    摘要： A volumetric pump and fluid control valve system for controlling the flow of fluid which comprises a housing containing an interior cavity, an elongated valve shaft is disposed inside the cavity, and an elongate drive shaft of smaller diameter than the valve shaft connected to one end of the valve shaft. The drive shaft passes through a passage formed in the housing to extend from the cavity to the exterior. A resilient sheet of material having an aperture is disposed in the housing on the exterior side of the passage and the drive shaft passes through the aperture to form a sphincter seal. The drive shaft can be used to move the valve shaft back and forth in a reciprocating motion producing positive and negative pressures causing fluid to flow or merely to stabilize the valve shaft in position. The valve shaft includes two flanges which are spaced apart from one another. The flanges extend at least partially around the circumference of the valve shaft. The drive shaft is disposed in the cavity above the valve shaft and substantially parallel thereto. A tab extends downwardly from the piston sufficiently far to abut either of the flanges when the piston is moved longitudinally a sufficient distance.

    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.
