Abstract
This invention is directed to graft materials for implanting, transplanting, replacing, or repairing a part of a patient and to methods of making the graft materials. The present invention is also directed to stent grafts and endoluminal prostheses formed of the graft materials. More specifically, the present invention is a graft material which includes porous polymeric sheet, extracellular matrix material (ECM) disposed on at least a portion of the porous polymeric sheet and at least one polymer layer disposed on at least a portion of the ECM. The ECM may be in a gel form. The polymeric sheet and the polymer layer may be made from foam material and may comprise a polyurethane urea and a surface modifying agent such as siloxane.
