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