1. An endovascular introducer assembly, the introducer assembly comprising:

  • a dilator tip formed of a flexible material having a distal end, a proximal end, and a natural unbiased condition;

    a lumen formed within and extending the length of the dilator tip between the distal and proximal ends; and

    a guide wire disposed in the lumen, the guide wire comprising,a distal region adjacent to the distal end,a proximal region adjacent to the proximal end, andan intermediate region disposed between the distal and proximal regions,wherein the dilator tip comprises,a first biased condition having a first biased radius of curvature when the dilator dip is disposed about the distal region of the guide wire;

    a second biased condition having a second biased radius of curvature when the dilator tip is disposed about the proximal region of the guide wire, anda third biased condition having a third biased radius of curvature when the dilator tip is disposed about the intermediate region of the guide wire, wherein the first biased radius of curvature is less than the third biased radius of curvature, the second biased radius of curvature is between the first and second biased radii of curvatures.
