    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 for implanting a prosthetic valve in a body vessel having a fluid flow therethrough are provided. One method includes identifying a position of an existing valve and determining a factor affecting fluid flow in at least one of a first direction and a second direction at the existing valve. The method includes selecting the implantation position for a prosthetic valve at a distance away from the existing valve position in consideration of the factor. The method further includes providing the prosthetic valve for delivery to the implantation position, delivering and implanting the prosthetic valve at the position. The prosthetic valve includes at least one flexible member movable between a first position that permits fluid flow in the first direction and the second position that substantially prevents fluid flow in a second direction.

    摘要： Described are devices, methods and systems useful for achieving occlusion of vascular vessels. Percutaneous procedures can be used to occlude and obliterate the greater saphenous vein, for example in the treatment of varicose vein condition caused by venous reflux. Certain embodiments encompass the percutaneous delivery of an occlusion device inverted within a cannula, its deployment and filling, so as to occlude or obliterate a portion of a vascular vessel.

    摘要： Described are methods and systems for modifying vascular valves in order to reduce retrograde blood flow through the valves. Preferred methods include connecting vascular valve leaflets with at least one remodelable material, such that the valve leaflets become fused by the ingrowth of the patient's native tissue. Preferred remodelable materials include collagenous extracellular matrix material, such as small intestine submucosa.

    摘要： A venous valve prosthesis having a substantially non-expandable, valve portion comprising a valve-closing mechanism, such as a pair of opposing leaflets; and an anchoring portion, such as one or more self-expanding frames or stents that are expandable to anchor the prosthesis at the implantation site. In one embodiment, the rigid valve portion includes a deposition of material such as pyrolitic carbon to reduce the thrombogenecity of the blood-contacting surfaces. The anchoring portions preferably include a covering, such as a tubular construct of synthetic or collagen-derived material (such as a bioremodelable ECM material), which attaches about the support structure such that blood flow is directed through the valve mechanism as it transitions from the larger diameter anchoring portion to the intermediate, smaller-diameter portion of the prosthesis. In another embodiment, the valve support housing and valve-closing elements are delivered in a collapsed, folded, and/or dissembled state sized for delivery, then manipulated in situ to the second expanded configured following deployment.

    摘要： Implantable medical devices adapted to modify fluid flow within a body vessel are provided herein. The medical devices may include a fluid flow restricting channel configured to reduce longitudinal fluid flow in a retrograde direction or in an antegrade direction. Preferably, the medical devices are flow-modifying devices that reduce fluid flow through the medical device to a greater extent in a retrograde direction than in an antegrade direction. Methods of treatment comprising the step of implanting a flow-modifying medical device within a body vessel are also provided. Flow-modifying devices are useful, for example, in treating venous valve related conditions.
