Intended Use

Electro Lube™ NXT is a single patient use device used in open and minimally-invasive surgery to reduce tissue sticking and eschar on electrosurgical instruments, including robotic assisted electrosurgical instruments.

Device Story

Electro Lube NXT is a sterile, single-use electrosurgical accessory consisting of a 4mL vial of lubricating solution and a foam applicator pad with an adhesive backing and radiopaque barium filament. Used in clinical environments by professional practitioners during open and minimally-invasive surgeries, including robotic-assisted procedures. The practitioner applies the solution to electrosurgical electrodes using the provided foam pad. The coating acts as a non-stick barrier to reduce tissue adhesion and eschar buildup on the instrument tip during electrosurgical cutting and coagulation. This reduces the need for frequent instrument cleaning during procedures, potentially improving surgical efficiency and maintaining instrument performance without negatively impacting thermal spread or impeding post-operative reprocessing/cleaning of the instruments.

Clinical Evidence

Bench testing only. Performance evaluations included tissue adhesion, eschar removal, cutting force, impedance, flash point, thermal spread, and reprocessing/cleaning validation for both standard and robotic-assisted electrosurgical instruments. Biocompatibility testing included cytotoxicity, sensitization, intracutaneous reactivity, acute systemic toxicity, hemocompatibility, and pyrogenicity.

Technological Characteristics

Materials: Lexolube® CQ-3000 (lubricant), polyester polyurethane foam, medical double-coated tape, barium cord, medium density polyethylene bottle. Sterilization: Irradiation (SAL 10^-6). Form factor: 4mL vial with applicator pad. Connectivity: None. Software: None.

Indications for Use

Indicated for use in open and minimally-invasive surgery, including robotic-assisted procedures, to reduce tissue sticking and eschar on electrosurgical instruments for single patient use.

Regulatory Classification

Identification

An electrosurgical cutting and coagulation device and accessories is a device intended to remove tissue and control bleeding by use of high-frequency electrical current.

Dear Steve Elliott:

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 (the 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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device"

Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30, Design controls; 21 CFR 820.90, Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).

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); medical device reporting (reporting of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reporting-combination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.

All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E). For additional information on these requirements, please see the UDI System webpage at https://www.fda.gov/medical-devices/device-advice-comprehensive-regulatory-assistance/unique-device-identification-system-udi-system.

## 3. Description of Device

Electro Lube NXT is a single-use sterile electrosurgical accessory device intended to be used on electrosurgical electrodes to reduce sticking. It is intended to be used by professional practitioners of electrosurgery in clinical environments where electrosurgery is performed.

Electro Lube NXT is sterilized by irradiation and provided to the end user in an individual sterile barrier package with one bottle containing 4mL of the solution and one foam pad for application of the solution during use included in each pack. The foam pad includes an adhesive backing and barium filament strand of material for radiopacity.
