A new method of catheterizing the great vessels arising from the aortic arch.

A deflecting guidewire system allows rapid catheterization of the major vessels arising from the aortic arch with a 5.4 French catheter. Selective catheterization of the branches of these vessels is also possible. The system has been used to catheterize the brachial, costocervical, thyrocervical, vertebral, internal carotid and external carotid arteries via a femoral artery approach.
