Abstract
Apparatus and methods for treating tissue at or near a sphincter provide for transluminal introduction of an energy delivery device. The device includes a tissue compression member to compress target tissue at or near the sphincter. A radiofrequency energy source is coupleable to the delivery device to deliver radiofrequency energy to the target tissue. Energy is delivered to heat the tissue to a desired temperature. The desired temperature is selected to induce an injury-healing response or to inducing shrinkage of collagen fibers in the target tissue to thereby reduce laxity in the target tissue.
