Angiographic vascular catheters designed to inject a large bolus of contrast media into the aorta, minimizing trauma during injection. Typically, these catheters include a long, tapered pigtail configuration to reduce the flow of contrast medium from the end hole; they have several side holes near the tip for even dispersion of the contrast medium. Peripheral angiographic catheters are used to visualize the distal aorta, the iliac and femoral arteries, and other secondary vessels in studies of circulation in the lower limbs.
