The device description and performance studies focus on the physical and material properties of a manually operated syringe, with no mention of AI or ML.
No
A therapeutic device is one that treats or heals a medical condition. This device is a syringe, used for injecting or withdrawing fluids, which is a delivery mechanism, not a treatment in itself.
No
The device description and intended use clearly state that the syringe is used to inject or withdraw fluids, which are therapeutic or procedural actions, not diagnostic ones. There is no mention of analysis, measurement, or assessment for diagnostic purposes.
No
The device description clearly outlines a physical medical device consisting of a barrel, plunger, and needle, made of plastic and silicone. There is no mention of software as a component or the primary function of the device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to "inject fluid into or withdraw fluids from the parts of body below the surface of the skin." This describes a direct interaction with the body for therapeutic or diagnostic purposes within the body, not for testing samples outside the body.
- Device Description: The description details a syringe with a needle for injecting or withdrawing fluids from the body. This is consistent with a device used for administering substances or collecting samples directly from a patient.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue) in vitro (outside the body) to provide information for diagnostic, monitoring, or compatibility purposes.
IVD devices are specifically designed for testing samples in vitro to gain information about a person's health. This syringe is designed for direct interaction with the patient's body.

Summary of Performance Studies
- Biocompatibility Testing: In accordance with ISO 10993-1, the device is classified as: Externally Communicating Device, Blood Path Indirect, Limited Contact ( and met acceptance criteria.
- Physical Performance Testing: Standards applied were ISO 7864:2016 (Sterile hypodermic needles), ISO 7886-1:2017 (Sterile hypodermic syringes), and ISO 9626:2016 (Stainless steel needle tubing).
- Sterility, Shipping and Shelf-Life: Sterilization by Ethylene Oxide (EO not detected, ECH not detected), validation by Overkill Approach (Half-Cycle method), pyrogen test per USP and USP . Package integrity testing was performed after environmental conditioning and simulated transportation using ASTM D4169-22. Sterile Barrier Packaging Testing included Seal peel test ASTM F88/F88 -15 O and Dye migration- ASTM F1929-15 o. Shelf life of 3 years validated using ASTM F1980-21.
- Clinical Studies: Not required to support substantial equivalence.
Key Results: The proposed device was found to be substantially equivalent to the predicate device despite differences in needle length, with performance confirmed by accelerated aging tests. The differences between the predicate device and the subject device do not raise any new or different questions of safety or effectiveness.

Dear Peter Chung:
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.

VI. Comparison of technological characteristics with the predicate device
6
Note 1: Needle length
The needle length of proposed device is different from the needle of predicate device. In order to confirm the performance between the different needle specifications, the proposed device was verified by measuring the needle length at each time point of accelerated aging test. The proposed device was found to be substantially equivalent to the predicate device.
