摘要： Medical devices that are visible by magnetic resonance imaging (MRI), and optionally, other imaging techniques, are described. In some embodiments, a medical device adapted for insertion into the body includes an elongated shaft (22) and an electrically conductive path (26) extending spirally about a portion of the shaft. The conductive path is capable of being connected to a current source. The medical device can further include one or more contrast agents (such as MRI contrast agents, radiopaque materials, and/or ultrasound visible materials), which can be arranged in a predetermined manner.

摘要： A process for treating nitinol so that desired mechanical properties are achieved. In one embodiment, the process comprises the steps of exposing the nitinol to a primary annealing temperature within the range of approximately 475 °C to 525 °C for a first time period, and thereafter exposing the nitinol to a secondary annealing temperature within the range of approximately 550 °C to 800 °C for a second time period. The invention also includes nitinol articles made by the process of the invention.

摘要： A thrombosis filter which can be securely affixed at a selected location in the vascular system of a patient and removed when no longer required. A first embodiment of the thrombosis filter includes a plurality of struts having a first grouping and a second grouping. The first grouping of struts and the second grouping of struts radiate in opposite directions. The free ends of the struts include anchoring elements which anchor into the walls of a blood vessel. At least one grouping of struts is comprised of a shape memory material. When these struts are at body temperature, their free ends engage the wall of the blood vessel. When the temperature of the shape memory alloy struts is selectively varied from body temperature, the struts retract into the body portion of the thrombosis filter.

摘要： Composite medical devices, such as catheters, or the like. In at least some embodiments, composite medical devices, and/or shafts for use therein, that can include a more flexible inner portion and a less flexible outer portion. In some embodiments, the composite elongate shaft can be constructed by forming a metallic outer portion including a first metallic material about a metallic inner portion including a second metallic material different from the first material. The second metallic material can be more flexible than the first metallic material. A segment of the metallic outer portion can then be removed from the composite shaft to expose a segment of the metallic inner portion. As portions of the outer portion are removed, and/or portions of the inner portion are exposed, certain characteristics along the length of the shaft can be achieved. For example, portions of the shaft can be rendered more flexible by the removal of the outer portion to expose the inner portion. Additionally, portions of the shaft can be maintained and/or rendered less flexible, or stiffer, by allowing the outer portion to remain thereon. As such, the composite elongate shaft can provide a shaft for a medical device that can include desired characteristics, such as flexibility, torqueability, or the like, along different portions of the shaft.
