Abstract:
1. A surgical tool comprising: an elongated body having a proximal end, a distal end, and an outer surface extending along its length between the proximal and distal ends; first and second sets of tissue approximating structures, wherein each tissue approximating structure comprises a radially deployed position and a radially retracted position relative to the outer surface of 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 outer surface of the elongated body.
