ABSTRACT:
A vascular graft comprised of a tubular polytetrafluoroethylene (ePTFE) sheet is provided. The ePTFE sheet has a substantially uniform coating of bioresorbable gel material, for example gelatin, on a surface thereof. The coating minimises bleeding through suture holes in the ePTFE sheet and provides an increase in longitudinal extensibility.
