Vettivetpillai Ketharanathan: Vascular prostheses. Finnegan Henderson Farabow Garrett & Dunner, March 16, 1982: US04319363 (87 worldwide citation)

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 w ...
