- an elongated body having a proximal end, a distal end, an outer cylindrical surface, and a longitudinal axis extending from the proximal end to the distal end;
first and second sets of tissue approximating structures having a retracted position relative to the elongated body in which the tissue approximating structures of the first and second sets do not extend past the outer surface of the elongated body, and a deployed position relative to the elongated body in which at least one of the tissue approximating structures of each of the first and second sets extends from the outer surface of the elongated body at an angle relative to its longitudinal axis;
an actuating mechanism at the proximal end of the elongated body for independently deploying and retracting each of the first and second sets of tissue approximating structures;
a drainage lumen extending from a drainage aperture at the distal end of the elongated body to the proximal end; and
a main balloon adjacent to the distal end of the elongated body;
wherein each of the first and second sets of tissue approximating structures includes at least one elongated tine having a distal end, and wherein the second set of tissue approximating structures comprises an enlarged shaped element at the distal end of at least one of its elongated tines.

Abstract
A surgical tool including an elongated body having a proximal end and a distal end, first and second sets of tissue approximating structures having deployed and retracted positions relative to the elongated body, an actuating mechanism at the proximal end of the elongated body for independently deploying and retracting each of the first and second sets of tissue approximating structures, and a drainage lumen extending from a drainage aperture at the distal end of the elongated body to the proximal end. The tool further includes a main balloon adjacent to the distal end of the elongated body, wherein the first set of tissue approximating structures has a different configuration than the second set of tissue approximating structures.
