Abstract: A balloon catheter visualization device includes a handle, an elongate shaft, and an asymmetrical balloon. The elongate shaft includes a distal end, a proximal end, and defines a lumen and a longitudinal axis extending from the proximal end to the distal end. The proximal end is coupled to the handle. The asymmetrical-shaped balloon including a distal portion and a proximal portion. The proximal portion is coupled to the distal end of the elongate shaft. The proximal portion has one or more reinforcement features including a layer of material coupled to the asymmetrical-shaped balloon and forming an outer contour at the proximal portion of the asymmetrical-shaped balloon that is asymmetrical to an outer contour of the distal portion of the asymmetrical-shaped balloon.
