Abstract:
1. A method of treating tissue comprising: determining a depth of target tissue to be treated based on a depth within a first body cavity; adjusting a position of a measuring element of a probe so that a distance along an axis of the probe between a contacting surface of the measuring element and a treatment element of the probe substantially equals the depth of the target tissue within the first body cavity, wherein the measuring element includes a plurality of tissue contacting surfaces separated from one another by a desired angle, each tissue contacting surface defining a desired angular orientation of the probe within the second body cavity; locking a locking element in a desired position relative to the probe; advancing the probe into a second body cavity separate from the first body cavity until the contacting surface of the measuring element contacts tissue at an opening to the first body cavity, preventing further insertion of the probe into the second body cavity; and operating the treatment element.
