No
The summary describes a bioabsorbable stent for maintaining sinus patency after surgery. There is no mention of AI, ML, image processing, or any other technology typically associated with AI/ML in medical devices. The focus is on the physical properties and function of the stent.

Yes
The device is intended to maintain patency of the sinus by separating mucosal tissues, providing stabilization of the middle turbinate, and preventing obstruction by adhesions, which are all therapeutic actions.

No
The device is a bioabsorbable stent used to maintain patency of the sinus after surgery, separating tissues and preventing obstruction. It is a therapeutic device, not a diagnostic one.

No

The device description clearly states it is a "bioabsorbable stent," which is a physical hardware component, not software.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health. These tests are performed outside of the body.
  • Sinexus Sinus Stent Gen 2 Function: The description clearly states that the Sinexus Sinus Stent Gen 2 is a bioabsorbable stent designed to be placed in the ethmoid sinus after surgery. Its purpose is to maintain patency and prevent obstruction within the body.

The device is a surgical implant used in vivo (within the body), not a diagnostic tool used in vitro (outside the body).

Dear Ms. Conuel:

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 additional controls.
