Intended Use

The EvoEndo Model LE Gastrocope is intended for the visualization of the upper digestive tract in adults and pediatric patients, specifically for the observation, diagnosis, and endoscopic treatment of the esophagus, stomach, and duodenal bulb. The gastroscope is a sterile single-use device and can be inserted orally or transnasally. The 110 cm gastroscope is intended to be used in adult and pediatric populations. The 85 cm gastroscope is intended to be used in the pediatric population. The EvoEndo Controller is intended for use with an EvoEndo Endoscope for endoscopic diagnosis, treatment, and video observation.

Device Story

Single-use flexible gastroscope system; includes endoscope, reusable video cable, and controller. Endoscope features HD camera at distal tip; 4-way steering; air/water/suction channels. Controller processes video signals from endoscope for display on external medical-grade monitor. Used by clinicians for upper GI endoscopy (oral/transnasal). Provides real-time visualization for diagnosis and treatment. Benefits include elimination of reprocessing requirements via single-use design; improved maneuverability compared to predicate. Firmware enables image enhancement (gamma correction), freeze, and white-balance functions.

Clinical Evidence

No clinical or animal studies conducted. Evidence based on bench testing, including biocompatibility (ISO 10993-1), functional verification (tip deflection, flow rates, transit simulation), electrical safety (IEC 60601-1), and usability engineering study with representative users.

Dear Keira Jessop:

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"

# 1.7 Performance Testing Summary

## Summary of Biocompatibility Testing

The EvoEndo Model LE Gastroscope is considered to be a surface device with breached or compromised surfaces contact with a limited duration (< 24 hrs). The biocompatibility evaluation for the EvoEndo Model LE Gastroscope was conducted in accordance with the guidance document “Use of International Standard ISO 10993-1, ‘Biological Evaluation of Medical Devices Part 1: Evaluation and Testing Within a Risk Management Process,’” The testing included the following:

- Cytotoxicity
- Sensitization
- Irritation
- Acute Systemic Toxicity
- Material Medicated Pyrogenicity

## Summary of Non-Clinical Functional and Performance Testing

Visual, dimensional, functional, and transit simulation verification testing was performed on final sterilized EvoEndo Endoscopes. In functional testing, devices were verified for camera and video control unit functioning; tip deflection; air, water, and suction flow rates; functionality with accessory device; functionality after 360° bend shaft orientation; functionality with simulated repeated use; and post simulated use functionality. The maximum bending angle of the device in each direction is shown in the table below. The deflection achieved with the EvoEndo Endoscope is considered equal or greater to that of the identified predicate device in all directions, indicating substantial equivalence.

Table 3: Deflection of EvoEndo Endoscope

| Deflection Direction | Maximum Bending Angle |
| --- | --- |
| Up | 210° |
| Down | 90° |
| Left | 180° |
| Right | 180° |

In transit simulation testing, test units underwent environmental conditioning, distribution simulation, and packaging testing to confirm the integrity of the sterile barrier and functionality of the device under expected transportation conditions. The EvoEndo Endoscopy System met acceptance criteria set for all verification testing procedures.

Photobiological safety testing was performed per FDA recognized consensus standard IEC/TR 62471 First Edition 2006-07: Photobiological safety of lamps and lamp systems. Based on the measured output of the EvoEndo's light source, it was

{10}

Page 7 of 7

deemed to be below the limits of the exempt risk group.

## Summary of Usability Engineering Testing:

EvoEndo conducted a usability study of representative intended users. The study assessed the overall usability of the EvoEndo Endoscopy System and the ability for users to perform critical tasks. Participants were asked to perform the entire workflow of the device across a benchtop model with prior training provided. Throughout the procedure, there were no significant device or user malfunctions or errors that would result in patient harm during an actual procedure.

## Summary of Animal and Clinical Data

No animal or clinical studies were conducted for this submission.

## 1.8 Shelf Life and Sterilization

The EvoEndo Endoscope is packaged individually, provided sterile, labeled for single use only, and sterilized using 100% ethylene oxide (EO) gas in a fixed chamber. Validation performed for the sterilization technique met all acceptance criteria. Functional testing confirmed that sterilization did not impact product safety or effectiveness. The predicate device (K213606) was cleared with a shelf life of 6 months. Additional testing done using the same methods as the predicate in K213606 was performed. Based on the testing performed the labeled shelf life will be 12-months.

## 1.9 Electrical Safety and EMC Testing:

The Electrical Safety (ES) and Electromagnetic Compatibility (EMC) testing conformed to IEC 60601-1 Ed. 3.2 en:2020, IEC 60601-1-2:2014/AMD1:2020, IEC 60601-2-18:2009, and IEC 62471, Ed 1.0 (2006-07). All acceptance criteria were met.

## 1.10 Software Testing:

The firmware used in the EvoEndo Controller has been determined to be a basic level of concern. The software in the controller, consisting of 6 embedded firmware items, is considered off-the-shelf software and, as such, is documented in accordance with the FDA Guidance "Off- The-Shelf Software Use in Medical Devices" (August 2023).

## 1.11 Conclusion

In accordance with the Federal Food, Drug and Cosmetic Act, 21 CFR Part 807 and based on the information provided in this premarket notification that it can be concluded that the subject device is substantially equivalent with predicate device.
