Bruce J. Shook has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • TAPERING STENT
    Publication number: 20220287859
    Abstract: A stent includes a high radial force segment and a highly flexible segment, where the diameters of the high radial force segment and the highly flexible segment are different. For example, the stent may be formed from a tube having varying diameters as it extends distally combined with increased strut density to achieve increased flexibility distally while reducing loss of radial stiffness. The stent may further be placed with an additional stent segment, where the additional stent segment has a radial force similar to the radial force of the highly flexible force segment.
    Type: Application

  • Method and apparatus for applying asymmetric biphasic truncated exponential countershocks
    Patent number: 5083562
    Abstract: A method and apparatus for applying an asymmetric biphasic exponential waveform countershock to the heart useful in an implantable cardioverter or defibrillator, wherein the second phase has a start amplitude of substantially one half that of the first phase, and wherein the polarity of a capacitor discharging through a current path including the heart is reversed. A voltage reversing circuit may include a voltage shifter which shifts voltage associated with switching elements in the circuit to reduce voltage stresses in the switching elements.
