    摘要: A rotary variable differential transformer produces a substantially linear output over about 180 degrees of rotation of a rotor core. The transformer includes a base housing having a central bore, and a rotor having a shaft whose angular displacement is to be determined and a generally planar, circular rotor core mounted off-center at one end of the shaft and in a plane normal thereto. The rotor core is rotatably disposed within the opening of the base housing. Also included is a primary coil disposed in the opening of the base housing to circumscribe the shaft at a location rearwardly of the rotor core. First and second windings, with cores, are carried by the base housing and positioned about the base housing opening so that the axes of the coils are oriented radially of the opening and generally in a common plane with the rotor core. The first and second windings are connected together in series opposition. A casing surrounds the sides of the base housing and at least a portion of the rear of the base housing, and includes an opening through which the shaft projects.

    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 three, and may be equal in depth or unequal in depth to provide a steerable or compressible tip.

    摘要: A medical system and device for use in delivering RF energy to a tissue opening and a method for determining an RF dose is disclosed. In one embodiment, the medical device includes an electrode or anchor and one or more devices, such as an impedance electrode, RF electrode and/or thermocouple. The electrode or anchor can be deployed from a delivery shaft inside the left atrium, for example, of a heart and substantially conform to the tissue proximate the tissue opening. Tissue characteristics, such as temperature and/or impedance, can be measured, before, during and after application of RF energy to the tissue, by one or more devices to determine an RF dose. After energy is applied to the tissue between the left and right electrodes, the left electrode can be removed from the left atrium by being received back into the delivery shaft and the delivery shaft thereafter removed from the opening.

    摘要: The present invention is directed to various embodiments of medical devices and methods for occluding a fallopian tube for contraception and permanent sterilization. In one embodiment, the medical device includes an outer member, an inner member and a tissue growth member. The outer member includes an outer surface and an inner surface, wherein the inner surface defines a bore in the outer member. The inner member is configured to be positioned within the bore of the outer member. The tissue growth member is attached to the outer surface of the outer member and is configured to induce tissue growth thereto. With this arrangement, the medical device can be implanted within the fallopian tube and serve as a permanent occluding device therein. If desired, the medical device can be partially removed from the fallopian tube to restore the ability for conception.

    摘要: A medical device for use in delivering RF energy to a tissue opening is disclosed. In one embodiment, the medical device comprises a compliant electrode. The compliant electrode can include a shape memory material, such as NITINOL, to facilitate the electrode having at least one relaxed orientation. The electrode can be deployed from a delivery shaft inside the left atrium, for example, of a heart through the delivery shaft. The electrode can be configured to substantially conform to the tissue proximate the tissue opening. After energy is applied to the tissue between the left and right electrodes, the left electrode can be removed from the left atrium by being received back into the delivery shaft and the delivery shaft thereafter removed from the opening.
