  • Blood pump
    Patent number: 6245007
    Abstract: A blood pump comprising a pump mechanism having an outer sleeve, an inner sleeve, and an impeller. The pump mechanism is movable between a closed and preferably retracted position wherein one or both of an inlet port and an outlet port are sealed by the inner and/or outer sleeve for inserting the pump mechanism into the heart, and an open and preferably extended position wherein the inlet and outlet ports are open to allow the impeller to pump blood through the ports. The pump mechanism preferably retracts so that it has less length and is more readily maneuvered when it is in its closed position. Also disclosed are a bearing portion received within a cap of the impeller with a flow of lubricating liquid between the bearing portion and cap, and a method of using the pump.

  • Guidance system for a moving person
    Patent number: 5917326
    Abstract: The guidance system of the invention includes at least two spaced, permanently magnetized regions that each produce a magnetic field. The two permanently magnetized regions can be provided at either side of another region that produces a magnetic field of less intensity than the permanently magnetized regions, and in one embodiment, the former region produces no magnetic field. The system may also include portable means for detecting the magnetic fields produced by the permanently magnetized regions, and that sensor may be mounted to a cane for use by a person. In another embodiment, the permanently magnetized regions contrast with either each other or the region that produces a magnetic field of less intensity, or have different surface characteristics, or both.

  • Conformable magnetic articles underlaid beneath traffic-bearing surfaces
    Patent number: 5853846
    Abstract: A conformable magnetic article for underlayment beneath a traffic-bearing surface which sends a magnetic signal to a sensor traveling over the traffic-bearing structure. The magnetic article comprises at least one conformable magnetic layer comprising a binder and a sufficient amount of magnetic particles dispersed within the binder to provide a magnetic signal through the traffic-bearing structure to a sensor.
