Abstract:
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.

Claim (Index 9):
An angiographic catheter configured for injecting contrast solution into retrograde blood flow in a vessel of a patient, the angiographic catheter comprising:\n a catheter body having a proximal end portion, a distal end portion with a distal end, an exterior surface defining a circumference, and a fluid passageway extending from the proximal end portion toward the distal end portion; a luer fitting hub at the proximal end portion; a strain relief section adjacent to the luer fitting hub; a series of fluid outlet openings formed in the catheter body adjacent to the distal end portion thereof, the fluid outlet openings extending from the fluid passageway through the exterior surface to place the fluid passageway in fluid communication with an exterior of the catheter body; the fluid outlet openings extend along a length of the catheter body in a direction away from the distal end and the fluid outlet openings are spaced circumferentially around the circumference of the catheter body; and the fluid outlet openings have ejection axes that are angled in a direction toward the distal end whereby contrast solution is ejected through the fluid outlet openings at an acute angle.
