Indications for Use
The NRFit® cap is a sterile, single-use device intended to provide positive closure to prevent fluid loss and contamination in Neuraxial devices CADD Cassettes or Syringes utilizing NRFit® connections. The NRFit® cap is intended to be used for less than 24 hours on any single application.
Device Story
NRFit® Caps are sterile, single-use polypropylene caps designed to provide positive closure for neuraxial devices, CADD cassettes, or syringes featuring ISO 80369-6 compliant connections. Available in male and female configurations, the caps prevent fluid loss and contamination during clinical use. Operated by hospital or clinical personnel in general hospital settings, the caps are applied manually to the neuraxial device port. The device functions as a mechanical seal; it does not involve electronic processing or automated decision-making. By maintaining a secure connection, the caps support aseptic technique and prevent leakage, benefiting patients by ensuring the integrity of neuraxial delivery systems during short-term applications (less than 24 hours).
Clinical Evidence
No clinical data. Substantial equivalence supported by bench testing, including ISO 80369-6/20 performance testing, biocompatibility (cytotoxicity, sensitization, irritation, hemolysis, systemic toxicity, pyrogenicity), and packaging integrity (ASTM F1886).
Technological Characteristics
Medical grade polypropylene with yellow colorant. ISO 80369-6 compliant male/female neuraxial lock connections. Externally communicating, tissue/bone/dentin contacting. Sterilized via Ethylene Oxide. Single-use. Packaging integrity tested per ASTM F1886:2013.
Indications for Use
Indicated for use as a sterile, single-use closure for neuraxial devices, CADD cassettes, or syringes with NRFit® connections to prevent fluid loss and contamination for durations under 24 hours.
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 David Meily:
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 statutes and regulations administered by other Federal agencies. You must comply with all the Act's
{1}------------------------------------------------
requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
