An intravascular catheter may include a distal end for insertion and a proximal end. The distal end for insertion may terminate with a tip. It may define at least two openings of which one is proximal most in the distal end. The distal tip may include a first radiopaque marker that is discretely positioned at the proximal most opening and radiographically distinguishes the proximal most opening from the rest of the distal end. The distal tip may also include a second radiopaque marker that marks the tip.
