Abstract
A balloon catheter is provided to minimize curving of the balloon when the balloon is expanded with an inflation media. The balloon catheter has an elastic inner shaft that stretches longitudinally as inflation pressure in the balloon is increased. The balloon catheter may also have an inner shaft with a portion that is corrugated to allow longitudinal stretching of the inner shaft.
