摘要: A catheter system and method for achieving total cardiopul-monary bypass during heart surgery. The venous perfusion has first second balloons occluding the inferior superior vena cava thereby precluding blood flow into right atrium. An arterial is inserted advanced positioned in ascending aorta cephalid of junction conorary ar-teries with aortic root. flexible cannula mounted an sliding relationship carries inflatable balloon adjacent its distal end to provide occlusion aorta. a lumen venting orifice communicating defining single path passage cardioplegia solution arrest or evacuation from third extends axially through communicates multiplicity openings tip suctioning left ventricle. cavity extending therethrough that opening at permit delivered by cardiopulmonary pump circulation. Both catheters have plurality ra-dially oppositely spaced steering lumens cables fixed ends achieve omnidirectional articulation.
