The device description and performance studies focus on the mechanical and material properties of a syringe, with no mention of AI or ML.
No.
The device is a syringe for administering substances, not an active therapeutic device itself.
Yes
The intended use explicitly states "for locating the epidural space," which indicates a diagnostic function.
No
The device description clearly states it is a physical syringe made of glass and metal, and the performance studies are focused on physical properties and standards for syringes and connectors. There is no mention of software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use describes the device being used for locating the epidural space and administering substances within the body (local and regional administration). This is an in vivo application.
- Device Description: The description details a syringe designed for delivering liquids, not for analyzing samples outside the body.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes, which are the hallmarks of an IVD.
The device is clearly intended for direct medical intervention on a patient, not for laboratory testing of biological samples.

Intended Use / Indications for Use
The Top NRFit Lock Tip and Slip Tip LOR Syringes and the Additive Slip Tip Syringe are intended to be used with the ISO 80369-6 NRFit neuraxial compliant epidural needles for locating the epidural space, for local administration, and regional administration excluding subarachnoid/spinal block.

Device Description
The TOP NRFit™ Tip Syringes are provided sterile. They are single use devices consisting of rigid USP 2 glass plungers and glass barrels with metal slip tips designed as the ISO 80369 - 6 compliant neuraxial connector which allows for connections of neuraxial specific applications while reducing the likelihood of misconnections to non-neuraxial devices. The syringe barrels are printed with graduated markings in cc (milliliters) indicating the volume of liquid inside the syringe barrel. The proposed models for the neuraxial devices are listed below in Table 1 and 1a, where Table 1a part numbers identify products which include a distributor logo on the syringe barrel.

Dear Jonathan Gilbert:
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. 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 located 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.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal

Discussion of differences in technological characteristics
Differences in materials between the subject device K182765 and primary predicate K170218 were addressed through biocompatibility testing per ISO 10993-1 Biological evaluation of medical devices.
Differences in syringe sizes and neuraxial tip between the subject device K182765 and K843414 were addressed through ISO 80369-6, ISO 80369-20 and ISO 7886-1 performance testing.
These differences do not raise different questions of safety and effectiveness.
The clinical technique, technical specifications, materials used, and sterility status (validation and sterility assurance level) are substantially equivalent to either K843414 or K170218. As stated above, the NRFit™ tip syringes provide connections of neuraxial specific applications while reducing the likelihood of misconnections to non-neuraxial devices.
Performance Testing:
The performance of the subject TOP NRFit™ Tip Syringes is demonstrated as tested per ISO 80369-6, Small bore connectors for liquids and gases in healthcare applications -Part 6: Connectors for neuraxial applications.
