Intended Use

The B. Braun Omnifix Syringe NRFit is intended to inject fluid into, or withdraw fluids from, the body.

Device Story

Sterile, single-use piston syringe; 1mL, 3mL, 10mL, 20mL capacities; lock and slip configurations. Features ISO 80369-6 compliant NRFit small-bore connector to prevent misconnections with non-neuraxial devices. Plunger rod colored yellow for visual identification of neuraxial compatibility. Operated manually by healthcare professionals in clinical settings; plunger rod depressed to inject or pulled to aspirate fluids. Used for neuraxial applications involving potential indirect contact with cerebral spinal fluid. Design modification from standard Luer (ISO 594) to NRFit (ISO 80369-6) limits device to neuraxial use. Benefits include reduced risk of medication errors via misconnection.

Clinical Evidence

Bench testing only. No clinical data. Performance validated via ISO 80369-6 functional tests (dimensional, leakage, pressure decay, stress cracking, separation force, unscrewing torque, overriding resistance), biocompatibility (cytotoxicity, sensitization, systemic toxicity, genotoxicity, pyrogenicity, hemolysis), and neurotoxicity assessment. Packaging integrity verified via ASTM F2096 and ASTM F88/F88M.

Technological Characteristics

Materials: Polypropylene (barrel), Polyisoprene (stopper), Silicone (lubricant/stopper). ISO 80369-6 compliant NRFit small-bore connector. Manual operation. Sterilization: Ethylene Oxide (SAL 10^-6). Shelf life: 5 years. Complies with ISO 7886-1 (hypodermic syringe function) and ISO 10993-1 (biocompatibility).

Indications for Use

Indicated for neuraxial use for aspiration/injection of fluids by healthcare professionals in healthcare facilities.

Regulatory Classification

Identification

A piston syringe is a device intended for medical purposes that consists of a calibrated hollow barrel and a movable plunger. At one end of the barrel there is a male connector (nozzle) for fitting the female connector (hub) of a hypodermic single lumen needle. The device is used to inject fluids into, or withdraw fluids from, the body.

## Dear Kimberly Smith:

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 (the 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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

## Reason for Submission

The purpose of this submission is for the modification of the current B. Braun Medical Inc. Single Use, Piston Syringe (previously cleared under K071459) from the current Luer connections per ISO 594-1 and ISO 594-2 to the new ISO 80369-6 connectors referred to as NRFit. The new syringes with NRFit connectors will be referred to as Omnifix Syringe NRFit and will be supplied in luer slip and luer lock configurations. B. Braun Medical Inc. will continue to market the current B. Braun Medical Inc. Single Use, Piston Syringes with Luer connections for general purpose use, while the new B. Braun Medical Inc. Omnifix Syringe NRFit will be indicated for neuraxial use per ISO 80369-6.

## Device Description

B. Braun Medical Inc. Omnifix Syringe NRFit configurations are sterile, single use syringes with ISO 80369-6 NRFit compliant fittings. They are available in 1mL, 3mL, 10mL, and 20mL lock and slip configurations. The NRFit tips allow for connections of neuraxial specific applications while reducing the likelihood of misconnections to non-neuraxial devices. The syringe assembly consists of a barrel with a printed graduated scale in milliliters (mL), a stopper and a plunger rod. The plunger rod is yellow to designate a device intended to only connect to ISO 80369-6 compatible devices such as spinal or epidural needles. The plunger rod is pulled back to aspirate fluids or depressed to inject or expel fluids.

### Indications for Use

The B. Braun Omnifix Syringe NRFit is intended for neuraxial use for aspiration/injection of fluids used by healthcare professionals in healthcare facilities.

### Intended Use

The B. Braun Omnifix Syringe NRFit is intended to inject fluid into, or withdraw fluids from, the body.

### Technological Characteristics

The B. Braun Medical Inc. Omnifix Syringe NRFit configurations are equivalent to that of the predicate B. Braun Medical Inc. Omnifix Syringe in intended use, materials and performance characteristics.

The difference between the proposed and predicate B. Braun Medical Inc. Omnifix Syringe is the modification of the tip of the current B. Braun Medical Inc. Single Use, Piston Syringe from the current Luer connections per ISO 594-1 and ISO 594-2 to the new ISO 80369-6 connectors referred to as NRFit. This modification therefore revises the Indications for Use for a neuraxial use application but does not modify the intended use. These differences do not impact the statement of substantial equivalence.

{6}------------------------------------------------

The intended use of the proposed and predicate devices are the same in that both are intended for use by healthcare professionals for aspiration/injection of fluids. However, due to the ISO 80369-6 connector, the Omnifix Syringe NRFit configurations are limited to neuraxial applications. As such, the neuraxial indication, is a subset of the predicate indications for use, which is for general use. Therefore, the above difference in indications for use is not critical to the intended use as the intended use remains for aspiration of fluids. It further does not affect the safety and effectiveness of the device when used as labeled as demonstrated through functional testing. ISO 10993-1 biocompatibility testing, a neurotoxicological assessment, and ISO 80369-6 functional performance testing were conducted to address the changes in indications for neuraxial use and tip design.

## Nonclinical Performance Tests

Bench testing performed on the proposed devices supports substantial equivalence. No clinical testing was performed as this device does not require clinical studies to demonstrate substantial equivalence with the predicate device. The following ISO 80369-6 testing has been completed for the proposed device.

- · Dimensional Requirements
- · Fluid leakage requirement
- · Leakage by pressure decay
- · Subatmospheric pressure air leakage
- · Stress cracking
- · Resistance to separation from axial load
- · Resistance to separation from unscrewing
- · Resistance to overriding

{7}------------------------------------------------

A biocompatibility evaluation was conducted on the subject device per ISO 10993-1:2018. The contact classification is external communicating, indirect contact with blood and tissue with a prolonged use. Based on the evaluation, the following biological tests were conducted:

- · Cytotoxicity
- · Intracutaneous reactivity
- · Sensitization
- · Acute systemic toxicity
- · Subacute/subchronic systemic toxicity
- · Genotoxicity
- · Material-mediated pyrogenicity
- Hemolysis

Additionally, the following tests were performed:

- · Particulate Matter per USP <788>
- · Neurotoxicity assessment

Packaging: Per ASTM F2096:2011 · Bubble Leak Testing Per ASTM F88/F88M:2015 · Seal Strength Testing

## Summary of Substantial Equivalence

The B. Braun Medical Inc. Omnifix Syringe NRFit configuration is substantially equivalent to the predicate device in intended use, principles of operation, technology, design, materials and performance and are as safe and effective as the predicate devices.
