Abstract
In one embodiment, an endoscope has a proximal end portion opposite a distal end portion. A view port is included at the distal end portion to view an internal body region through a passageway of a patient's body. Also located at the distal end portion are one or more piezoelectric elements operable in one mode to determine position of the distal end portion relative to internal body region and operable in a second mode to ablate tissue of the internal body region. The endoscope carries a balloon positioned about the one or more piezoelectric elements to selectively hold the distal end portion in a desired position in the passageway.
