The fibers of the first fiber layer run substantially parallel to one another and substantially parallel to the longitudinal axis. The fibers of the first fiber layer have a pattern of different lengths and are divisible into a first group and a second group based on length. Each fiber of the first group begins in the neck wall at one end of the balloon, extends continuously in the longitudinal direction and terminates in the neck wall at the opposite end of the balloon. Substantially all of the fibers of the first group have a generally uniform length. Each fiber of the second group begins in the cone wall at one end of the balloon, extends continuously in the longitudinal direction and terminates in the cone wall at the opposite end of the balloon. The length of the fibers of the second group varies progressively in accordance to their proximity to the fibers of the first group; the fibers of the second group closest to the fibers of the first group being longer than the fibers of the second group further from the fibers of the first group. The fiber of the second fiber layer winds circumferentially around the longitudinal axis of the balloon substantially over the entire length of the balloon including the neck walls, the cone walls and the barrel wall. | 2009-02-12 |
