A method of manufacturing a catheter can include assembling an inner balloon within a separate outer balloon. The inner and outer balloons can each be open on opposing longitudinal ends and have a central radially expandable portion, and proximal and distal reduced diameter portions on opposite longitudinal end portions of the balloon. The method can further include bonding a portion of an inner surface of the outer balloon proximal reduced diameter portion to a portion of an outer surface of the inner balloon proximal reduced diameter portion and bonding a distal end portion of an elongate catheter shaft to a proximal portion of the bonded inner and outer balloons.
