    摘要: Medical devices for implantation in a body vessel are provided. A medical device according to the invention 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: 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 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.
