Dear Maya Leib Shlomo:

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.

Device Name:
Anovo® Instrument ARM Curved Scissors and Anovo® Instrument ARM Hook Electrode

Classification:
Mountable Electromechanical Surgical System for Transluminal Approaches Product Code QNM, Class 2

Predicate Device:
Anovo® Instrument ARM Curved Scissors and Anovo® Instrument ARM Hook Electrode (K243182)

Description:
The Anovo Instrument ARM Curved Scissors and Anovo Instrument ARM Hook Electrode ("Subject Device") are optional instruments for the Anovo Surgical System.

The purpose of this submission is to update the product labeling of the Anovo Instrument ARM Curved Scissors and Anovo Instrument ARM Hook Electrode to include compatibility with the Anovo Surgical System Model 6Ne.

The Anovo Surgical System Model 6N and Model 6Ne are almost identical, with the main difference being in the user interface. Both models are endoscopic instrument control systems that are intended to assist in the accurate control of the Instrument ARMS during single site, natural orifice laparoscopic-assisted transvaginal benign surgical procedures.

Both system's models comprise a Surgeon Console operated by a non-sterile surgeon, two sterile instruments (Instrument ARMS) actuated by the non-sterile, Robotic Control Unit (RCU). Both systems allow the physician to operate the Instrument ARMS from the Anovo Surgeon Console by manipulating the ARMS Controllers under visual guidance.

Instrument ARM Curved Scissors and Anovo Instrument ARM Hook Electrode or any of the Anovo Surgical System Components for the scope of this submission.

**Performance Evaluation:**

In accordance with the Design Control process, risk analysis was conducted to evaluate the impact of the labeling modification to the predicate device.

Design validation in female cadaver models was performed to evaluate the compatibility of the FDA-cleared Anovo Instrument ARM Hook Electrode and Curved Scissors with the Anovo Surgical System 6Ne (an FDA-cleared system), which is an enhanced configuration of Model 6N, including an enhanced Surgeon Console and Robotic Control Unit. The Instrument ARM Hook Electrode and Curved Scissors used with the Anovo Surgical System model 6Ne met all the predefined specific requirements related to transvaginal clinical compatibility, performance, and safety.

**Conclusion:**

The subject of this 510(k) is to modify the labeling of the cleared Anovo Instrument ARM Curved Scissors and Anovo Instrument ARM Hook Electrode and include compatibility with the FDA-cleared Anovo Surgical System Model 6Ne.

The subject and predicate devices are identical in terms of intended use, indication for use, design, technology, and performance specifications. Based on the presented information, together with the Validation testing, it can be concluded that the subject Anovo Instrument ARM Curved Scissors and Anovo Instrument ARM Hook Electrode, when used with the Anovo Surgical System Model 6Ne, are substantially equivalent to the predicate device.
