Abstract: An apparatus is provided that includes an elongate member having a distal end portion, a proximal end portion, and a medial portion that is disposed between the distal end portion and the proximal end portion. The medial portion is configured to be disposed in a ureter of a patient. The apparatus further includes an expandable member that is coupled to the elongate member. The expandable member has an expanded configuration and a collapsed configuration. The expandable member is further configured to be inserted into the ureter of the patient and configured to contact the ureter to help retain the elongate member in place within the patient.

Abstract: A medical device including an elongate member having a distal end portion, a proximal end portion, and a medial portion disposed between the distal end portion an the proximal end portion. The proximal end portion is configured to be disposed within a bladder of a patient. A portion of the proximal end portion is configured to contact an inner wall of the bladder to help retain the bladder in an expanded configuration.

Abstract: A medical device includes an elongate member and an expandable member. The elongate member has an inner surface and an outer surface. The inner surface defines a lumen. The elongate member has a collapsed configuration and an expanded configuration and is biased to its collapsed configuration. The expandable member is coupled to the outer surface of the elongate member. The expandable member is configured to move the elongate member from its collapsed configuration to its expanded configuration.

Abstract: 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.
