Abstract
A mechanism for removing a fluid-filled object from a patient. The apparatus includes a deflation tube with a puncture member at one end of the tube for piercing a hole in the object wall. The apparatus includes a retrieval mechanism slidable within the deflation tube lumen. The retrieval mechanism includes an expansion element that is expandable when positioned within the object from a first configuration with a dimension less than that of the deflation tube lumen to a second or deployed configuration with a dimension that is greater than an outer dimension of the puncture member. The expansion element contacts an inner surface of the inflatable object as the deflation tube and retrieval mechanism are withdrawn from the body cavity. The expansion element may be a T-bar, a foldable anchor, an inflatable member, or another expandable form.
