?:definition
  • Angiographic vascular catheters designed to inject contrast media in branch vessels originating from the aorta. Typically, these catheters have three curves: a primary curve convex in one direction, a secondary curve convex in the opposite direction, and a short tip angled in the same direction as the primary curve. This configuration is intended to facilitate positioning the catheter into a branch vessel originating from the aorta (e.g., superior mesenteric artery, renal artery) at different angles. These catheters must have very good torque control and memory to facilitate their movement in the aorta. Visceral angiographic vascular catheters are used in diagnosis of the abdominal organs and also in more detailed examinations or treatments (e.g., chemotherapy) by selective introduction into secondary or tertiary branches of the visceral vessels.
