The device description and performance studies focus on mechanical principles and standard biocompatibility/performance testing, with no mention of AI/ML terms or data-driven performance metrics.
No.
The device is used for detecting loss of resistance to verify needle tip placement, which is a diagnostic or procedural aid, not a direct therapeutic intervention.
Yes
The device aids a clinician in verifying needle tip placement, which is a diagnostic function because it provides information about a physiological state or condition (the location of the needle).
No
The device description clearly describes a physical syringe with a spring-loaded piston, indicating it is a hardware device, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to aid a clinician in verifying needle tip placement in the epidural space by detecting a loss of resistance. This is a procedure performed directly on the patient's body, not on a sample taken from the body.
- Device Description: The device is a syringe designed to detect a physical change (loss of resistance) during a medical procedure. It does not analyze biological samples.
- Lack of IVD Characteristics: There is no mention of analyzing blood, urine, tissue, or any other biological sample. There is no mention of detecting diseases, conditions, or states of health based on the analysis of such samples.
IVD devices are specifically designed to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.

Device Description
The EpiFaith is a loss of resistance syringe with spring loaded piston, which can provide a means for detecting entry into the epidural space. Based on the principle of LOR technique, the piston will simultaneously move forward when the pressure drop occurs due to the spring force. The moving of the piston can provide a visual signal to indicate the LOR as well as verify the needle tip placement in the epidural space. The EpiFaith syringe is compatible to a 16-18 gauge epidural needle with Luer or NRFit connector. The user can push the plunger to increase the pressure after the syringe is connected to an inserted needle. Then, the user can advance the needle until the visual signal occurring. Because the piston is spring loaded, the automatic ejection of the syringe will happen when the LOR occurring, resulting in the movement of the piston. There are two different models of EpiFaith Syringe. The proposed models are listed below. The only difference between two models is the type of the connector.

Dear Shao Wei Tseng:
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.

Non-Clinical Tests
We have conducted non-clinical testing based on its risk assessment utilizing Failure Mode Effect Analysis (FMEA). The following evaluations were conducted to validate the modifications made to the subject device:
- Risk assessment (ISO 14971: 2007)
- -Friction forces test and liquid leakage test (ISO 7886-1: 2017)
- -Biocompatibility Assessment per ISO 10993: In vitro cytotoxicity, Skin sensitization, Intracutaneous irritation, Acute systemic toxicity, Pyrogen test, Limulus amebocyte lysate endotoxin.
8. Conclusion
Based on the intended use, materials, design, biocompatibility testing and performance testing, the material change of syringe piston meets the requirements that are considered essential for its intended use and the subject device is considered substantially equivalent to the predicate device, the EpiFaith Syringe, cleared under K182268.
Substantial Equivalence
The subject device has the same intended use, technology, operation principle and the technical characteristics with the predicate device. Design Verification activities were performed on subject device and all necessary tests were verified to meet the required acceptance criteria. The verification tests demonstrate that the differences in the material of syringe piston do not change the intended use of the device or raise different questions of safety and effectiveness. There are no significant differences between subject device and the predicate device(s) that would adversely affect the use of the product. We conclude that subject device is substantially equivalent to predicate devices.
