The balloons being characterized as a relatively short inner tube which is inflated with high pressure and a longer outer tube which is inflated with low pressure. The balloons have independent inflation lumens which extend toward the proximal end of the inner tube.

A retractable outer sheath is further disposed about the medical device mounting region and is operatively connected near the proximal end of the catheter.
