Patent ID: 7783358

Claim:
A device for ablating a vagal nerve to disrupt a function of the vagal nerve to reduce obesity comprising: an energy delivery device; a platform adapted to carry the energy delivery device, the platform being adapted to position the energy delivery device along a first axis and a second axis, the first axis being a longitudinal axis of the esophagus and the second axis being a radius of the esophagus, wherein the platform adjusts the position of the energy delivery device along the first axis to control the focus of the energy being delivered to the location of the vagal nerve branch; a position actuator coupled to the platform, the position actuator moving the platform to adjust the position of the energy delivery device along the first axis, wherein the platform and the position actuator interact through at least one guide rail, and an actuator for energizing the energy delivery device such that energy is delivered to a vagal nerve branch at a level sufficient to ablate the vagal nerve branch.
