Abstract
A prosthetic vascular graft with walls less than O.8B millimeters in thickness and formed of highly expanded polytetrafluoroethylene with a microscopic superstructure of nodes and interconnecting fibrils, which nodes are substantially uniformly separated by an average distance greater than a typical red cell. The superstructure of the graft controls transmural cellular ingrowth and assures the establishment and maintenance of a thin,viable neointima.
