APPARATUS TO ELECTROSURGICALLY TREAT ESOPHAGEAL SPHINCTERS

摘要

A sphincter treatment apparatus has an introducer including a distal portion. An expandable device includes a plurality of arms. Each arm of the plurality has a distal section and a proximal section. Each of distal sections of the arm are coupled and each of the proximal sections of the arm are coupled to the introducer distal portion. The expandable device is configured to at least partially dilate a sphincter in a deployed state. An energy delivery device is introduceable from the introducer into a selected site of the sphincter. The energy delivery device is configured to deliver sufficient energy to reduce a frequency of relaxation of the sphincter.
