Abstract
A catheter with temperature sensing has a catheter body and a tip section with integrated thermoresistive temperature sensors on its outer surface. The temperature sensor includes a microfabricated thin film assembly of which one layer is a sensor layer of thermoresistive material. In one embodiment, the tip section has a flexible tubing on whose outer surface circumferential temperature sensors are integrated. In another embodiment, the tip section has a tip electrode on whose outer surface a tip temperature sensor is integrated. In yet another embodiment, the tip section has a tip temperature sensor integrated on its tip electrode and multiple circumferential temperature sensors distal of the tip temperature sensor.
