Abstract
A method for preparing human and other animal unbilical cords for use as a vascular replacement and/or arterial venous fistula which permits the umbilical cord which is to be grafted to be preformed into a desired predetermined configuration. The method includes the steps of initially flushing the cord in an aqueous solution, and then mounting the flushed cord upon a mandrel having the desired configuration. The mounted cord is immersed in ethyl alcohol until substantially dehydrated and preformed, and is thereafter immersed for fixation in an aldehyde selected from the class consisting of dialdehyde starch and gluteraldehyde, with the aldehyde immersion fixing the tissue into a shape conforming to the mandrel upon which it is mounted.
