FIBER OPTIC TEMPERATURE SENSOR FOR COOLED RADIOFREQUENCY PROBE

摘要

A medical probe assembly for delivering energy to a patient's body includes at least one probe having an elongate member with a distal region and a proximal region. The distal region includes an electrically non-conductive outer circumferential portion. The probe assembly also includes an electrically-conductive energy delivery device extending distally from the electrically non-conductive outer circumferential portion. The energy delivery device includes a conductive outer circumferential surface and one or more internal lumens configured for circulating a cooling fluid to a distal end of the energy delivery device. The probe assembly also includes a protrusion extending from the distal end of the energy delivery device. The protrusion is electrically coupled to the energy delivery device and includes a temperature sensing element extending from a distal end of the energy delivery device. The temperature sensing element includes at least one optical fiber extending therethrough such that a distal-most end thereof is exposed to define a temperature sensing face.
