    摘要： A method and device to repair a stenosis in a blood vessel is provided. The medical device has a tubular member and a frame. The frame may be expanded or contracted while maintaining its generally cylindrical configuration. The medical device is retained in a contracted state inside an introducer sheath. The introducer sheath is guided through the stenosis such that a first end of the medical device is located distal the stenosis. The introducer sheath is retracted relative to the medical device, such that the first end of the stent expands to engage the blood vessel distal the stenosis. A mid-portion of the medical device engages the plaque of the stenosis trapping any emboli against the wall of the vessel. The second end expands to engage the blood vessel proximal to stenosis.

    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： A non-implantable valve assembly and a method for controlling flow rates in a medical device are provided. The valve assembly includes a valve member being dimensioned for reception at least partially within a lumen of the medical device. The valve member includes a flow regulator for controlling flow rates in a first direction having a first rate and a second direction having a second rate. The second rate is greater than the first rate.

    摘要： A one-way valve apparatus for use in draining fluid from a patient comprises a housing having an inlet end, an outlet end and a valve-receiving chamber therebetween. A valve is positioned in the chamber. The valve has an inlet end, an outlet end and a fluid pathway extending therebetween. The valve is made up of first and second generally flat elongated members joined along respective longitudinal edges. The valve inlet end is engaged with the housing inlet end to comprise an open end for receiving fluid to be drained. The valve outlet end is in a normally closed position. The valve is adapted to partially open to permit drainage of fluid received through the pathway, and to return to the normally closed position upon drainage of the fluid. The valve outlet end communicates with the housing outlet end such that the drained fluid passes from the valve outlet end through the housing outlet end. The valve may be formed from an elastomeric material, and may be provided with a lubricious filler and/or a lubricous coating.

    摘要： Endolumenal medical devices for implantation within a body vessel are provided. The medical devices may comprise a light-transmitting area having an adhesive-activating effective transmittance at a wavelength suitable for activating a light-activated adhesive. The light-activated adhesive is preferably positioned on the medical device and may be activated by illumination inside a body vessel with light of a suitable wavelength, including ultraviolet, visible or infrared radiation, to secure the medical device within a body vessel. The light may be provided by a light-emitting catheter within the body vessel, and the medical device may be configured as a radially-expandable valve comprising one or more valve leaflets.
