1. A method of stabilizing a catheter during transseptal access of a left atrium of a heart of a patient the method comprising the steps of:
delivering a delivery device through a vascular system of the patient to position the delivery device within a septal wall, the delivery device including:
a catheter including a plurality of lumens; and
a first stabilizer positioned within a first lumen of the plurality of lumens of the catheter during delivery, the first stabilizer including a first anchor secured to a first shaft, the first anchor having a delivery position during delivery, wherein the first anchor has a first diameter in the delivery position;
deploying the first stabilizer from the catheter to a deployed position such that the first anchor engages a first pulmonary vein, wherein the first anchor has a second diameter in the deployed position, the second diameter being greater than the first diameter; and
advancing a prosthesis through a second lumen of the plurality of lumens of the catheter and into the left atrium.
