Intended Use

The gi2000 electrosurgery unit (ESU) is intended to deliver electrosurgical outputs to perform cutting and/or coagulation, in flexible endoscopic applications.

Device Story

The gi2000 is an isolated output electrosurgical generator used in flexible endoscopic clinical settings. It converts electrical energy into high-frequency current (approx. 350 kHz) to perform monopolar cutting, monopolar coagulation, monopolar spray coagulation, and bipolar coagulation. The system consists of the generator unit, a control panel, and an operating foot switch; it is designed for use with validated off-the-shelf accessories, including handpiece electrodes and dispersive return pads. Operated by clinicians, the device provides high-frequency energy to tissue to achieve surgical goals. The output is controlled via the interface, allowing the physician to select modes and power settings (up to 220 Watts) to manage tissue effects such as depth of penetration and spot size. By providing precise electrosurgical energy, the device facilitates tissue management during gastrointestinal procedures, potentially improving surgical outcomes.

Clinical Evidence

No human clinical data. Evidence consists of three non-clinical performance studies: 1) Ex-vivo comparative study measuring spot size and depth of penetration against predicate and reference devices; 2) Ex-vivo accessory compatibility study using off-the-shelf endoscopic accessories; 3) In-vivo preclinical study in a swine model where a veterinarian surgeon evaluated performance across various modes and settings. Results confirmed the device performs as intended and is comparable to the predicate.

Technological Characteristics

Isolated output electrosurgical generator; 350 kHz frequency; 220W maximum power output. Features monopolar (cut, coag, spray) and bipolar modes. Includes control panel and foot switch. Software-controlled interface. Validated for use with standard endoscopic accessories. Sterilization not specified for the generator unit.

Indications for Use

Indicated for patients undergoing flexible endoscopic surgical procedures requiring tissue cutting and/or coagulation.

Dear William Bowers:

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"

## Device Description Summary - 21 CFR 807.92(a)(4)

The gi2000 is an electrosurgical generator for use in flexible endoscopic clinical settings, employing high-frequency energies to carry out cutting and coagulation of tissue during gastrointestinal surgical procedures. This isolated output electrosurgical unit (ESU) includes all standard features commonly utilized in a broad spectrum of gastrointestinal surgical procedures, encompassing monopolar cutting, monopolar coagulation, and monopolar spray coagulation, along with bipolar coagulation.

K250657
Page 2 of 2

The gi2000 consists of the high-frequency electrosurgical unit with control panel and an operating foot switch. The handpiece (electrodes) and dispersive pad (return electrode) are not included with the gi2000. Instead, device labeling lists optional pieces that have been validated with the device.

## Intended Use/Indications for Use – 21 CFR 80792(a)(5)

The gi2000 electrosurgery unit (ESU) is intended to deliver electrosurgical outputs to perform cutting and/or coagulation, in flexible endoscopic applications.

## Indications for Use Comparison – 21 CFR 807.92(a)(5)

The subject and predicate devices share the same intended use, indications for use, and have similar technical features and output performance.

## Technological Comparison – 21 CFR 807.92(a)(6)

The subject and predicate devices share the same fundamental technology: converting electrical energy into high-frequency current for surgical use. Both offer monopolar and bipolar modes at approximately 350 kHz and a maximum power output of 220 Watts. The general and technical characteristics that differ between the predicate and the subject device are differences in software (including the graphical user interface), number of control screens, and power consumption. These differences do not raise concerns about safety and effectiveness based on the results of performance testing.

A reference device is included to support the spray function. The reference device, the Valleylab Force FX-C, cleared under K944602, shares the same regulation number (21 CFR 878.4400) and product code (GEI) as the subject device. Both devices feature mono spray coagulation at approximately 350 kHz and a maximum power output of 110 Watts. Because spray coagulation is a feature of the legally marketed reference device, its performance values show that the subject device's spray coagulation performance values are similar and raise no new safety or effectiveness concerns.

## Non-Clinical Tests Summary & Conclusions – 21 CFR 807.92(b)

Performance testing on the gi2000 was completed by three methods. The first method was completed in an ex-vivo study which compared the gi2000 to the predicate device and the reference device. The study compared the spot size and the depth of penetration with comparative modes, power settings and activation times. Results of the study are recorded in 40-0036-11 DS, Predicate Device Comparative Study Report, gi2000.

The second method compared the gi2000 to the predicate device using an assortment of off-the-shelf accessories when applied to a flexible endoscope in an ex-vivo setting. Results of the study are recorded in 40-0036-15, DS, Accessory Compatibility Study Report, gi2000.

The third method compared the gi2000 to the predicate device in an in-vivo setting. The in-vivo test compared the gi2000 to the predicate device comparing the similarities (and variances) on a swine model. The veterinarian surgeon evaluated the performance of each generator using modes and settings as defined in 40-0036-13, DS, In-Vivo Preclinical Test Results, gi2000.

## Conclusion

The subject device has the same general intended use and principle of operation as the predicate device. The changes in device hardware and software do not raise different questions of safety or effectiveness. These changes have been verified and validated through nonclinical performance testing. Technological comparison and nonclinical performance testing have demonstrated that the subject device operates as intended and that it is as safe and effective as the predicates for the proposed indications for use.
