ABSTRACT:
An endoscopic cardioplegic infusion cannula and its method of use is provided for occluding the ascending aorta and infusing cardioplegic fluid into the coronary arteries. A cannula is inserted suprasternally and the distal end of the cannula is inserted into the ascending aorta. An occlusion balloon on the distal end of the cannula is inflated and occludes the ascending aorta. Cardioplegic fluid is infused through the cannula proximal to the occlusion balloon and perfused into the coronary arteries. In order to effect a better seal where the distal end of the cannula is inserted into the ascending aorta, an outer sheath having a flange is advanced over the cannula into contact with the ascending aorta to compress a portion of the ascending aorta between the flange and the occlusion balloon. Cardiopulmonary bypass is effected in a known manner to supply the patient with oxygenated blood. The cannula and its method of use can be used in a closed or open chest procedure. Sternal lifting is used in conjunction with the present invention to create a greater working space over the heart.
