Abstract
The present invention provides an aortic catheter having an upstream occlusion member positioned in the ascending aorta between the coronary arteries and the brachiocephalic artery and a downstream anchoring member positioned in the descending aorta, downstream of the aortic arch. The upstream occlusion member is in the form of a narrow, disk-shaped inflatable balloon. The downstream anchoring member may be a larger inflatable balloon or other anchoring structure that provides sufficient friction to prevent migration of the balloon catheter in the upstream or downstream direction. In addition, an arch perfusion lumen, a corporeal perfusion lumen and a cardioplegia lumen are provided for performing selective perfusion and cardioplegic arrest.
