CATHETER WITH MULTIFUNCTIONAL MICROINJECTION-MOLDED HOUSING

An electrophysiology catheter has a distal electrode section having a generally-cylindrical, hollow housing body, a lumen and an opening in a sidewall. A flex circuit has a first portion supported on the outer surface the housing body, and a second portion that extends into the lumen via the opening for connection to cables and/or wires in the lumen. The flex circuit has a first and second magnetic field sensing coil traces generally perpendicular to each other and a magnetic field sensing coil wire generally perpendicular thereto is wound around the housing body to form an x/y/z position sensor. One or more ring electrodes are carried on the housing body, separated by ring spacers. A force sensor is mounted on a distal end of the housing body, with strain gauges electrically connected to the flex circuit. The housing is configured to provide a distal anchor for a puller tensile.
