstructive surgery is described. The invention comprises chemically and structurally modifying the veins arteries of human umbilical cord to obtain a grafting material which superior existing blood vessel substitutes. involves steps (a) removing internal from its outer tissue; (b) separating these vessels one another; (c) treating with cleansing tanning agents eliminate antigenicity; (d) shaping by inserting mandrel; (e) applying mesh support shaped tanned prosthesis. repairing, replacing augmenting animal vein or artery using prosthesis produced also
