Zusammenfassung:	Apparatuses and methods are disclosed for reducing the size of openings within a heart valve or other opening in the wall of a body lumen by implanting an elastically expanded member around the opening and then permitting the expandable member to contract. The expandable member may encircle a portion of an inflatable member, the distal end of which is inserted through the opening along with the expandable member. The inflatable member is inflated to expand the expandable member and then drawn proximally form the opening to drive projections formed on the expandable member into the valve or wall. The inflatable member is then withdrawn, allowing the expandable member to elastically contract. The inflatable member may have first and second stages, where the second stage is distal of the first stage and has a larger inflated diameter.
