Not Found

No
The device description and performance studies indicate a simple mechanical instrument for retraction, with no mention of AI/ML or related concepts like image processing or data analysis.

No
The device is described as a surgical instrument for retraction, which is a procedural tool rather than a device intended to treat or cure a disease or condition.

No

Explanation: The device is described as an instrument for retraction, which is a therapeutic or surgical action, not a diagnostic one. The performance studies focus on physical equivalency and retraction ability, further supporting its non-diagnostic nature.

No

The device description clearly states it is a "single use ophthalmic device designed to retract eye muscles," which is a physical instrument, not software. The performance studies also focus on physical properties like dimensional equivalency and retraction tension.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use/Indications for Use: The device is described as a "single use instrument for the retraction of eye muscles in various ophthalmic procedures." This clearly indicates a surgical or procedural use on a living patient, not a test performed on a sample taken from the body.
  • Device Description: The description reinforces this by stating it's a "single use ophthalmic device designed to retract eye muscles."
  • Lack of IVD Characteristics: The description does not mention any of the typical characteristics of an IVD, such as:
    • Analyzing samples (blood, urine, tissue, etc.)
    • Detecting or measuring substances in samples
    • Providing information for diagnosis, monitoring, or screening based on sample analysis

The device is a surgical instrument used directly on the patient during a procedure.

Dear Ms. Johnson:

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. 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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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.
