1. A method of using a suction device to remove an object from a subject's body, the suction device including an expandable suction head at a distal end of a conduit, comprising:
extending the suction device into the body through a lumen of a medical device;
expanding the suction head from a contracted configuration to an expanded configuration within the body;
applying suction to move the object into the expanded suction head;
preventing the object from moving proximally beyond the expanded suction head with a filter positioned at a junction between a proximal end of the suction head and the distal end of the conduit; and
removing the suction device with the object from the body.
