Intended Use

Argon's Continuous Flush Device is intended for use in invasive physiological pressure measurements which require continuous regulated flow to maintain catheter patency.

Device Story

Argon Continuous Flush Device is an accessory for invasive physiological pressure monitoring systems; maintains catheter patency by providing slow, continuous saline flush. Device connects to IV administration set and pressurized saline bag (300 mmHg). Flow rate (3 ml/hr or 30 ml/hr) determined by laser-drilled orifice diameter. Features 'fast flush' mechanism (squeeze tabs or pull tab) for priming, bubble removal, and system integrity assessment. Used in clinical settings by healthcare professionals. Minimizes blood clot formation at catheter tip, ensuring monitoring integrity.

Clinical Evidence

Bench testing only. No clinical data provided.

Technological Characteristics

Materials: industry-standard plastics and silicone. Flow control: laser-drilled orifice (3 ml/hr or 30 ml/hr). Actuation: manual squeeze or pull-tab. Connectivity: integrates into IV administration sets for pressure monitoring. Sterilization: not specified.

Indications for Use

Indicated for use in invasive physiological pressure measurements requiring continuous regulated flow to maintain catheter patency in patients undergoing such monitoring.

Regulatory Classification

Identification

A continuous flush catheter is an attachment to a catheter-transducer system that permits continuous intravascular flushing at a slow infusion rate for the purpose of eliminating clotting, back-leakage, and waveform damping.

Predicate Devices

• Edwards Uniflow Flush Device (K792141)
• American Pharmaseal Blood Pressure Transducer (K832907)

## Predicate Device

Edwards Uniflow Flush Device and American Pharmaseal Blood Pressure Transducer including a continuous flush device are the predicate devices for the Argon Continuous Flush Device. The 510(k) for the original Edwards Uniflow Flush Device is K792141. filed by the Edwards Critical Care Division of Baxter Healthcare. K832907 was filed by American Pharmaseal, also a Baxter Edwards company, for a blood pressure transducer that included a continuous flush device. The flush device included as an integral part of the American Pharmaseal transducer is also sold individually by Edwards Lifesciences. This device was used for the bench testing.

#### Description of the Device

Invasive physiological pressure monitoring requires a number of components that include an IV administration set, a pressure transducer, a monitoring line and a catheter. Because of the potential for clot formation over the course of physiologic monitoring, a continuous flush device can be included in these systems for slow flush of the monitoring line. This minimizes the possibility that blood clots will form within the catheter and at the catheter tip. The Argon Continuous Flush Device is a slow flush device that is intended to be used with the components identified above for slow and continuous flushing of indwelling lines to minimize the formation of clots that would interfere with monitoring integrity.

The Argon Continuous Flush Device is manufactured in two distinct configurations, a 3 ml/hr flow rate device and a 30 ml/hour flow rate device. The design difference which results in continuous flow rates of 3 ml/hr and 30 ml/hr for each of the two models of devices is achieved by the diameter of a laser-drilled flow control orifice in each unit.

{1}------------------------------------------------

The orifice diameter is predefined for each version to correlate to the desired output flow rate. The two devices are distinguished from one another by the color of the flush device cap. The 3 ml/hr continuous flush device has a clear cap and the 30 ml/hr continuous flush device has a yellow cap.

Both devices are connected to an IV administration system including a pressurized bag of saline that typically is heparinized. Applied pressure from the bag (300 mmHg) initiates the flow through the IV administration set and the flush device. The slow flow prevents over-infusion, and minimizes clot formation. The "fast flush" feature of the device assists in priming and removing bubbles from the lines or catheters and supplying a fast flow of intravenous fluid to the patient to assess the integrity of the entire monitoring system. This feature is actuated by squeezing the tabs on either side of the device or by pulling up the pull tab on the top of the device.

## Intended Use of the Device

Argon's Continuous Flush Device is intended for use in invasive physiological pressure measurements which require continuous regulated flow to maintain catheter patency.

# Technological Characteristics Compared to Predicate Device

Both the Argon Continuous Flush Device and Edwards Uniflow Flush Device are manufactured using industry standard plastics and silicone. Specific material information for the Argon Continuous Flow Device is detailed in another section of the 510(k). Design characteristics of each device are very similar. Both Argon's and Edwards' device includes a squeeze actuator and a pull tab for fast flush. Configurations vary with female/male or glue sites to connect to a transducer or monitoring line. Each device has a specified orifice diameter that allows either a nominal 3 ml/hr or a nominal 30 ml/hr fluid flow.

## Performance Summary

Non-clinical performance data demonstrates that the Argon Continuous Flush Device performed in an equivalent manner to the predicate and is suitable for its intended use.

Dear Ms. Windham:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
