Device Description

The FLOW 90 Wand is a bipolar, RF electrosurgical device designed for resection, ablation, and coagulation of soft tissue, and hemostasis of blood vessels in arthroscopic and orthopedic procedures. The FLOW 90° Wand is compatible with Qualified controllers (WEREWOLF® COBLATION® Systems (includes WEREWOLF® (K162074), WEREWOLF® ENT, (K192027) and WEREWOLF® + (K210423)) and INTELLIO® SHIFT ® System (K232290)).

The FLOW 90 Wand consists of a handle, shaft, integrated cable, and suction tubing. The integrated cable and suction tubing are attached at the proximal end of the handle and connect to the Qualified Controller and the Fluid Outflow Regulator of the Controller, respectively. No design changes have been made to the Qualified Controllers to support the use of the modified FLOW 90 Wand.

AI/ML Overview

The provided text is a summary of a 510(k) premarket notification for a medical device called the FLOW 90° Wand. It describes the device, its intended use, and its comparison to a predicate device. However, it does not contain any information about acceptance criteria or a study proving device performance in the context of an AI/ML device.

The relevant section, "NON-CLINICAL Testing," mentions electrical safety and bench testing (flow rate, fluid ingress, suction tube kinking, finger switch testing, and packaging validation), but these are for a physical electrosurgical device, not an AI/ML system.

Therefore, I cannot provide the requested information as it is not present in the given document.

Dear Srividya Pothana:

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/cdrb/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" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510/k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

COMPARISON OF THE TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE(S)

Technological Differences with Predicate

This Special 510(k) submission supports the design changes within the subject device's handle assembly and interface between finger switches and button pad to improve the device's ability to withstand clinical conditions related to fluid exposure and finger switch (button) actuation. A new packaging tray was also qualified as part of this submission to better secure the wand at its proximal end during transit.

Some additional differences between subject FLOW 90 Wand and predicate FLOW 90 (K183346) included as part of Letter to Files submissions are:

Indications for use Shoulder acromioplasty is removed as an indication of use, this change does . not affect the intended use, safety, and effectiveness of the device.
. Controller - The compatible qualified controllers include WEREWOLF ENT, WEREWOLF+ and INTELLIO SHIFT.

The modifications made to support the changes do not impact the device's intended use, fundamental scientific technology, and principle of operation and is substantially equivalent to previously cleared K183346 510(k) submission.

Some additional similarities between subject FLOW 90 Wand and predicate K183346 510(k) submission include:

Patient Contacting Materials: Both subject and predicate FLOW 90 Wands have equivalent patient contacting materials for the ceramic spacer, shaft, shaft insulation, adhesive, internal suction tubing and suction tube set.

Wand Specifications: The subject and predicate have the same wand specifications for suction ports, number of electrodes and handle lengths and outer diameter of the shaft.

NON-CLINICAL Testing

Electrical Safety: Basic safety and performance testing was performed on the proposed FLOW 90 Wand to demonstrate electrical, mechanical and functional capabilities in accordance with IEC 60601-1 and IEC 60601-2-2.

Bench testing: Mechanical Integrity and Functional Testing was performed, including testing results for flow rate, fluid ingress, suction tube kinking, and finger switch testing which are identified in the attachments.

Additionally, the new packaging tray was validated in accordance with ASTM D4169-DC13. ISO 11607-1, and ISO 11607-2.

Testing demonstrated the safety and efficacy of subject FLOW 90 Wand is substantially equivalent to its predicate device. All design inputs have been met and the testing performed did not introduce any new questions of safety or effectiveness.

CONCLUSION

All testing demonstrates that the proposed device performs as intended and has acceptable performance when used in accordance with its labeling. As the intended use, principle of operation, performance and fundamental scientific technology are unchanged from the predicate device the subject FLOW 90 Wand is substantially equivalent to the predicate device.
