Patients undergoing neurointerventional procedures with excessively tortuous vascular anatomy often have limited treatment options. The ability to pass and maintain the stability of micro-guidewires, catheters, and interventional devices is often a product of guide catheter steadiness. A companion wire passed through the lumen of the guide catheter to increase the guide catheter's stiffness can overcome the challenges associated with tortuous anatomy; this companion wire is referred to as a "buddy" wire. We demonstrate the technical success of this system by presenting a patient whose endovascular treatment would have otherwise been impossible without a "buddy" wire.
