  • Patent number: 6801798
    Abstract: A member-illuminating cuff for measurement of systolic, mean and diastolic pressure, oxygen saturation, pulse and respiratory rate in small body members, comprising a hinged cuff housing, one or more light sources mounted on a first section of the housing, a photodetector mounted on a second section of the housing, and a disposable, inflatable cuff adapted to fit within the cuff housing and around a body member placed therein.
    Type: Grant
    Filed: June 20, 2002
    Date of Patent: October 5, 2004
    Assignee: Purdue Research Foundation
    Inventors: Leslie A. Geddes, Kirk S. Foster, William E. Schoenlein, Rebecca A. Roeder, Claude B. Harrington

  • Patent number: 5916239
    Abstract: A closed-loop, variable-frequency, vagal-stimulation apparatus for control of ventricular rate during atrial fibrillation. In one embodiment the apparatus includes a stimulator applied to the left vagus nerve and a controller programmed to automatically and continuously adjust the vagal stimulation frequency as a function of the difference between actual and desired ventricular excitation rates. In a second embodiment the apparatus includes a vagal nerve stimulator and a controller which automatically adjusts the vagal stimulation frequency as a function of the difference between ventricular excitation rate and arterial pulse rate in order to eliminate or minimize pulse deficit.
    Type: Grant
    Filed: November 24, 1997
    Date of Patent: June 29, 1999

  • Patent number: 5690681
    Abstract: A closed-loop variable frequency vagal stimulation apparatus for control of ventricular rate during atrial fibrillation. In one embodiment the apparatus includes a stimulator applied to the left vagus nerve and a proportional controller programmed to automatically and continuously adjust the vagal stimulation frequency proportionally as a function of the difference between actual and desired ventricular excitation rates. In a second embodiment the apparatus includes a vagal nerve stimulator and a controller which automatically adjusts the vagal stimulation frequency as a function of the difference between ventricular excitation rate and arterial pulse rate in order to eliminate or minimize pulse deficit.
