Patents by Inventor Kenneth H. Drew

Kenneth H. Drew 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).

  • Contact sensor and sheath exit sensor
    Patent number: 9198601
    Abstract: A system and method is provided that allows for determining the local impedance of one or more electrodes of an electrode catheter. Such local impedance may be utilized to identify the relative position of an electrode catheter to a sheath of a guiding introducer. In another arrangement, local impedance of a catheter electrode can be utilized to calibrate a catheter electrode to provide improved contact sensing.
    Type: Grant
    Filed: March 6, 2015
    Date of Patent: December 1, 2015
    Assignee: St. Jude Medical, Atrial Fibrillation Division, Inc.
    Inventors: John A. Hauck, Jeffrey A. Schweitzer, Kenneth H. Drew
