Internal thoractic artery catheter

A catheter for selectively entering and visualizing normal and geriatrically displaced branch vessels of the arch of the aorta and internal thoracic artery origins comprising:

• a catheter shaft having outer walls defining a central lumen, said outer walls comprising a first portion having a substantially linear shape in an X axis, a second portion extending at an angle toward a Y axis in a curved manner from said first portion and suitable for providing ease of passage for the catheter from a patient's aortic arch into one of the aortic arch branch vessels and a sub-branch of that vessel, and a third portion extending only toward a Z-axis at an out of plane angle relative to said first and second portions, into portion Z-axis orientation permitting hooked engagement of an internal thoracic artery origin.
