A balloon folding device (50) comprises a first die (52) having an extern al contacting surface (62) and a second die (54) having a cavity. A portion of the cavity comprises a contacting surface (64) shaped complimentary to th e external contacting surface of the first die. The second die is movable wi th respect to the first die. A balloon catheter (10) having a primary balloo n (20) and a secondary balloon (30) is oriented with the secondary balloon l ocated between the first die and the second die. The secondary balloon is fo lded by moving the second die toward the first die until the contacting surf aces of the dies contact, fold and deflate the secondary balloon. In some em bodiments, the dies are moved until at least a portion of the external conta cting surface of the first die is oriented within the cavity of the second d ie.
