The summary describes a standard portable X-ray system and does not mention any AI or ML capabilities in the device description, intended use, or performance studies.
No.
The device is used for diagnostic imaging (taking X-rays) to assist in the examination and diagnosis of dental and oral structures, not for treatment.
Yes
The "Intended Use / Indications for Use" section explicitly states that the device is "intended for taking diagnostic dental x-rays" and "for dental radiographic examination and diagnosis of the teeth, jaw, and oral structure."
No
The device description explicitly states it is a "handheld x-ray device" with an "x-ray source, a tube, located inside the handheld device," indicating it is a hardware device that emits ionizing radiation.
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, such as blood, urine, or tissue, to detect diseases, conditions, or infections. These tests are performed outside the body (in vitro).
- Cocoon Device Function: The Cocoon device is an X-ray system. It uses ionizing radiation to create images of the teeth, jaw, and oral structure within the patient's body. This is an in vivo diagnostic imaging technique, not an in vitro test.
- Intended Use: The intended use clearly states it's for "taking diagnostic dental x-rays" and "dental radiographic examination and diagnosis." This involves capturing images of internal structures, not analyzing biological samples.
The information provided describes a medical imaging device, specifically a portable dental X-ray system, which falls under a different regulatory category than IVDs.

Device Description
Cocoon Portable X-ray System from Dexcowin Co., Ltd., of Seoul, Korea is a handheld x-ray device. The technology of this device was originally developed in Korea more than a decade ago and global production is still concentrated in that country. The subject device is designed for dental radiographic examination and diagnosis of diseases of the teeth, jaw, and oral structure by exposing an x-ray image receptor to ionizing radiation. The x-ray source, a tube, is located inside the handheld device. All three conventional types of intraoral receptors can be used with this device-analog x-ray film, digital phosphorous plates, and digital x-ray sensors.

Dear Ms. St. Germain:
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. 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.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies.
