Image Number 4 for United States Patent #5195990.

The coronary catheter of the present invention has an elongated tubular member or shaft, with a proximal end portion and the distal end portion. The distal end portion terminates in a tip end portion. In accordance with the present invention, the distal end portion of the catheter is curved in three dimensions and cooperative with the shape of the human aortic arch so as to automatically place the tip end of the catheter into proximity with the right coronary ostium as the distal end portion passes over the aortic arch and into the ascending aorta.
