Claim 12:
13. A method comprising:
inflating an inflatable balloon of a balloon catheter through a flow path that traverses an elongated shaft of the balloon catheter, a central lumen of a central tube positioned within the inflatable balloon, inflation ports of the central tube, and an interior of the inflatable balloon;
structurally supporting the inflatable balloon along a longitudinal axis of the balloon catheter with the central tube, the central tube being aligned with the longitudinal axis so that at least a portion of the central tube is positioned within the inflatable balloon;
extending the inflatable balloon in length in relation to the longitudinal axis by allowing an elastic element coupled to the central tube and shaft to self-elongate thereby sliding the central tube longitudinally in relation to the shaft; and
contracting the inflatable balloon in length in relation to the longitudinal axis by retracting a puller-wire connected to the central tube and extending through the shaft thereby compressing the elastic element along the longitudinal axis and sliding the central tube longitudinally in relation to the shaft.
