1. A deflation device, comprising, in combination:

  • an endoscope tube, having a distal end, a proximal end, and a lumen;

    a cap disposed at the distal end of the endoscope tube and having walls defining a balloon interface chamber;

    a coring device disposed within the lumen and configured to travel within the lumen such that a distal end of the coring device is extendable beyond the distal end of the cap;

    wherein the cap further comprises a protrusion extending radially inward from the walls of the cap, the walls defining a coring channel; and

    wherein the protrusion is configured to guide the coring device to an orientation orthogonal to a surface of a balloon at a site of penetration.
