  • Abstract
  • Look Inside

Healing characteristics in a highly porous fabric prosthesis are better than in a porously low one. How-ever, bleeding from the highly porous graft wall after implantation has been a very big problem for surgeons, preventing them from using this prosthesis.

When a small-caliber graft is preclotted and implant-ed, the condition of the inner surface, such as smooth-ness, enhances patency and antithrombogenicity. We developed a method for preclotting a highly porous small-caliber fabric prosthesis using Teflon Mandril.

Before preclotting, a fabric vascular prosthesis was held end-to-end and stretched to make the crimp shal-low.
