摘要： Surgical forceps are disclosed which consist of first and second legs attached at one end in a tweezer-like configuration. One of the legs includes a small conduit which terminates in one or more inlets disposed on the inner and outer surface of the tweezers. The opposite end of the conduit is adapted for connection to a source of vacuum to permit fluid to be drawn away from a surgical area. In an alternative embodiment, a similar conduit is formed in the other forceps leg which is adapted for connection to liquid under pressure, terminating in one or more openings on the inner and outer surface of the tweezer legs to permit cleansing of the surgical area. In either embodiment, the conduits are selectively extendable beyond the tip of the forcep leg by movable tubes which allow the suction of fluid supply to reach into areas removed from the forcep leg. Fluid control means are provided on the tweezers for both the vacuum conduit and the liquid supply conduit.

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： 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.
