    摘要: An apparatus includes a first expandable member that is expandable by an expansion medium. The first expandable member includes an exterior and a plurality of apertures. The expansion medium is released from the first expandable member when a sufficient pressure is applied to the expansion medium housed in an interior of the first expandable member. A second expandable member is positioned at least partially adjacent to the first expandable member. The second expandable member is configured to receive at least a portion of the expansion medium from the interior of the first expandable member. An electromagnetic energy delivery device is coupled to one of the first or second expandable members and is configured to be coupled to a power source. The first and second expandable members are sized to be expanded sufficiently to open a sphincter.
