1. A flexible tip dilator made of at least a first material and a second material, the flexible tip dilator comprising:
a hollow elongated tubular member comprising a proximal region and a tapered distal region, the tapered distal region being of continuously decreasing diameter and defining an exterior surface of the flexible tip dilator, the tapered distal region comprising a first region, a second region distal to the first region, and a third region distal to the second region,
wherein the first region of the tapered distal region is made of at least the first material but not the second material,
wherein the second region of the tapered distal region comprises the first material and the second material overlapping one another, the second material being different from and more flexible relative to the first material, and
wherein the third region of the tapered distal region is made of at least the second material but not the first material,
wherein the first material in at least the first region of the tapered distal region forms a first portion of the exterior surface of the flexible tip dilator,
wherein the second material in at least the third region of the tapered distal region forms a second portion of the exterior surface of the flexible tip dilator.
