The conventional synthetic grafts usually show acar contraction by about 10% on the average. The bias cutting permits the graft to be stretched by about 20%, and restore the initial porosity even if scar contraction occurs. Even two years after the implantation in the thoracic aortae of dogs, the grafts were still stretched by 10% on the average; the inner capsule was not more than 200μ in thickness, the space between fiber bundles was as wide as 100μ. It is, hence, capable of keeping the inner capsule thin and maintaining the biological porosity, and is of significance in healing after implantation of grafts.
