Ablation probe with tissue sensing configuration
First Claim
1. An ablation probe, comprising:
- a housing configured to couple to a microwave energy source;
a shaft extending distally from an interior of the housing and defining a longitudinal axis, the shaft including a radiating section disposed at a distal end portion thereof;
a pair of opposing sensor contacts disposed within the housing, each of the pair of opposing sensor contacts including;
a proximal shaft defining a longitudinal axis extending along the longitudinal axis of the shaft;
a distal shaft extending perpendicularly from the proximal shaft toward the longitudinal axis of the shaft; and
a sensor contact surface disposed on the distal shaft;
at least one sensor having a proximal end portion disposed within the interior of the housing and a distal end portion disposed adjacent the radiating section; and
a pair of sensor contact pads positioned adjacent the proximal end portion of the at least one sensor, the pair of sensor contact pads configured to contact the sensor contact surfaces such that during transmission of microwave energy from the radiating section into target tissue, at least one electrical parameter induced into the at least one sensor is detected by the sensor contact surfaces.

Abstract
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.

20. A handle for an ablation probe, comprising:
-
a housing configured to detachably receive a microwave radiating shaft; a pair of opposing sensor contacts disposed within the housing, each of the pair of opposing sensor contacts including; a proximal portion configured to be coupled to a microwave energy source and defining a longitudinal axis extending along a longitudinal axis of the microwave radiating shaft; a distal portion extending perpendicularly from the proximal portion toward the longitudinal axis of the microwave radiating shaft; and a sensor contact surface movably mounted within the distal portion such that the sensor contact surface moves relative to the distal portion upon the housing receiving the microwave radiating shaft.
