Abstract: A device for collecting a biological sample in a patient includes a collection portion having a first axial end portion and a second axial end portion. The second axial end portion has a collapsed position and an expanded position. The second axial end portion moves in an axial direction relative to the first axial end portion when the second axial end portion moves between the collapsed position and the expanded position. The second axial end portion extends axially into the first axial end portion and has a concave shape when in the collapsed position. The second axial end portion is convex when in the expanded position.

Abstract: A device for collecting a biological sample in a subject, the device including an inflatable portion attached to a tubular member, and designed to expand from within the tubular member when inflated and to retract within the tubular member, a surface on the inflatable portion provided with varied thickness to facilitate movement of the inflatable portion between an expanded state and a retracted state, and a plurality of projections on the surface to allow collection of the biological sample when the inflatable portion is in the expanded state.

IPC: A61B10/04
Abstract: A device for collecting a biological sample in an esophagus of a patient includes a swallowable collection portion for collecting a sample at a collection site in the esophagus. A stylet is connected with the collection portion for placing the collection portion into the back of a throat of a patient for swallowing. The device may have a collection portion having a first axial end portion and a second axial end portion. A sleeve is in the first axial end portion. The device may have at least one tissue collecting projection extending from an outer surface of the collection portion; a first side wall of the tissue collecting; a second wall of the tissue collecting projection. A method for collecting a biological sample includes moving the swallowable collection portion with the stylet into the back of a throat of a patient for swallowing.
