ABLATION PROBE WITH TISSUE SENSING CONFIGURATION

摘要

An ablation probe is provided. The ablation probe includes a housing that is configured to couple to a microwave energy source. A shaft extends distally from the housing and includes a radiating section at a distal end thereof. A sensor assembly is operably disposed on the housing and includes a pair of sensor contacts. One or more sensors are positioned adjacent the radiating section and extend along the shaft. The sensor(s) have a pair of sensor contact pads that are positioned on the shaft for contact with the pair of sensors such that during transmission of microwave from the radiating section into target tissue at least one electrical parameter is induced into the at least one sensor and detected by the pair of sensor contacts.

1. An ablation probe, comprising:
a housing configured to couple to a microwave energy source; a shaft extending distally from the housing, the shaft including a radiating section at a distal end thereof; a sensor assembly operably disposed within the housing and including a pair of sensor contacts; and at least one sensor positioned adjacent the radiating section and extending along the shaft, the at least one sensor having a pair of sensor contact pads positioned on the shaft for contact with the pair of sensors such that during transmission of microwave energy from the radiating section into target tissue at least one electrical parameter is induced into the at least one sensor and detected by the pair of sensor contacts.
