Needle tip blunting using a length of a guidewire

Abstract

Guidewires include a distal section, a proximal section and a middle section disposed between the distal section and the proximal section, wherein the middle section has a flexural stiffness that is greater than a flexural stiffness of both of the distal section and the proximal section. The distal section is configured for insertion into a vasculature of a patient. A diameter of the middle section may be greater than a diameter of the distal section. The guidewires may include a tapered distal transition portion disposed between the distal section and the middle section and a solid core wire extending a length of the guidewires, the solid core wire including a first diameter extending along the distal section, a second diameter extending along the proximal section, and a third diameter extending along the middle section, wherein the third diameter is greater than the first diameter and second diameter.
