Claim:
1. A device for heating tissue, comprising: a housing sized for insertion through a naturally occurring body orifice to a target location within a lumen; a heat generating element focusing thermal energy on a target area separated from an outside of the housing so that, when the housing is in the target location, the target area is within tissue surrounding the lumen at a predetermined depth from a lumenal wall wherein the heat generating element comprises an array of ultrasound transducers positioned within the housing and an acoustic reflector positioned over an outer surface of the housing and over the array of transducers, the acoustic reflector extending away from the housing in a first direction by a first predetermined distance toward the target area so that acoustic energy from the ultrasound transducers is focused away from the transducers in the first direction by a second predetermined distance greater than the first predetermined distance; a temperature sensing element sensing data corresponding to a temperature of tissue in the target area; and a processor controlling the heat generating element in response to the data sensed by the sensing element.
