Abstract
A medical device comprises an inner tube and an outer tube disposed about at least a portion of the inner tube. A balloon extends from the distal end of the outer tube. Within the balloon is a first expandable diaphragm, one end of which is attached to the inner tube. The first expandable diaphragm is covered by a retractable sheath disposed about the inner tube. Upon retraction of the retractable sheath, the diaphragm expands to sealingly contact the interior of the balloon in a first contact region and form at least a first compartment and a second compartment in the balloon.
