Abstract
Arteries and veins of umbilical cords are hardened and shaped by processes described. Prostheses in the form of tubes, patches and conduits are prepared from the shaped vessels. The prostheses are used as reinforcements and replacements for vessels, ducts, intestines and urinary bladders. The processes result in products which have vanishingly low antigenicity and thrombogenicity, are resistant to infection and which may be stored indefinitely for use when needed by a surgeon.
