Claim:
A method for evacuating and removing a fluid-filled object positioned in a body cavity of a patient, comprising: positioning an aspirator device in the body cavity; piercing a wall of the fluid-filled object with the aspirator device, wherein the aspirator device comprises a tube with a lumen; sliding a retrieval mechanism in the lumen of the tube, wherein the retrieval mechanism comprises a deployment member and an expansion element pivotally coupled to an end of the deployment member, the expansion element having a deployed configuration greater in size than an outer diameter of the tube and wherein the sliding comprises extending the expansion element at least partially out of the lumen and into the pierced wall of the object; expanding the expansion element to the deployed configuration by extending the expansion element at least partially out of the lumen, the expansion element expanding to the deployed configuration when emerging from the lumen of the tube; and withdrawing the retrieval mechanism and the aspirator device from the body cavity, wherein during the withdrawing the expansion element contacts an inner surface of the wall of the object, forcing the object to be removed from the body cavity with the retrieval mechanism.
