摘要：
A catheter that is configured to achieve high velocity injections of contrast solution that will not readily wash out in retrograde blood flow. The distal end of the catheter can include a plurality of fluid outlet openings. The fluid outlet openings are spaced circumferentially around the circumference of the catheter and the fluid outlet openings have ejection axes that are angled in a direction toward the distal end so that a velocity component of the ejected contrast solution is against or opposite the retrograde blood flow.
