1. An intravascular prosthesis comprising:

  • a lining rolled upon itself in a plurality of turns around a longitudinal axis so that it is introducible into a vascular lumen surrounded by a vascular wall;

    an inflatable channel associated with said lining and being rolled upon itself around said longitudinal axis, said channel including a filling port for the introduction of fluid into said channel for the inflation thereof, said lining and said channel having the capability of unrolling when said channel is inflated so that the lining may engage the vascular wall to provide support therefor; and

    a porous filter connected to said lining and positioned so that, when the lining is unrolled, said filter extends substantially transversely across the interior of said unrolled lining to prevent blood from passing through the prosthesis.
