ABSTRACT:
Vascular prosthesis suitable for use as a surgical graft is produced by implanting a rod or tube in a living host animal such as a sheep and allowing collagenous tissue to grow on the implant to form a coherent tubular wall of collagenous tissue. The implant is subsequently removed and the tubular wall of collagenous tissue is stripped from the rod or tube and tanned in glutaraldehyde to serve as a vascular prosthesis.
