  • Impedance computation for ablation therapy
    Patent number: 9668803
    Abstract: This disclosure describes impedance computation techniques that may reduce the effect of crosstalk, thus generating more accurate impedance measurements. In particular, an ablation system models the electrical interaction among the active electrodes and a common return electrode using a star-configuration resistor model. The ablation system computes one or more parameters of the star-configuration resistor model and adjusts the therapy based on at least the computed parameters of the star-configuration resistor model.
    Type: Grant
    Filed: August 7, 2014
    Date of Patent: June 6, 2017
    Assignee: Medtronic, Inc.
    Inventors: Nikhil Bhushan, Thomas R. Skwarek, Graham Spall, Keith S. Bosacker
