Patent ID: 8475448

Claim:
A catheter comprising: a catheter body having proximal and distal ends; a tip section at the distal end of the catheter body, the tip section comprising a plurality of temperature sensors on an outer surface of the tip section, wherein each of the temperature sensors comprises a contact layer and a thin film sensor layer, the thin film sensor layer having a film thickness of about 500 nm or less, the tip section further comprising at its distal end a tip electrode, wherein the plurality of temperature sensors comprises: at least one tip temperature sensor on at least a portion of an outer surface of a distal-most tip end of the tip electrode, and at least one circumferential temperature sensor extending circumferentially about 10 to 120 degrees around the outer surface of the tip section, wherein a first circumferential temperature sensor is on an outer circumferential surface of the tip electrode, wherein the contact layer of the at least one tip temperature sensor is embedded in the outer surface of the distal-most tip end of the tip electrode, and the thin film sensor layer of the at least one tip temperature sensor is on the contact layer and the outer surface of the distal-most tip end of the tip electrode.
