  • Oxygen sensing pacemaker
    Patent number: 4903701
    Abstract: A demand pacemaker which regulates its pacing rate based upon sensed oxygen saturation percentage. The pacemaker employs a two wavelength reflectance oximeter as a sensor. The sensor includes an oscillator which sequentially activates red and infrared diodes. The duty cycle of the oscillator is regulated by the relative amounts of red and infrared light reflected by the blood. The construction of the sensor allows the sensor to operate with only two conductors, optimizing it for incorporation in a standard, bipolar pacing lead.
    Type: Grant
    Filed: March 10, 1988
    Date of Patent: February 27, 1990
    Assignee: Medtronic, Inc.
