BIAS-CUT ARTIFICIAL BLOOD VESSEL

for the small caliber artery

Abstract

Encouraged at the preliminary data on the application of bias-cut artificial blood vessel to the small caliber arterial reconstruction, the implantation experiment on dog has been continuing to verify the original assumption of maintaining biological porosity close to the original porosity which resists scar contraction.
70% of patency rate was found both on the bias-cut grafts and on the control side of 4mm I. D. Microknit grafts by angiography and/or autopsy in a period of nearly 2 years.
It was found on a review of recovered specimens up to one year of implantation histologically that the inner capsule of bias-cut grafts showed better vascularity in basal layer than the inner capsule of control grafts did.
Good biological porosity found in the bias-cut grafts is quite unique and advantageous to the development of a small caliber arterial prosthesis.
