Abstract
Catheters with at least two curved portions near their distal ends are provided. The lengths and/or curvatures of the curved portions are selected so that a catheter can be advanced through a brachiocephalic or left subclavian artery (BCA or LSC) to access the ascending or descending aorta (AA or DA), withdrawn therefrom, and simply rotated to access the AA or DA. Hence, the catheters provide access to both the AA and DA through the BCA or LSC without any need to withdraw the catheter from the BCA or LSC, e.g., so a second catheter can be exchanged for it. The catheter can further be advanced through the DA into the abdominal aorta and rotated to access branch arteries including the vessels of the lower extremities. The catheters are usable for flush aortography, arteriography, and intravascular pressure measurements, and can be introduced to the BCA or LSC via radial artery access.
