Abstract

He impregnated a highly porous, knitted polyester (Dacron) graft with a biodegradable nonproteinaceous material, algin. This new vascular graft is blood tight but still retains high porosity in the body. It does not need to be preclotted with blood before implantation and has good tissue ingrowth and biological healing properties due to the high porosity. The algin impregnated graft was investigated by "in vitro" examinations in this study. It was characterized by ESCA analysis, SEM observation, and measurements of water permeability, algin coating weight, mechanical properties and whole blood clotting time. The water permeability of the graft was reduced more than 99% by the algin impregnation treatment without changing any mechanical properties. "In vivo" examinations of the algin impregnated vascular graft are on progress.
