摘要： A rotary pump mechanism is disclosed which comprises a coupling section that couples an impeller and drives the coupling section and, in turn, the impeller. The coupling section incorporates most of the components of the pump that wear out and are expensive. As a result, the impeller can be disposed of without disposing of other components. The coupling section can also be changed for continuous operation of a single impeller. Although the preferred application of the invention is in the area of pumping blood and other biological fluids, the disclosed invention has utility in any application where it is desirable to turn an "impeller-like" element.

摘要： Pumps wherein smooth surfaced rotators cause propulsion of a delicate fluid without significant damage to the fluid. The pumps may be used as heart pumps, blood pumps, and pumps for all types of fluids in connection with the maintenance of life or biological functions in a human or animal subject in many in vivo, ex vivo, or in vitro applications, or for any other application requiring gentle handling. The pumps may be actuated by internal or external electric motors, and the rotators may be configured to converge mutually as an inverse function of distance from the axis of the rotators. The rotators may be connected together, by pins passing through the fluid passages, for mounting and driving as a unit, or may be mounted and driven independently to further eliminate the possibility of damage to the fluid by rotator-connection members.
摘要翻译：其中光滑的浮雕旋转器引起精细流体的推进而对流体没有显着的损害。在许多体内，离体或体外应用中，泵可以用作所有类型的流体的心脏泵，血泵和泵，用于在人或动物受试者中维持生命或生物功能，或用于任何其他需要温和处理的应用程序。泵可以由内部或外部电动机来驱动，并且转子可被构造成相互转动，作为与转子轴线的距离的反函数。旋转器可以通过穿过流体通道的销连接在一起，用于作为一个单元的安装和驱动，或者可以独立地安装和驱动，以进一步消除由旋转器连接构件损坏流体的可能性。

摘要： An angioplasty device and particle trap for use in removal of a particle from a small diameter vessel or vessel-like structure is disclosed. One embodiment includes a catheter for insertion into a vessel-like structure, the catheter having a catheter wall and a movable member, a trap operably connected to the catheter wall and to the movable member, wherein relative motion between the catheter wall and the movable member actuates the trap. In one embodiment, the expanded trap is formed from struts in a spiral-shaped configuration. In one embodiment, the contracted trap forms a waist to creates a pinch-point to trap particles. In one embodiment, the contracted trap forms a cocoon-like structure to further trap particles. In one embodiment, the angioplasty device includes a handle to actuate the trap from a contracted position to an expanded position and return to a contracted position. The handle provides rotational or longitudinal or both types of movement to actuate the trap.

摘要： A fluid pump with rotary impeller is disclosed which comprises an electromagnetically driven rotary impeller levitated by localized opposed fluid forces. Levitation by localized opposed fluid forces of an impeller driven by electromagnetic forces eliminates the need for bearings and seals in the driving mechanism. This avoids the heat build-up and leakage associated with other pumping mechanisms, which can be of importance for pumping of physiological fluids such as blood. The levitating fluid forces of the present invention are auto-adjusting, such that any attempted displacement of the impeller will automatically incur a corrective change in levitating fluid forces. However, fluid force sensors and regulators could be incorporated into the present invention if desired. The invention should be of use in numerous medical and non-medical applications where the benefits of impeller levitation by localized fluid forces are apparent.
