ABSTRACT:
A medical probe apparatus comprising a catheter having a stylet guide housing with one or more stylet ports therein and stylet guides for directing one or more flexible stylets outward through respective stylet ports and through intervening tissue to target tissue. The active stylets emit radio frequency RF energy which establishes an RF current in the patient. The current, being densest at the stylet tips, causes heating of the surrounding tissue to initiate ablation of the target tissue. One aspect of the invention includes temperature sensing stylets at the location of the RF emitting stylets to monitor the temperature of the tissue being ablated. This allows the surgeon to have increased knowledge about the abating action under way in order to control the intensity of the applied RF current, or to adjust the amount of time the current is applied, or both. Further included herein is a plurality of temperature sensors mounted on an ultrasound probe to be used to monitor tissue temperature at the ultrasound probe while allowing the ultrasound device to monitor the position and orientation of the medical probe apparatus of the present invention.
