Anastomosis device approximating structure configurations

A surgical tool comprising:

• 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;
• 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 the first set of tissue approximating structures has a different configuration than the second set of tissue approximating structures, and wherein the second set of tissue approximating structures includes at least one extension that is pivotable toward and away from the elongated body.
