Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 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 outsi…
