AbstractA braided self-expandable stent-graft-membrane made of elongated members forming a generally tubular body. A membrane layer and graft layer are disposed on a endoprosthesis such as a stent. The membrane layer is substantially impermeable to fluids. The outermost layer is biocompatible with the body tissue. The innermost layer is biocompatible with the fluid in the passage. An embodiment includes a graft layer disposed on the inside of a stent and a membrane layer disposed on the outside of the stent. The innermost layer is biocompatible with the fluid in the passage. The stent-graft-membrane is used at a treatment site in a body vessel or organ where it is desirous to exclude a first fluid located outside the endoprosthesis from reaching a second fluid located in the lumen. The membrane may be made of silicone or polycarbonate urethane. The graft may be braided, woven, spun or spray-cast PET, PCU, or PU fibers. The layers may include ePTFE or PTFE.
