A method and apparatus for selectively entering and visualizing normal and geriatrically displaced aortic branch arteries comprising a catheter shaft having an outer wall defining a central lumen, the outer wall comprising a first portion having a substantially linear shape, a second portion extending at an angle in a curved manner from the first portion and suitable for providing ease of passage for the catheter from a patient's aorta into a branch artery and optionally having a plurality of apertures extending through the outer wall into the central lumen, and a third portion extending at an out of plane angle and in a curved manner from the second portion and suitable for providing hooked engagement of an aortic branch artery; and a soft deformable catheter tip having a distal central aperture in flow through communication with the central lumen. |
