The 'TC' is a microprocessor controlled Helium Thermal Coagulator. Working at 2 to 33 watts of power with Helium gas flows of 1 to 5 liters/minute depending on procedure and probe. The 'TC' automatically works with all of the flexible disposable probes. Models T, C, D, E, R, and S. (Size range 2.5mm to 4mm x 60 mm to 310mm)

AI/ML Overview

Please provide the full text of the study or report that proves the device meets the acceptance criteria. The provided document is a 510(k) summary for the Helica TC (Thermal Coagulator) and a clearance letter from the FDA, which describes the device and its intended use, and states that it has been found substantially equivalent to predicate devices. However, it does not contain the detailed study information needed to fill out all aspects of your request (e.g., specific acceptance criteria, study design, sample size for test/training sets, ground truth establishment, expert qualifications, MRMC studies, or standalone performance data).

The provided text only includes a comparison of the Helica TC with predicate devices regarding safety and performance, mentioning "Published studies show that gas-enhanced electrosurgery is safe effective" but not providing details about these studies or how they specifically relate to the Helica TC's acceptance criteria. It also lists compliance with electrical standards (IEC 601-1, IEC 601-2-2, ANSI/AAMI HF18) as a performance metric.

Therefore, without the actual study report, I cannot provide a complete answer to your request. If you can provide the study report, I would be happy to analyze it and extract the requested information.

SUMMARY OF EQUIVALENCY OF SAFETY AND EFFECTIVENESS

HELICA 'TC', VALLEY LAB. APEC AND ERBE APC 300

HELICA 'TC'

VALLEY LAB. APEC

ERBE APC 300

INTENDED USE:

Laparoscopic, Endoscopic, and open surgical procedures where Monopolar electrosurgery is normally used. Not intended for use on patients with right to left cardiac shunting.

PRODUCT DESCRIPTION:

In all cases probe is activated (foot control) in the gas-enhanced mode, A Helium plasma is created between the probe and the target tissue. This mode permits the user to coagulate tissue in a more controlled manner than with standard fulguration and the flow of inert gas produces the following additional beneficial effects: (1) The presence of inert gas at surgical site inhibits combustion with other gases (e.g., oxygen, nitrogen, etc.)

Use several generators Ranging from 40 to 120 Watts and Argon gas flows From 0.5 to 16 liters/minute .

Uses a number of hand sets Depending on procedure.

Does the same using Argon gas . Has both hand and foot controls. APC 300 generator Not specified Argon gas flows From 0.1 to 9 liters /minute.

Uses 3 specified Probes depending Type of operation.

Does the same Using Argon gas.

{1}------------------------------------------------

And the gas jet pushes any residual smoke or water vapor away from the site, thereby improving visibility, and (2) The gas jet pushes blood out of the way which significantly reduces the coagulation of blood on the surface of the tissue and provides the surgeon with improved visibility at surgical site.

Dear Dr. Webb:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). 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 (Premarket Approval), 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 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (OS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
