The Trident Resection Ablator is intended to be used in arthroscopic procedures for resection and ablation of soft tissue, and hemostasis of blood vessels.

Device Description

The Trident Resection Ablator is a combination of a 4.2mm Linvatec arthroscopic shaver blade and a Linvatec UltrAblator® monopolar electrode. The product configuration combines the mechanical resection of a shaver blade and the ablation and hemostasis functions of an electrode. The Trident Resection Ablator is supplied sterile, single use.

The modification to the Trident Resection Ablator described in this Special 510(k) is a change in the material formulation of the electrical insulation coating. This modification does not affect the device's intended use, fundamental scientific technology, performance specifications or labeling.

AI/ML Overview

This document is a 510(k) summary for the Trident Resection Ablator, a medical device. It focuses on demonstrating substantial equivalence to existing predicate devices rather than presenting a study to prove performance against specific acceptance criteria.

Therefore, the requested information elements related to performance studies (acceptance criteria table, sample sizes, expert ground truth, adjudication methods, MRMC studies, standalone performance, and ground truth for training sets) cannot be extracted from the provided text.

The document explicitly states that the modification to the Trident Resection Ablator is a "change in the material formulation of the electrical insulation." It also notes that "This modification does not affect the device's intended use, coating, fundamental scientific technology, performance specifications or labeling."

The basis for market clearance is that "Testing has been conducted to assure that the change in the material formulation of the insulation coating does not raise any new issues regarding safety and effectiveness." This testing is not detailed in terms of specific performance metrics or acceptance criteria as would be found in a clinical or analytical performance study. Instead, the focus is on confirming that the material change does not negatively impact the device's equivalence to existing, already cleared devices.

Dear Ms. Krejci:

We have reviewed your Scction 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially cquivalent (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 Mcdical 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 docs 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); labcling (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.
