Abstract
An electrophysiology catheter includes an elongate catheter body having an elastically-deformable distal region predisposed to assume a spiral shape and a first plurality of electrodes disposed thereon. Each of the first plurality of electrodes includes an electrically active region limited to the inner surface of the spiral shape for use in non-contact electrophysiology studies. A second plurality of electrodes may also be disposed on the distal region interspersed (e.g., alternating) with the first plurality of electrodes, with each of the second plurality of electrodes having an electrically active region extending into the outer surface of the spiral shape for use in contact electrophysiology studies. The distal region may be deformed into a straight configuration for insertion into and navigation through the patient's vasculature, for example via use of a tubular introducer. As the distal region deploys beyond the distal end of the introducer, it resumes the spiral shape.
