1. A method for introducing an interventional device into an artery, the method comprising:
introducing an arterial access sheath and an elongated first dilator into the artery via an access site while the first dilator is positioned within an internal delivery lumen of the arterial access sheath, and wherein the first dilator has a tapered distal tip and a first internal guidewire lumen, wherein at least a portion of the first dilator has a first bending stiffness;
removing the first dilator from the arterial access sheath; and
introducing an elongated second dilator into the internal delivery lumen while the sheath body is positioned within the artery, the second dilator having a tapered distal tip and a second internal guidewire lumen, wherein the second dilator has a distal region having a second bending stiffness different than the first bending stiffness of the first dilator.
