MEDRAD® Centargo CT Injection System is an automated contrast injection system that is indicated for the controlled, automatic administration, on the venous side, of ULTRAVIST® (Iopromide), ISOVUE® (Iopamidol), OPTIRAY® (loversol), or OMNIPAQUE™ (lohexol) contrast media as supplied in an approved Imaging Bulk Package (IBP) presentation and 0.9% Sodium Chloride Injection USP (saline) to human subjects undergoing examinations in computed tomography (CT). The system is to be used by and under quasi-continuous supervision of trained healthcare professionals in an appropriate licensed healthcare facility, in a room designated for radiological procedures that involve intravascular administration of contrast agent. The Day Set is used for a maximum time of twenty-four (24) hours, or for a maximum of 25 bottles of contrast media, whichever comes first. The Patient Line must be discarded after each patient procedure. The Replacement Spike is for single-container use only and must be discarded with the fluid container. Contrast media containers are to be discarded after their respective use times have expired or the Day Set use life has expired, whichever occurs first. Saline should only be used to deliver multiple single doses to multiple patients when used with the MEDRAD® Centargo CT Injection System and the provided Saline Tag. Once the port of the saline container is punctured, it should not be removed from the work area during the entire period of use. Saline containers are to be discarded with the Day Set.

The MEDRAD® Centargo CT Injection System (Centargo) is an automated contrast injection system intended to be used to inject intravenous contrast media and saline into humans for diagnostic studies in CT applications. Centargo is intended for use with the following approved contrast media in an Imaging Bulk Package (IBP): - . ULTRAVIST® (Iopromide) NDA 021425/S-034 - . ISOVUE® (Iopamidol) NDA 020327/S-023 - . OPTIRAY® (loversol) IBP NDA 020923/S-026 - . OMNIPAQUE™ (lohexol) NDA 020608/S-045 Centargo is based on well-established technologies for injection, using a piston-based electromechanical device. The system is designed to protect the patient against air injection by incorporating multiple sensors to detect air within the fluid pathway. The system is comprised of two main modules: - Scan Room Unit – responsible for handling the contrast/saline and delivering injections - . Control Room Unit - controls, monitors, and communicates with the Scan Room Unit through wired or wireless connection The Scan Room Unit is located within the scan room whereas the Control Room Unit is not. When communicating via wired or wireless connection, the Control Room Unit can remotely control the Scan Room Unit and initiate and execute injections. However, the Scan Room Unit can operate independently without the use of the Control Room Unit via the Scan Room Unit's graphical user interface (GUI). The Scan Room Unit is available in two different configurations: - . Pedestal with battery and AC power - Overhead mount with AC power only ● The fluids are delivered from a multi-patient disposable set (Day Set) through a single use patient line (Patient Line). The Day Set is labeled for 24 hours or for a maximum of 25 bottles of contrast media, whichever comes first. Fluid source spikes (Replacement Spike) are for single container use.

The OptiOne Single-Head Contrast Delivery System is a contrast delivery system and is designed to inject radiopaque contrast media into a patient's vascular system to obtain diagnostic images with computed tomography (i.e. "CT") equipment.

The OptiOne Single-Head Contrast Delivery System (OptiOne) is intended to inject radiopaque contrast media into a patient's vascular system to obtain diagnostic images when used in conjunction with computed tomography equipment. Each injection is accomplished with a motor-driven syringe mechanism with microprocessor control of the flow rate, volume, pressure and timing. The OptiOne consists of the following key components: a Powerhead, a Console, and a Power Supply. The Power Supply delivers power to the Powerhead and Console. The Console provides remote control and programmability of the injection through a touch screen display system. The Powerhead contains the components to perform the actual injection such as motor control circuits, ball screw and syringe push ram.

The contrast delivery system Sonic Shot GX is an intravascular injection system intended for the administration of MRI contrast media and normal saline solution used in conjunction with magnetic resonance imaging (MRI).

The contrast delivery system Sonic Shot GX is an intravascular injection system intended for the administration of MRI contrast media and saline used in conjunction with MRI. The main components of the Sonic Shot GX are the Console, Powerhead and Main Control Unit. The Console resides in the control room or the MR suite, while the Main Unit and Powerhead reside in the scanning room alongside the MR scanning device and the patient. The parameters of the injection, such as volume, flow rate and pressure are programmed by the operator via the graphical user interface with touchscreen input. The Console is powered via 24 volts DC which is derived from a remote AC to DC converter (similar to that used with laptop computers) and communicates with Main Control Unit via a fiber-optic interface. The communication link is used to communicate the user set injection parameters to the Main Control and Powerhead located in the MR suite. After the injection protocol has been set, the Powerhead performs the injection by driving one or two lead screw rams. The rams push the syringe which expels fluid from the barrel of the syringe.
