Original Abstract Submitted

A catheter may be provided. The catheter may include an expandable occlusion element coupled to an external surface of a tubular body at a proximal end of the expandable occlusion element and a distal end of the expandable occlusion element. An inner surface of the expandable occlusion element may define a volume of space between the inner surface of the expandable occlusion element and an external surface of the tubular body. The catheter may include a plurality of lumens. A first lumen may be configured to allow a first fluid to be introduced and/or removed from the volume of space defined by the inner surface of the expandable occlusion element. A second lumen may be configured to receive a pressure sensor or define a fluid-filled pressure transducer. A third lumen may be configured to allow a second fluid to be removed from the volume of space.
