  • Patent number: 5733313
    Abstract: The implantable, electrically operated medical device system comprises an implanted radio frequency (RF) receiving unit (receiver) incorporating a back-up rechargeable power supply and an implanted, electrically operated device, and an external RF transmitting unit (transmitter). RF energy is transmitted by the transmitter and is coupled into the receiver which is used to power the implanted medical device and/or recharge the back-up power supply. The back-up power supply within the receiver has enough capacity to be able to, by itself, power the implanted device coupled to the receiver for at least 24 hours during continual delivery of medical therapy. The receiver is surgically implanted within the patient and the transmitter is worn externally by the patient. The transmitter can be powered by either a rechargeable or non-rechargeable battery. In a first mode of operation, the transmitter will supply power, via RF coupled energy, to operate the receiver and simultaneously recharge the back-up power supply.

  • Patent number: 5445624
    Abstract: The present invention relates to an improved intravascular catheter. The intravascular catheter involves the use of a progressively compliant tip at the distal end of the catheter body. This progressively compliant tip utilizes an endmost tubular member having a first softness and an intermediate tubular member having a second softness. The low temperature thermoplastic overcoat on the catheter body has a third softness which is significantly lower than the first and second degrees of softness exhibited by the other tubular members. The endmost member, intermediate member and thermoplastic overcoat are joined together by heat formed, blended tubular regions, each having respective incrementally increasing intermediate softness characteristics over predetermined lengths thereof.

  • Patent number: 5423773
    Abstract: The present invention relates to an improved intravascular catheter. One improvement relates to the catheter body wherein the body is made of an inner tube of high temperature thermoplastic having a low coefficient of friction (for example fluorinated polymer). The extruded inner tube carries on its periphery a plurality of gear bodies. Each gear body further includes opposing elongated tangentially extending gear teeth spaced above the periphery of the tube. Wires are wound about the tube and over the gear teeth. An overcoat of low temperature thermoplastic covers the entire catheter and is interstitially disposed beneath the tangential teeth and the gear supported portions of the wire.The overcoat of low temperature thermoplastic over the high temperature fluorinated polymer produces an interlocking gear thereby enhancing the lamination of both low and high temperature polymers. This coupled gear design makes possible a mechanical anchoring to fluorinated polymers such as TEFLON.RTM.

  • Patent number: 4669424
    Abstract: Pests, such as fleas and ticks, are repelled from domestic animals, such as dogs and cats, by attaching an ultrasonic compressional wave energy source to the animal in such a position that a beam of the compressional wave energy is directed downwardly toward a surface on which the animal is located. Energy in the beam is reflected from the surface back to the animal. The energy has sufficient intensity, as reflected back to and incident on the animal, to repel the pests. The energy is pulsed on and off at a relatively low duty cycle at a rate above a predetermined minimum, such that during each pulse the envelope amplitude varies.
