Three port manifold is used for percutaneous interventions. One port is connected by a drip set to the bottle delivering iodinated contrast dye. Second port is connected to the bottle delivering saline flush. Third port is connected to the pressure monitoring system through a pressure line extension. The dye injection syringe is connected to the proximal end of the manifold. Distal end is connected through an extension tubing to the valved connector at the proximal end of the catheter. Two port manifold can be used for coronary angiography. There is a rotating adaptor at the distal ends of the manifolds for facilitating rotation of the catheter within the aorta for engaging the vessel ostia.
Three port manifold connected to valved connector with extension tube attached. PTCA guide wire introducer has been inserted into the valved connector. The distal end of the connector will be attached proximal end of the guide catheter.
