Abstract: A balloon catheter (10) may comprise a primary inflation balloon (20) and a secondary inflation balloon (30) located to one side of the primary inflation balloon. The secondary balloon comprises a first portion and a second portion, the first portion located closer to the primary balloon. The second portion has a greater size than the first portion, and a portion of the second portion extends outwardly beyond the first portion and overhangs the first portion. In some embodiments, a cross-sectional shape of the secondary balloon in an inflated state comprises a mushroom shape.
