Patents by Inventor Kathleen U. Crandall

Kathleen U. Crandall 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).

  • Medical device function configuration post-manufacturing
    Patent number: 8352038
    Abstract: A medical device system and method configure a medical device according to a configuration definition. The configuration definition includes an allowable status and a function status for each of a number of medical device functions. The medical device configuration is updated automatically in response to being interrogated by a programmer configured to update the device configuration. The device configuration is updated by updating the function status for at least one of the medical device functions in response to the allowable status for the medical device function.
    Type: Grant
    Filed: October 1, 2007
    Date of Patent: January 8, 2013
    Assignee: Medtronic, Inc.
    Inventors: Bor-Jiin Mao, Mark L. Haerle, Kathleen U. Crandall, Patricia K Fuher, Michael Lee Graham

  • System and method for determining remaining battery life for an implantable medical device
    Publication number: 20040039424
    Abstract: A system and method for determining a remaining life estimate of the remaining battery life of a battery of an implantable medical device (IMD). The IMD battery preferably exhibits a highly reproducible monotonically decreasing discharge curve. The estimated remaining life estimates are derived by periodically measuring battery voltage, and estimating the estimated past current drain of the IMD comprising an average of the sum of the quiescent current drain and therapy delivery current drain, and determining the estimated remaining longevity from the measured voltage and the estimated past current drain.
