Abstract

The surface composition of a biomaterial can have an important influence on biologic responses. In this paper we report on a surface treatment using a gas discharge which deposits a thin fluorocarbon polymer coating onto tie surface of a synthetic vascular graft. The surface chemistry of the graft is significantly changed, while there is no measurable change in porosity, compliance or surface topography. Treatments with tetrafluoroethylene (TFE) gas yield dramatic improvements in both thrombo and emboli-resistance of the graft, based on in vitro measurements and ex vivo shunt tests in a baboon.
