Embodiments of the invention are directed to a medical device and methods of immobilizing and retrieving material from a body. The medical device, in an embodiment, includes an elongated member having a length extending from a distal end to a proximal end, and the elongated member having a first lumen and a second lumen. The medical device further includes a first tube and a second tube extending through the first lumen and the second lumen, respectively, from the proximal end of the elongated member to the distal end of the elongated member. An expandable member is fluidly coupled to a distal portion of each of the first tube and the second tube. The first tube, the second tube, and the expandable member are axially movable relative to the elongated member, and the expandable member is configured for deployment between a collapsed configuration and an expanded configuration.
