ABSTRACT:
A balloon dilatation catheter has a flexible, hollow inner shaft and an outer, braided shaft with a balloon that is inflatable by fluid introduced between the outer and inner shaft. The inner shaft is fixed relative to the outer shaft at both ends such that, when the balloon is inflated, the outer shaft shortens and the excess length of the inner shaft is accommodated by the inner shaft bending into a coil within the balloon.
