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.
