Adjustable balloon catheter including an inner tubular member that has an inflation lumen. An expandable member is coupled to the distal end portion of the inner tubular member and has an inner chamber in fluid communication with the inflation lumen. The expandable member is transitionable between a deflated and an inflated configuration. The expandable member defines has a non-cylindrical shape including a first section having a first diameter in the inflated configuration and a second section having a second diameter when in the inflated configuration. The first diameter is different than the second diameter. An outer tubular member is movable relative to the inner tubular member. The outer tubular member is moveable between an extended position disposed over the expandable member and a fully retracted position proximal to the extended position. The outer tubular member is selectively positioned between the extended position and the fully retracted position.
