Device and method for treatment of gastroesophageal reflux disease
First Claim
1. A method to tone or tighten a sphincter, the method including;
- inserting an energy transmitting device located at a distal end of an insertion device into a body opening;
positioning the energy transmitting device in proximity of the sphincter via the insertion device; and
transmitting energy from an energy source through the insertion device to the energy transmitting device for radiation onto the sphincter tissue, wherein the level of energy generated and transmitted by the energy source heats sphincter tissue to a temperature of between 50°
C. and 70°
C. within a time period of between about 1 microsecond to 1 minute to cause collagen shrinkage and tissue tightening.

Abstract
A lower esophageal sphincter tightening device for treating gastroesophageal reflux disease which includes an insertion device, an energy source, and an energy transmitting device. The insertion device, by insertion through a body opening, positions the energy transmitting device in the proximity of the lower esophageal sphincter. The energy source generates and transmits energy via the insertion device to the energy transmitting device which directs the transmitted energy onto the lower esophageal sphincter which is comprised largely of collagen. The energy source transmits energy at a level sufficient to cause heating of the sphincter'"'"'s collagen resulting in a shrinkage of the collagen and a tightening of the sphincter.

7. A method to treat gastroesphageal reflux disease, the method including:
-
inserting an inflatable balloon located at a distal end of an insertion device into a patient'"'"'s esophagus; positioning an antenna associated with the balloon adjacent a target area of tissue which affects operation of a lower esophageal sphincter; inflating the balloon through the insertion device from an inflation device at the proximal end of the insertion device to maintain the position of the balloon and the antenna relative to the target area of tissue; and transmitting energy to the antenna through the insertion device from an energy source at the proximal end of the insertion device for radiation onto the target area of tissue to alter the tissue as controlled by the inflated balloon. - View Dependent Claims (8, 9, 10)
