Abstract
Official abstract text for this publication.
A method of performing therapy on tissue using a medical apparatus. The apparatus includes a shaft configured for insertion into a hollow anatomical structure (HAS) and has a tissue sensor and a therapeutic energy application device both located on the shaft. The method comprises: receiving electrical power at a first power level and directing the first-level power to the tissue sensor and not to the therapeutic energy application device, thereby enabling tissue sensing with the tissue sensor; receiving electrical power at a second power level higher than the first-level power; and, in response to receipt of the second-level power, directing the second-level power to the therapeutic energy application device, thereby enabling performance of therapy on the tissue with the therapeutic energy application device. Additional methods and apparatus are disclosed as well.
First claim
Opening claim text (preview).
What is claimed is: 1. Apparatus for performing therapy on tissue, the apparatus comprising: an elongate shaft having a distal portion configured for insertion into a hollow anatomical structure (HAS); a power lead; a sensor located at the shaft distal portion and configured to receive power through the power lead at a relatively low sensing level to determine which medium the sensor is in contact with; a therapeutic energy application device located at the shaft distal port…
