    摘要： Medical devices for navigation through anatomy, including guidewires, which may have a core wire, a slotted tubular member, or both. Embodiments may have coils, including non-circular cross-section edge-wound marker coils, extended coil tips, and soldered or glued mesial joint coils. Core wires may have a step, ridge, or taper at the joints to the tubular member, and may be flattened at the distal tip. Radiopaque material may be located inside the tubular member, and the distal tip may be heat treated to make it shapeable. Additional tubular members or coils may be used concentrically or in line and may enhance flexibility, provide radiopacity, reduce friction, or reduce material or manufacturing cost. Tubular members may be chamfered or tapered continuously or incrementally. Slots may be arranged in groups, such as groups of tree, and may be equal in depth or unequal in depth to provide a steerable or compressible tip.

    摘要： A medical device or intravascular device, and methods of use. The devices may be tubular and may have a flexible polymer tip. The body may be nitinol and may have cuts part way through along its length to facilitate bending. The device may have a liner which may extend through the tip or form the tip. The device may have markers readily visible on an X-ray viewer during insertion. The tip may have an anti-collapsing structure and may be shaped before use to perform a medical procedure such as treating an aneurysm. The device may have a strong fiber through it for complete removal. The method may include selecting the device, bending the tip, setting the shape, and inserting the device into the patient's anatomy. The shape of the tip may be set by heating with steam and then removing a mandrel.

    摘要： A method for increasing the rate of thrombus formation and/or proliferative cell growth of a selected region (21) of cellular tissue (22) including the step of endovascularly irradiating the selected region (21) with radiation, having a dose range of endovascular radiation of about 1 Gy to about 600 Gy at a low dose rate of about 1 cGy/hr to about 320 cGy/hr, to increase thrombus formation and/or cell proliferation of the affected selected region (21). Preferably, the delivery means includes a deformable endovascular prosthesis (25) adapted for secured positioning adjacent to the selected region (21) of cellular tissue (22), and a radioactive source. This source cooperates with the deformable endovascular device (25) in a manner endovascularly irradiating the selected region with radiation, having the above-indicated dose range and low dose rate of endovascular radiation to increase thrombus formation and/or cell proliferation of the affected selected region (21).

    摘要： The drug loaded stent includes an expandable stent structural member, and a planar sheet of polymeric material attached to the outside of the expandable stent structural member. The polymeric material is preferably bioabsorbable, and loaded or coated with a therapeutic agent or drug to reduce or prevent restenosis in the vessel being treated. The polymer material can be attached to the metal stent at one or more points, and wrapped in a coil around the stent in an unexpanded state, to uncoil and expand in diameter to substantially match the expanded diameter of the metal stent; or can be wrapped tightly around the stent structural member and attached to itself, to stretch radially when the stent structural member is expanded. In another currently preferred embodiment, a combination of a stent structural member and a polymeric film wrapping can be provided with a coating of lubricious material. The lubricious material can be polyethylene oxide, polyethylene glycol, polyethylene acetate, polyvinyl pyrrolidone, polyvinyl alcohol, polyacrylamide, hydrophilic soft segment urethanes, some natural gums, polyanhydrides or other similar hydrophilic polymers, and combinations thereof. The layer of lubricious material protects the stent from the guide or the body lumen in which the stent is inserted by providing a low friction surface over the stent.
