Claim 10:
11. A method for performing transseptal extracorporeal membrane oxygenation (ECMO) on a patient, the method comprising:
advancing a first catheter that includes an inner sheath and an outer sheath through a transseptal puncture, wherein the outer sheath is coaxial with and surrounds the inner sheath and an outer surface of the outer sheath is flush with an outer surface of the inner sheath;
advancing a second catheter into a large peripheral vein or an inferior vena cava;
deflecting the inner sheath within the left atrium so that a distal tip of the inner sheath is disposed substantially toward a mitral valve;
advancing the inner sheath through the mitral valve;
deflecting the distal tip of the inner sheath toward an aortic valve;
advancing the first catheter through the aortic valve and into an ascending aorta;
withdrawing the inner sheath from the first catheter; and
receiving, from the patient, oxygen-poor blood through the second catheter and returning oxygenated blood through the first catheter into the ascending aorta.
