Abstract
An electrophysiology catheter includes an elongated support member with shape-memory as a first composite component and an elongated outer tubing as a second composite component, the support member defining a longitudinal axis of the catheter, the support member including a distal portion with a plurality of single-axis sensors, and the elongated outer tubing generally coextensive with the elongated support member, the tubing including a side wall surrounding a lumen through which the support member extends and joins with the outer tubing to form a catheter, the tubing including conductive wires embedded in the side wall and ring electrodes on an outer surface of the side wall, each ring electrode in conductive contact with a respective conductive wire.
