1. A medical device comprising:
- an inner tube having a proximal portion and a distal portion;
an outer tube disposed about at least a portion of the inner tube, the outer tube having a proximal portion and a distal portion;
a balloon disposed about the inner tube, the balloon having a proximal end and a distal end, the proximal end of the balloon extending from the distal end of the outer tube;
a first inflation lumen in fluid communication with the balloon;
at least one first expandable diaphragm having a first end and a second end, the first end attached to the inner tube, the at least one first expandable diaphragm interior to the balloon;
a retractable sheath disposed inside of the balloon about the inner tube, the retractable sheath retractable from a first position in which it is disposed about at least a portion of the at least one first expandable diaphragm to a second position in which the retractable sheath is axially displaced from the at least one first expandable diaphragm.

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.

15. A medical device comprising:
-
a catheter tube;
a plurality of balloon elements disposed about the catheter tube;
an inflation lumen having a plurality of inflation ports therein, each balloon element disposed about at least one inflation port;
a movable sheath disposed about the inflation lumen, the movable sheath having a plurality of openings therein, the movable sheath movable such that each balloon element may be placed in fluid communication with the inflation lumen by moving the movable sheath to align an opening in the movable sheath with the inflation port about which the balloon element is disposed. - View Dependent Claims (16, 17, 18, 19, 20, 21)
