VersaVue Single-Use Flexible Cystoscope, VersaVue Tablet, and VersaVue Video Box by Medimaging Integrated Solution Inc. (MiiS)

The VersaVue™ Single-Use Flexible Cystoscope is a sterile, single-use, and flexible device intended to be operated with its compatible display system (VersaVue™ Tablet OR VersaVue™ Video Box). The device provides endoscopic procedure and surgical treatment within the lower urinary tract.

The Cystoscope is intended to provide visualization via displaying unit.

The Cystoscope is intended for use in a hospital environment or medical office environment. It is designed for use in adults.

Device Description

VersaVue™ Single-Use Flexible Cystoscope is a single-use, flexible, sterile cystoscope. The illumination LED locate at the tip of the distal end. There is a bending section near the region of distal end, which manipulated by the control lever on the handle part, can provide visions with more than one direction for the users. The signal captured was then transmitted to the cable-connected display system (VersaVue™ Tablet OR VersaVue™ Video Box). The working channel provide access for accessories to conduct surgical process.

VersaVue™ Tablet is a tablet. The live imaging or snapshot will present directly on the tablet.

VersaVue™ Video Box is a standalone imaging transfer system, it can be connected to computer to project live imaging. The function of VersaVueTM Single-Use Flexible Cystoscope is to provide live imaging of the lower urinary tract, including tissue appearance recording, snapshot, vertical flip and horizontal flip.

AI/ML Overview

The provided text does not contain information about acceptance criteria for a device's performance that would require a study with a test set, expert adjudication, or MRMC studies. The document describes a 510(k) premarket notification for a cystoscope, focusing on substantial equivalence to a predicate device based on technical characteristics and nonclinical tests.

Therefore, I cannot provide the requested information. The document states:

"Clinical Tests
No clinical studies were performed."

This indicates that the submission did not include studies that would typically define acceptance criteria based on performance with a test set and ground truth. The listed nonclinical tests focus on safety, electrical compatibility, sterilization, and basic optical performance specifications, not on clinical performance metrics with a patient dataset.

Dear Luu Hsu:

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.

Substantial Equivalence Discussion

Similarities:

VersaVue™ Single-Use Flexible Cystoscope and the predicate device, Ambu aScope 4 Cysto (K193095), have the same intended use and similar specifications in field of view, direction of view, depth of field, bending angle, working length, outer diameter, working channel diameter, sterilization method, light source location and appearance.

Differences:

The differences lie in the optical specification (depth of field), bending angle, outer diameter of the insertion tube, working length and working channel diameter. Differences about most of these features are not more than 10%. Although the difference becomes bigger in the feature of depth of field, the usability test proves that image performance and the usability of the device are both acceptable during clinical use. Additionally, the materials of the subject device are different. The materials were tested. Thus, it is considered that there is no significance difference occurs between VersaVue™ Single-Use Flexible Cystoscope with its predicate devices.

Nonclinical Tests

The following tests have been performed in support of the substantial equivalence determination:

Electrical safety per IEC/EN 60601-1:2005/2006+A1:2012/2013+A2:2020/2021. -
Electromagnetic Compatibility per IEC/EN 60601-1-2:2014/2015+A1:2020/2021 ၊
