Patent ID: 8538501

Claim:
A cardiac mapping and ablation catheter system comprising: a radio frequency ablation source comprising an output; a mapping device; a catheter comprising three or more catheter electrodes arranged along a length of the catheter, wherein the three or more catheter electrodes are spaced apart from each other along the length of the catheter, wherein two of the three or more catheter electrodes are electrically coupled to the mapping device, and wherein one catheter electrode of the three or more catheter electrodes is not electrically coupled to the mapping device; and a plurality of capacitive components, wherein all of the three or more catheter electrodes are electrically coupled to the output of the radio frequency ablation source through a capacitive component of the plurality of capacitive components such that energy delivered to each capacitive component by the radio frequency ablation source passes through the plurality of capacitive components to all of the three or more catheter electrodes.
