Abstract

See full text

A composite vascular graft is provided, which incorporates bioactive agents that can be controllably delivered to the implantation site to deliver therapeutic materials and/or to reduce infection of the implant. The vascular graft of the present invention includes a luminal layer of ePTFE; and a biodegradable polymer layer including a bioactive agent, such as an antimicrobial agent. The biodegradable polymer layer is posited on the external surface of the luminal ePTFE layer. The graft also includes a fabric layer, which is posited on the external surface of the biodegradable layer. The graft is particularly useful as an arterial-venous graft for hemodialysis procedures.
