摘要：
A sphincter treatment apparatus includes an energy delivery device introduction member including a proximal end with a first radius of curvature and a distal end with a second radius of curvature. The introduction member is configured to be introduced into the sphincter in a non-deployed state and to be expanded to a deployed state to at least partially expand the sphincter or an adjoining structure. An energy delivery device is coupled to the introduction member. A retainer member is coupled to the energy delivery device introduction member and configured to controllably position the introduction member in an orifice of the sphincter.
