Claim 0:
1. A method for performing transseptal extracorporeal membrane oxygenation (ECMO) on a patient, the method comprising:
advancing a first inner catheter that is distally tapered and a second inner catheter through a transseptal puncture, wherein the second inner catheter is coaxial with and surrounds the first inner catheter and an outer surface of the second inner catheter is flush with an outer surface of the first inner catheter;
deflecting the first inner catheter within the left atrium so that a distal tip of the first inner catheter is disposed substantially toward a mitral valve;
advancing the first inner catheter and the second inner catheter through the mitral valve;
deflecting the distal tip of the first inner catheter toward an aortic valve;
advancing the first inner catheter and the second inner catheter through the aortic valve so that a distal end of the second inner catheter is in an ascending aorta;
withdrawing the first inner catheter; and
receiving, from the patient, oxygen-poor blood through an outer catheter and returning oxygenated blood through the second inner catheter to the ascending aortic arch.
