Device Story
Praxiject™ SP 0.9% NaCl is a single-use, prefilled plastic piston syringe containing 10mL of 0.9% Sodium Chloride Injection, USP. It features a Luer lock connection and a non-vented female Luer slip tip cap. The device is terminally sterilized by gamma irradiation and packaged in a flow-wrapped pouch serving as a dust cover. It is intended for use by healthcare professionals to flush vascular access devices. The device maintains a sterile fluid path only and is explicitly labeled for non-sterile field use. By providing a prefilled, ready-to-use saline solution, it simplifies flushing procedures, reduces preparation time, and minimizes the risk of contamination associated with manual syringe filling, thereby supporting maintenance of vascular access device patency.
Clinical Evidence
No clinical data. Substantial equivalence is supported by non-clinical bench testing, including USP chemical/physical analysis, sterility validation (ISO 11137), container closure integrity, and biological safety evaluation (ISO 10993 series including cytotoxicity, sensitization, irritation, hemolysis, and systemic toxicity).
Technological Characteristics
Prefilled plastic piston syringe (polypropylene barrel/plunger, bromobutyl rubber piston). Tip cap: polypropylene and thermoplastic elastomer. Luer lock connection. Terminally sterilized by gamma radiation (10-6 SAL). Single-use. Complies with ISO 7886-1, ISO 80369-7, ISO 11607, and USP standards for saline injection.
Indications for Use
Indicated for flushing vascular access devices. Not for use on a sterile field.
Regulatory Classification
Identification
An intravascular catheter is a device that consists of a slender tube and any necessary connecting fittings and that is inserted into the patient's vascular system for short term use (less than 30 days) to sample blood, monitor blood pressure, or administer fluids intravenously. The device may be constructed of metal, rubber, plastic, or a combination of these materials.

Dear Faiza Benazza:
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.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device"

## Device Description
The Praxiject™ SP 0.9% NaCl prefilled syringe is a single use plastic piston syringe with a Luer lock connection fitting, prefilled to labeled volume of 10mL with 0.9% Sodium Chloride Injection, USP, with no preservatives (normal saline), and capped with a plastic tip cap. The Praxiject™ SP 0.9% NaCl prefilled syringe is designed to maintain a sterile fluid path only and is individually packaged in a clear flexible plastic film, flow-wrapped heatsealed pouch that functions only as a protective barrier (dust cover). The device is terminally sterilized by gamma irradiation.
## Intended Use / Indications for Use
For vascular access devices flushing only. Sterile fluid path only. Not for use on a sterile field.
## Comparison of Technological Characteristics
The Praxiject™ SP 0.9% NaCl prefilled syringe is similar to the predicate device in intended use, indications for use, fundamental technology, operating principles, and performance characteristics. Technological differences in tip cap design and in syringe form and packaging of the Praxiject™ SP 0.9% NaCl that is supplied with a sterile fluid path only have been addressed by labeling and conformity to consensus standards. A side-by-side comparison of key device characteristics is presented in the following table:
