Method to treat esophageal sphincters

摘要

A method of treating a sphincter provides a treatment apparatus that includes an expandable device coupled to an introducer distal portion and an energy delivery device. The expandable device includes a first arm and a second arm each with proximal and distal section. The expandable member has a non-deployed configuration and a deployed configuration when the first and second arm distend away from each other. The expandable device is at least partially introduced in the sphincter. At least a portion of the energy delivery device is advanced from the expandable device into an interior of the sphincter. Sufficient energy is delivered from the energy delivery device to create a desired tissue effect in the sphincter. The expandable device is then removed from the sphincter.
