摘要：
A mechanism for removing a fluid-filled object such as an intragastric balloon from a patient. The apparatus includes a delivery tube having a lumen and a retrieval tool able to slide within the lumen that can both puncture and grasp the intragastric balloon. The retrieval tool may have sharpened graspers with either a sharp tip and/or knife-like edges. Alternatively, the delivery tube itself may have sharpened cutting blades that deploy outward to puncture the intragastric balloon. One embodiment utilizes a suction cup tip on the delivery sheath and a sharpened puncture rod that extends past the distal tip of the lumen, for rapid deflation of a balloon. Various embodiments hasten the deflation process and simplify the manipulation required by the surgeon.
