Abstract
The present invention relates to an implantable prosthesis having a membrane and a fluid channel that are inserted into a body lumen to maintain fluid flow and support the lumen wall. A preferred embodiment of the invention includes a mesh membrane or filter attached to a covered stent. The membrane can be mounted on a frame formed with a shape memory material that can be delivered through a catheter into a body lumen. The membrane and the frame can expand from a delivery state into an expanded state.
