Abstract
A non-distensible balloon is adapted to be disposed circumferentially on a tube having an elongate axis and to be compressed against the tube to achieve a low profile. The balloon includes an end wall, a central wall, and a transition wall defined by a height transition region having a first axial length and defined by a thickness transition region having a second axial length less than the first axial length. An associated method includes the step of reducing the average volume of material per unit axial length in the transition wall of the balloon relative to the average volume of material per unit axial length in either the end wall or central wall of the balloon.
