A new method of preclotting fabric prostheses. A preliminary report

A new method of preclotting arterial fabric prostheses is described. The preclotting process depends on infusion of blood into a polyethylene bag containing the prosthesis. Massage of the bag aids permeation of the graft, and a second infusion of blood over a 1 minute period seals the fraft completely. Rapid preclotting and asepsis are the unique features of this method.
