摘要： Medical devices for implantation in a body vessel, and methods of using and making the same, are provided. Medical devices preferably comprise a remodelable material attached to a frame with a tension that can change upon implantation of the medical device within the lumen of a body vessel. Controlled fracture or bioabsorption of frame material can, in some embodiments, decrease the tension on the remodelable material after implantation. The remodelable material can form one or more valve leaflets adapted to regulate fluid flow in a body vessel, such as a vein.

摘要： An occlusion device has a covering attached to a support frame that includes a disc-shaped member and a crossbar that extends across a central opening defined by the disc-shaped member. The occlusion device has a first, or deployed, configuration in which the crossbar defines a curve that extends from the disc-shaped member, and a second, or resting, configuration in which the disc-shaped member and the crossbar lie substantially in a single plane. Each of the disc-shaped member and the crossbar include a core wire that extends through a lumen of a coil multiple times.

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.

摘要： Delivery systems, methods of fabricating delivery systems, and methods of implanting intraluminal medical devices at a point of treatment within a body vessel are provided. Delivery systems include an elongate tubular member that has first and second wall portions with different acoustic impedences. An intraluminal medical device is disposed on a mounting region of a dilator and within the elongate tubular member. One of the wall portions of the elongate tubular member is positioned substantially adjacent a functional mechanism of the intraluminal medical device. This positioning facilitates placement of the intraluminal medical device within a body vessel in a particular orientation by observing the differential reflection of ultrasonic waves caused by the different acoustic impedences of the first and second wall portions of the elongate tubular member. Rotatation of the delivery system following and/or during such an observation can be employed to achieve a desired orientation of the intraluminal medical device within the body vessel.

摘要： A medical device is adapted for at least partial implantation into a body and includes first and second sections along the length of the device. A first therapeutic agent is associated with the first section and a second therapeutic agent is associated with the second section. The first therapeutic agent can be one or more antiproliferative, such as paclitaxel, a paclitaxel derivative, or a paclitaxel pro-drug, anti-coagulant, antithrombotic, thrombolytic, fibrinolytic, or combination thereof. The second therapeutic agent can be one or more antimicrobials, such as one or more antibiotics. Each of the first and second therapeutic agents can either be posited on one or more surfaces of the respective section, or impregnated within the section. The device can include a separator to space the first and second sections. A method of making a medical device and a method of establishing access to a vessel within a body are also provided.

摘要： The present invention provides, in certain aspects, devices and methods for protecting the body from downstream embolization. In one embodiment, a distal protection device comprises a shaft and a jacket with the shaft being received within the jacket. The device also includes a filter, which is supported by a wire cone that has one end attached to the jacket and an opposite end attached to the shaft. The shaft is rotatable relative to the jacket to reduce the size of the cone for capturing embolic debris within the wire cone. The invention also provides such devices in combination with instruments (e.g., balloon stent catheters) for treating stenosis and other similar conditions.
