The VivaWave™ Microwave System is intended for coagulation of soft tissue
The VivaWave™ Microwave System consists of an external microwave generator and probe. The generator is manually set at the desired power levels by the operator. Procedure time is also preset by the operator. The generator is connected to the probe through a connector.
The external generator unit measures approximately ( 13"H x 17"W x 3.5"D) The exterior housing is formed of aluminum coated with plastic.
The unit contains electric circuits, circuit boards, and integrated control panel. The major components of the generator are cooling fans, power supply, microwave module and the front panel/control board assembly.
The probe is a specifically designed antenna coated with Teflon (PTFE). The probe is permanently attached to a cable that carries the energy from the generator to the tip of the probe. The proximal end of the cable has a connector that fits into the generator and allows the energy to be delivered to the probe.
I am sorry, but based on the provided text, there is no information about the acceptance criteria or a study that proves the device meets those criteria. The provided document is a 510(k) premarket notification letter from the FDA, a summary of the device, its intended use, and a comparison to predicate devices for substantial equivalence.
It outlines:
- The device name: VivaWave™ Microwave System
- Its intended use: Coagulation of soft tissue.
- That it consists of an external microwave generator and a probe.
- Electrical safety, electromagnetic compatibility, and biocompatibility testing were performed to comply with standards (EN60601-1, EN60601-1-2, ISO 10993).
However, it does not include:
- A table of acceptance criteria and reported device performance.
- Details on sample size, data provenance, or expert involvement in any studies.
- Information on adjudication methods.
- Data from multi-reader multi-case (MRMC) comparative effectiveness studies.
- Standalone algorithm performance.
- Specifics on ground truth establishment or training set details.
The document primarily focuses on establishing substantial equivalence to previously marketed devices based on indications for use, basic function, manufacturing methods, and materials, rather than presenting detailed performance study results against specific acceptance criteria.

Trade Name: VivaWave™ Microwave System Regulation Number: 21 CFR 878.4400 Regulation Name: Electrosurgical Cutting and Coagulation Device and Accessories Regulatory Class: II (two) Product Code: NEY and GEI Dated: May 8, 2002 Received: May 9, 2002
Dear Mr. Kim:
This letter corrects our substantially equivalent letter of June 18, 2002 regarding the regulation name and number for your device. The regulation number for product code NEY has been changed from 878.4350 to 878.4400.
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 (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. 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.

Page 2 - Mr. Steven Kim
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. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807): labeling (21 CFR Part 801): good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (sections 531-542 of the Act); 21 CFR 1000-1050.
This letter will allow you to continue marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (301) 594-4646. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97) you may obtain.
