1. A balloon catheter comprising:
- a flexible catheter body portion extending longitudinally from a region remaining outside the body to an end region positioned inside the body,a spanning portion extending through said flexible body portion from the region remaining outside the body beyond the end region,a sliding region in sliding telescoping relationship with said spanning region between a retracted condition and an extended condition, andan inflatable balloon having a proximal and distal end portion, at least one end portion being attached to the sliding region.

Abstract
A medical balloon is collapsed to a small profile during deflation by preventing tension in the catheter or balloon which might otherwise direct the balloon into a larger diameter collapsed profile, making it difficult to remove the catheter from the body. Tension may be avoided by arranging at least one end of the balloon to slide with respect to the catheter body. The invention is particularly applicable to a relatively stiff, inelastic balloon that is preformed into a geometric cross-sectional shape with corners, such as a square balloon, for encouraging a particular collapsed configuration, e.g., three or more folded lobes.
