Aortic catheter and methods for inducing cardioplegic arrest and for selective aortic perfusion

Year	Description
1998	Invention patented by John F. Bresnaham, John A. Macoviak, Wilfred J. Samson, Steve G. Baker, and Karl Van Dyk on December 3rd, 1998. 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 may be an inflatable balloon or a selectively deployable external catheter valve. 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.
