Abstract
A balloon catheter having a safety feature for protecting a patient during a medical procedure in the event the inflated balloon ruptures during the procedure. The catheter contains an outer balloon attached to the distal end of an insertion tube and a second inner balloon totally enclosed within the outer balloon. A vacuum is drawn on the outer balloon to evacuate the interior of the balloon and the inner balloon is then inflated to a desired operating pressure. In the event the inner balloon ruptures while inflated, the inflation fluid is fully contained within the outer balloon as well as any inner balloon fragments that are released due to the rupture.
