Abstract
The present invention generally relates to expandable catheters for use in electrophysiology, and more specifically to high-density balloon catheters for use in diagnosing and/or treating cardiac arrhythmias. A catheter includes an elongate catheter shaft comprising a proximal end and a distal end. The elongate catheter shaft defines a longitudinal axis. The catheter includes an expandable assembly having a first delivery configuration and a second deployed configuration. The balloon member includes at least one flexible framework disposed between an outer facing layer and an inner facing layer of the top surface and/or the bottom surface of the balloon member and at least one plurality of electrodes patterned onto the flexible framework. In some embodiments, a flat balloon member includes electrodes on both sides of the planar balloon member. The balloon member may include a flexible structural element disposed within the interior cavity.
