Abstract: A balloon dilatation catheter has a flexible, hollow inner shaft (10) and an outer, braided shaft (20) with a balloon (1) that is inflatable by fluid introduced between the outer and inner shaft. The inner shaft (10) is fixed relative to the outer shaft (20) at both ends such that, when the ballon (1) is inflated, the outer shaft shortens and the excess length of the inner shaft is accommodated by the inner shaft bending into a coil (100) within the balloon.
