Abstract
The invention provides a balloon of non-elastomeric material which is spirally wrapped onto the main body of the catheter. The catheter is inserted in this condition and on inflation, the balloon aligns itself with the axis of the main body causing the body within the balloon to twist and store energy which is available for collapsing the balloon after use.
