Intended Use

The contrast delivery system REMPRESS is an intravascular injection system intended for the administration of contrast media or normal saline used in conjunction with angiographic imaging procedures.

Device Story

REMPRESS is an intravascular contrast delivery system used in angiographic suites. It consists of a Console, Powerhead, and Main Control Unit. The operator programs injection parameters (volume, flow rate, pressure) via a touchscreen graphical user interface on the Console. The Main Control Unit processes these inputs and commands the Powerhead. The Powerhead utilizes a screw-driven ram to apply force to a syringe plunger, expelling contrast media or saline into the patient's vascular system. A remote handswitch allows the operator to start or stop injections. The system provides real-time feedback on injection status and results. It includes safety mechanisms, such as electrical stops and a mechanical backup stopper, to prevent delivery if parameters exceed specified limits. The device benefits patients by enabling controlled, precise delivery of contrast agents during diagnostic or interventional imaging procedures.

Clinical Evidence

Bench testing only. Performance testing verified accuracy of delivered flow rate, volume, pressure, and manual control speeds against specified parameters. Testing confirmed the system successfully delivered volumes within allowable specifications and that pressure monitoring and safety stop mechanisms functioned correctly to prevent out-of-specification injections.

Technological Characteristics

System components: Console (touchscreen GUI), Powerhead (screw-driven ram), Main Control Unit. Materials: Plastics and metals. Energy: 24V DC (via remote AC/DC converter). Connectivity: Wired communications link between units. Safety: Electrical stop and mechanical backup stopper. Syringe capacity: 150ml. Flow rate: 0.1-25ml/sec. Pressure limit: 50-1200 PSI.

Indications for Use

Indicated for humans undergoing angiographic imaging procedures requiring the intravascular administration of contrast media or normal saline.

Regulatory Classification

Special Controls

*Classification.* Class II (special controls). The device, when it is a non-patient contacting balloon inflation syringe intended only to inflate/deflate balloon catheters and monitor pressure within the balloon, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 870.9.

POWERHEAD: The Powerhead provides a means for accepting and identifying a given syringe and then applying a force to the plunger of the syringe via its screw driven ram which will eject the contrast or normal saline from the barrel of the syringe. The Powerhead is in constant communications with the Main Control Unit for determining injection protocol and to monitor all Powerhead functions and injection sequences. The injection information is communicated to the user Console to provide immediate feedback of injection operation.

CONSOLE: The Console is the main user interface for the REMPRESS. It provides a color graphical user interface with an overlying touchscreen for easy injection monitoring and injection setup. At the completion of an injection the injection results are clearly displayed to the user. The Console provides a connection for a remote Handswitch that can be used to start or stop an injection. The Console resides normally in the angiographic suite and is typically located near the patient.

MAIN CONTROL UNIT: The Main Control Unit is the interface between the Console and the Powerhead. The Main Control Unit receives the user input data from the Console and converts.to the necessary control information then relays to the Powerhead. The Main Control unit also provides the power necessary to operate the Powerhead. The Main Control Unit is located inside the angiographic suite and communicates with the Console via a communications link.

The system is designed to deliver a variety of injection protocols. The REMPRESS injection system is also provided with a variety of consumables products for connecting the syringes to the patient.

#### SUBSTANTIAL EQUIVALENCE

A comparison chart shown in Table 1 compares the technological characteristics of the REMPRESS contrast delivery system to the predicate devices the Liebel-Flarseim's Angiomat Illumena and Angiomat 6000. The REMPRESS is substantially equivalent to the predicate devices. The REMPRESS injector system safely and effectively injects contrast or saline solutions as desired by the user.
