No
The device description and performance studies focus on the physical, chemical, and biological properties of a collagen membrane, with no mention of AI or ML.
Yes
The device is described as a resorbable collagen membrane used to enhance preservation of the alveolar ridge by acting as a barrier to facilitate proper bone regeneration, which directly addresses a medical condition or ailment.
No
The device description indicates it is a resorbable collagen membrane used to act as a barrier for bone regeneration, which is a therapeutic function rather than a diagnostic one. The "Intended Use" also describes covering extraction sockets to enhance preservation, confirming its therapeutic purpose.
No
The device description clearly states it is a "Resorbable Collagen Membrane" made from "fibrous collagen matrix purified from porcine tendon," indicating it is a physical, implantable material, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to cover extraction sockets to enhance alveolar ridge preservation. This is a surgical/implantable device used directly on the patient's tissue.
- Device Description: The description details a resorbable collagen membrane acting as a physical barrier for tissue regeneration. This is a material implanted in the body.
- 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 samples) to provide information for diagnosis, monitoring, or screening. The device itself is the treatment/support for tissue regeneration.
- Performance Studies: The performance studies focus on the physical, chemical, mechanical, and biological properties of the membrane itself, as well as its in vivo performance in an animal model. These are typical evaluations for implantable or surgical devices, not IVDs.
In summary, the device's function and intended use are related to supporting tissue regeneration within the body, which is characteristic of a surgical or implantable device, not an in vitro diagnostic.

Device Description
THE Cover Resorbable Collagen Membrane is a white, pliable membrane consisting of fibrous collagen matrix purified from porcine tendon. THE Cover act as a barrier between the gingival and the new bone that can facilitate proper bone regeneration. As soft tissues tend to grow faster than the bone can regenerate, the membrane can help protect the bone graft particles from this faster growing connective tissue. As collagen membrane will be dissolved, no additional operation is necessary. THE Cover does not have a distinction between face and back.
THE Cover is available in various sizes.
| Size | Thickness |
|---|---|
| 15 x 20 mm | |
| 15 x 30 mm | 0.3 mm, 0.5 mm |

Dear Byungsun Kim:
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. In addition, FDA may publish further announcements concerning your device in the Federal Register.
