Patent ID: 8597366

Claim:
A coated stent, the coated stent having an outer surface and an inner surface, the coated stent comprising: a tubular inner sleeve, the inner sleeve having a proximal end and a distal end, the inner sleeve being made of a polymeric material; a stent covering at least a portion of the inner sleeve, the stent having a proximal end and a distal end, the proximal end of the stent being flared; a coating on the stent to bond the stent to the inner sleeve, the coating being a polymeric material that is the same as the polymeric material of the inner sleeve; a plurality of anchors engaged to the stent, the anchors extending radially outward from the stent; a valve positioned within the inner sleeve at a position that is covered by the stent having two or three valve flaps that close a lumen defined by the inner sleeve; wherein the inner sleeve has a length longer than the stent and the proximal end of the inner sleeve is distal to the proximal end of the stent; wherein the stent forms the outer and inner surfaces of a proximal end portion of the coated stent, the coating forms the outer surface of a middle portion of the coated stent, and the inner sleeve forms the outer surface of a distal portion of the coated stent and the inner surface of the middle and distal portions of the coated stent; and wherein the portion of the inner sleeve forming the distal portion of the coated stent has a flexibility that allows the inner sleeve to collapse and form a one-way valve.
