1. A method of manufacturing a dilator for use with a delivery catheter, the method comprising:
forming the dilator to have a cylindrical base, a central guidewire lumen extending through the cylindrical base, and a tapered tip;
positioning a steering ring over a distal end portion of the cylindrical base, the steering ring having at least one steering cable coupled thereto;
after positioning the steering ring, forming an exterior jacket over the cylindrical base so that the exterior jacket has a proximal portion formed of a first material and a distal portion formed of a second material different than the first material, the proximal portion being stiffer than the distal portion.
