摘要： A balloon catheter, for use with an introducer, includes an outer catheter, a telescopically disposed resilient inner catheter and a high-aspect, distal, inflatable balloon having one end of the balloon coupled to the inner catheter and an opposing end of the balloon coupled to the outer catheter. The balloon is joined at its corresponding ends to the corresponding inner and outer catheters, so that the balloon, when inflated, buckles and twists the inner catheter inside the outer catheter. This creates forces which automatically return the balloon to the wrapped configuration when deflated. The balloon diameter to length aspect ratio is equal to or greater than 1. The balloon is wrapped around the self adjusting inner catheter extended from the outer catheter when the balloon is deflated so that the outer and inner catheters with the deflated balloon fit and are disposable through the introducer.
