The VivaTip Microwave Ablation Probe is a needle-like device that is inserted into soft tissue and coagulates a volume of tissue surrounding the active area of the probe. The probe is to be used with the VivaWave™ microwave power generator. Accessories to assist in cooling the shaft of the probe and to hold multiple probes together for simultaneous ablation are included.

AI/ML Overview

This premarket notification (510(k)) does not contain the requested information about acceptance criteria and a study proving the device meets those criteria. The provided text is a 510(k) summary and the FDA's response letter, which primarily focuses on establishing substantial equivalence to predicate devices rather than providing detailed performance study results against specific acceptance criteria.

Here's what can be inferred and what is explicitly missing from the provided text:

Inferences from the provided text:

Device Type: Microwave Ablation Probe. The purpose is for coagulation of soft tissue.
Regulatory Pathway: 510(k), which implies that the device is being compared to substantially equivalent predicate devices rather than proving safety and effectiveness de novo through extensive clinical trials.
Substantial Equivalence: The FDA determined the device to be substantially equivalent to the predicate devices (VivaWave™ Microwave Ablation System K011676 and Tri-Loop™ Microwave Ablation Probe K032047) based on "indications for use, basic overall function, methods of manufacturing, and materials used." This suggests that the performance characteristics (e.g., coagulation size, temperature profile) are considered similar enough to the predicates that a new detailed study proving specific acceptance criteria might not have been a primary requirement for this 510(k) clearance.

Missing Information (and why it's missing from this type of document):

The provided text is a 510(k) summary, which is a high-level overview. Detailed performance studies and acceptance criteria are typically found in the full 510(k) submission, which is not publicly available in its entirety. The summary focuses on establishing equivalence rather than detailing internal validation studies.

Therefore, I cannot provide the requested table or detailed study information based solely on the provided text. To answer your questions, I would need access to the full 510(k) submission document, particularly the sections related to performance testing and validation.

Re: K032702

Trade/Device Name: VivaTip™ Microwave Ablation Probe and Accessories Regulation Number: 21 CFR 878.4400 Regulation Name: Electrosurgical cutting and coagulation device and accessories Regulatory Class: II Product Code: GEI Dated: August 29, 2003 Received: September 3, 2003

Dear Mr. 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 (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.

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 (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
