Abstract:
1. An electrophysiology catheter, comprising: an elongate catheter body comprising an elastically-deformable distal region, wherein the distal region is configured to assume a first collapsed state and a second expanded state, and wherein the distal region assumes a spiral shape in the expanded state, and further wherein the spiral shape comprises an inner surface on an inside of the spiral shape configured not to contact tissue and an outer surface on an outside of the spiral shape capable of contacting tissue when in the expanded state, the distal region terminating in a distal tip; and a plurality of electrodes disposed on the distal region, each of the plurality of electrodes comprising an electrically active region, wherein there are no electrically active regions on the outer surface of the spiral shaped portion of the distal region.
