ABSTRACT:
An x-ray contrast media catheter, for example a cardiac catheter, comprises a flexible tube defining a lumen and a plurality of side apertures in the tube for fluid flow therethrough. The side apertures are each defined by a tubular surface extending through the side wall from the lumen of the exterior, in which the tubular surface defines a longitudinal axis which forms a forward angle of about 30.degree. to 60.degree. to the longitudinal axis of the catheter. Also, the distal end preferably defines an open aperture which, in turn, is defined by a bevelled tip of the catheter distal end. This provides improvements in the fluid flow dynamics when x-ray contrast media is being administered to a heart chamber.
