Claim:
1. A method of performing therapy on tissue using a medical apparatus, the method comprising: inserting a shaft of the medical apparatus into tissue of a patient, the shaft being configured for insertion into a hollow anatomical structure (HAS), and the medical apparatus further comprising a sensor and a therapeutic energy application device both located at a distal portion of the shaft, wherein the sensor and the therapeutic energy application device are spaced from each other along a longitudinal axis of the shaft; moving the shaft through the tissue toward the HAS; while inserting or moving the shaft, delivering electrical power to the medical apparatus, directing the electrical power to the sensor, and sensing whether the distal portion of the shaft is located within the HAS; positioning the shaft distal portion at least partially within the HAS; sensing, via the sensor, that the shaft distal portion is positioned at least partially within the HAS; after sensing that the shaft distal portion is positioned at least partially within the HAS, increasing a level of the electrical power delivered to the medical apparatus, the increased level of the electrical power causing the electrical power to be automatically directed to the therapeutic energy application device instead of the sensor; heating the HAS with the therapeutic energy application device.
