Abstract: In various examples, a method of making a guidewire is described. The method includes placing a polymer jacket over a core wire. The core wire includes a first portion having a first profile and a second portion having a second profile. The first profile is smaller than the second profile. Heat is applied to the polymer jacket and the core wire to reflow the polymer jacket and fuse the polymer jacket to the core wire, wherein the polymer jacket forms a layer of substantially uniform thickness along a length of the core wire. In some examples, a guidewire made using the method is also described.
