The outer wall being formed from a stretchable elastic material and being stretchable by pressure within the inner hollow between a collapsed state and an expanded state. The substantially continuous outer wall has a base portion for coupling with shaft, an intermediate portion adjacent to the base portion and an end portion at a distal end of the balloon and adjacent to the intermediate portion. The base portion has a first primary wall thickness, the intermediate portion has a second primary wall thickness, and the end portion has a third primary wall thickness.
