摘要: A medical device comprises a support structure and one or more graft members comprising a valve portion and a constraining portion. The support structure has a first, unexpanded configuration and a second, expanded configuration. The constraining portion is adapted to substantially prevent the support structure from achieving the second, expanded configuration. The valve portion is adapted to permit fluid flow through a body vessel in a first direction and substantially prevent fluid flow through the vessel in a second, opposite direction.

摘要: An valve prosthesis, such as an artificial venous valve, having a support frame and leaf structure comprising one or more leaflets in which the outer edge of each leaflet engages the inner circumference of the bodily passageway along a serpentine path urged against the passageway by an expandable frame, while the inner edges move in response to fluid to restrict retrograde flow. Optionally, one or more elements can extend from the support frame/leaf structure to provide centering support and/or protection from the leaflet adhering to the vessel wall. In one embodiment, the centering support structure comprises a second or third expandable frames attached to and extending from the proximal and/or distal ends of main valve structure and support frame. In another embodiment, one or more support elements extend outward from the valve support frame to engage the vessel wall to provide greater longitudinal stability.

摘要: A prosthetic valve includes a support frame, a leaflet attached to the support frame, and a bioactive agent associated with the leaflet. A first free edge of the leaflet permits fluid flow through a body vessel in a first direction and substantially prevents fluid flow through the body vessel in a second, opposite direction. A second free edge of the leaflet at least partially defines an opening for permitting a controlled amount of fluid flow through the body vessel.

摘要: Methods of implanting a prosthetic valve in a body vessel are provided. A first expandable frame member is delivered to and deployed at a point of treatment in a body vessel. A second expandable frame member is delivered to the point of treatment. The second expandable frame member has an attached graft member that forms a valve adapted to permit fluid flow through the body vessel in a first direction and to substantially prevent fluid flow through the body vessel in a second, opposite direction. After deployment of the first expandable frame member, the second expandable frame member is deployed at the point of treatment such that the second frame member is positioned radially inward of the first frame member within said body vessel to form a prosthetic valve.

摘要: Prosthetic valves for implantation in a body vessel are provided. Prosthetic valves according to the invention comprise first and second frame members and a graft member at least partially disposed between the first and second frame members. The graft member forms a valve that permits fluid flow through the body vessel in a first direction and substantially prevents fluid flow through the body vessel in a second, opposite direction.

摘要: Prosthetic valve devices for implantation in body vessels are provided. The prosthetic valve device includes at least one flexible member that permits fluid flow in a first direction and substantially prevents fluid flow in a second. The valve device also includes an inflatable chamber at least partially attached to the flexible member. The inflatable chamber is adapted to receive inflating media and is adapted to contact the body vessel. A delivery system is also provided that includes a valve device and a delivery apparatus. The delivery apparatus includes a member adapted for filling the chamber of the valve device with inflating media. A related method of making the valve device is also provided.
