  • Mapping and ablation catheter system
    Patent number: 8538501
    Abstract: A mapping and ablation catheter system including a radio frequency ablation source having an output, a mapping device, a catheter, and two or more capacitive components. The catheter may include two or more catheter electrodes, wherein two of the two or more catheter electrodes may be electrically coupled to the mapping device. Each of the two or more catheter electrodes may be electrically coupled to a capacitive component, wherein each capacitive component may be electrically coupled to the output of the radio frequency ablation source such that energy delivered to each catheter electrode of the two or more catheter electrodes passes through the capacitive component.
    Type: Grant
    Filed: January 9, 2009
    Date of Patent: September 17, 2013
    Assignee: Mayo Foundation for Medical Education and Research
    Inventors: Kalpathi Venkatachalam, Samuel J. Asirvatham
