    摘要： Pompe à liquide (10) dotée d'une roue hélice rotative (16) comprenant une roue hélice rotative à entraînement électromagnétique (30) soulevée par lévitation par des forces de fluide opposées localisées. La lévitation par des forces (52) de fluide opposées localisées d'une roue hélice entraînée par des forces électromagnétiques élimine les supports et les joints dans le mécanisme d'entraînement. Cet agencement évite l'accumulation de chaleur ainsi que les fuites associées à d'autres mécanismes de pompage pouvant avoir de l'importance dans le pompage de liquide physiologique tel que le sang. Les forces de lévitation du fluide selon l'invention se règlent automatiquement, de sorte que tout déplacement entrepris de la roue hélice entraînera automatiquement un changement correcteur des forces de lévitation du fluide. Toutefois, des capteurs de forces du fluide ainsi que des régulateurs peuvent être mis en oeuvre dans l'invention. L'invention trouve une utilisation dans de nombreuse applications médicales et non médicales dans lesquelles les avantages de la lévitation de roue hélice par des forces de fluide localisées sont manifestes.

    摘要： An over-the-wire angioplasty device and particle trap 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 (26) for insertion into a vessel like structure, the catheter having a catheter wall and a moveable member, a trap (38) operably connected to the catheter wall and to the moveable member, wherein relative motion between the catheter wall and the moveable member actuates the trap. The catheter in this embodiment defines a guidewire lumen adapted to slideably receive a guidewire (fig. 2). Some embodiments also include a selective coupling device.

    摘要： A rotary pump mechanism (1) which is comprised of a coupling section (2) that couples an impeller (7) and a driving member (16) for driving the coupling section and, in turn, the impeller. The coupling section incorporates most of the components (19, 30) 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： A fluid pump with a rotary impeller is disclosed which comprises an electromagnetically-driven, bearing-free, seal-free rotary impeller (16) 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 (70, 70', 75, 75'), opposed by permanent magnets, solenoids or electromagnets (70, 70', 75, 75'). 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： An angioplasty device is disclosed for treatment of, or for compression and/or removal of an obstruction from, a vessel or vessel-like structure in medical, non-medical and industrial applications. The device incorporates a trap/barrier (6) for trapping and removing particles that break away from the treatment site with traditional angioplasty devices including but not limited to balloons, cutting rotors, fiber meshes, lasers and the like. The device also provides means (13, 14) for removing the trapped particles from the treated vessel. An angioplasty device is also disclosed that incorporated only the trap/barrier (6) and particle removal elements of the previously described device. A method for treatment of, or for removal or compression of an obstruction in, a vessel or vessel-like structure is disclosed that utilizes an angioplasty device of the instant invention. A method employing an angioplasty device of the instant invention is also disclosed for preventing particles from escaping from a point of manipulation of vessel or vessel-like structure.
