Patent ID: 7628804

Claim:
A medical device for implantation in a body vessel, comprising: a tubular main body having an outer diameter, defining a passageway and comprising an outer surface having a portion that is impervious to fluid flow; a valve disposed in the passageway and adapted to permit fluid flow through the passageway in a first direction and substantially prevent fluid flow through the passageway in a second, opposite direction, the valve having a proximal end, a distal end, and an axial length; and a compressible vessel engaging member disposed on the outer surface of the main body and adapted to substantially prevent fluid flow through the body vessel in the second, opposite direction, the vessel engaging member having first and second opposing surfaces, an inner edge, an aperture defined by the inner edge and extending coaxially with the main body from the first surface to the second surface, an outer edge, and a radial thickness extending from the inner edge to the outer edge; wherein the main body is disposed through the aperture and extends axially beyond the first and second surfaces of the vessel engaging member and axially beyond the proximal and distal ends of the valve, and the portion of the outer surface of the main body that is impervious to fluid flow extends at least along the axial length of the valve; and wherein the vessel engaging member has an expanded configuration in which the radial thickness of the vessel engaging member is larger than the outer diameter of the main body; wherein the vessel engaging member further comprises a bioremodellable material; and wherein the main body further comprises a self-expanding support frame.
