Abstract: A method and system capable of identifying ectopic foci, rotors, or conduction pathways involved in reentrant arrhythmias within cardiac tissue, and then treating identified ectopic foci, rotors, and/or pathways with either lethal or sub-lethal temperatures. The system includes a medical device having one or more mapping elements and one or more treatment elements, and a computer programmable to identify ectopic foci and rotors based at least in part on signals received from the one or more mapping elements at one or more locations.

Abstract: The present invention relates to a method, device, and system for improved mapping and/or ablation of a tissue. The device may generally include an elongate body and a distal assembly affixed to the elongate body that includes a treatment electrode having a conductive mapping region and a selectively conductive ablation region that is conductive of high-frequency current and substantially non-conductive of low-frequency current. Alternatively, the device may generally include a treatment electrode having a conductive mapping or ablation region and a region that is coated with an electrically insulated but thermally conductive layer.

Abstract: A catheter including a proximal end and a distal end. An expandable element coupled to the distal end is included, the expandable element including a proximal portion and a distal portion, the expandable element defining an exterior surface. A first plurality of electrodes coupled to the exterior surface of the distal portion of the expandable element are included, each of the first plurality of electrodes being selectively operable to transmit unipolar radiofrequency energy. A second plurality of electrodes coupled to the exterior surface of the proximal portion of the expandable element are included, each of the second plurality of electrodes being selectively operable to transmit bipolar radiofrequency energy.
