摘要： An embolic protection device for use in medical, veterinary, non-medical or industrial applications where removal of an obstruction from a small diameter vessel or vessel-like structure could produce particles, which, if allowed to remain in the vessel, could cause undesirable complications and results. One embodiment comprises a catheter for insertion into a vessel and a trap operably connected to the catheter and to a rotatable member. Rotating the rotatable member relative to the catheter actuates the trap. One embodiment comprises a rotatable member that actuates a flexible strut between an arcuately expanded position and a helically twisted position, and a membrane operably connected to the flexible strut.

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, bearing-free, seal-free rotary impeller levitated by localized opposed, repulsive, permanent magnetic forces and by fluid forces, or by localized opposed repulsive magnetic forces only. Levitation by localized opposed magnetic or magnetic and 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 in pumping of physiological fluids such as blood. The levitating forces of the present invention are applied repulsively both axially and radially with respect to the impeller and are auto-adjusting, such that any attempted displacement of the impeller will automatically incur a corrective change in levitating forces. The invention should be of use in numerous medical and non-medical applications where the benefits of impeller levitation by localized forces are apparent.
摘要翻译：公开了一种具有旋转叶轮的流体泵，其包括通过局部相对的，排斥的，永久的磁力和流体力悬浮的电磁驱动的无轴承的无密封的旋转叶轮，或仅通过局部相对的排斥磁力。通过由电磁力驱动的叶轮的局部相对的磁力或磁力和流体力的悬浮消除了对驱动机构中的轴承和密封的需要。这避免了与其他泵送机构相关的热积聚和泄漏，这在泵送诸如血液的生理液体中是重要的。本发明的悬浮力相对于叶轮沿轴向和径向排斥地施加，并且是自动调节的，使得叶轮的任何尝试的位移将自动地引起浮力的校正变化。本发明应用于许多医疗和非医疗应用，其中通过局部力量的叶轮悬浮的益处是显而易见的。

摘要： A fluid pump with a rotary impeller is disclosed which comprises an electromagnetically-driven, bearing-free, seal-free rotary impeller levitated by localized opposed, magnetic forces and by fluid forces, or by localized opposed magnetic forces only. Levitation by localized opposed magnetic forces alone or by a combination of magnetic and 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 in pumping of physiological fluids such as blood. The levitating forces of the present invention are applied both axially and radially with respect to the impeller. The magnetic forces are provided by a combination of diamagnets or solenoids, opposed by permanent magnets, solenoids or electromagnets. The invention should be of use in numerous medical and non-medical applications where the benefits of impeller levitation by localized forces are apparent.

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.
