Abstract
A coronary catheter has a transverse loop at the distal end of the catheter with two spaced, outwardly directed groups of openings centered to align with blood flow to respective coronary ostia when the catheter is in a maximum radius of curvature in the aorta. Each group of openings is spaced over a region of the outer peripheral wall of the loop so as to direct a fan-like pattern of contrast medium toward the aorta wall at the situs of the corresponding coronary ostium or directly upstream therefrom.
