Abstract
The balloon of an angioplasty balloon catheter is prepared for insertion through a patient's cardiovascular system by a series of steps to create three or more folded wings or flaps. The wings are wrapped circumferentially to provide a minimized outer diameter when the balloon is in its deflated state.
