Intended Use
aScope 5 Cysto HD is a sterile, single-use, flexible cysto-nephroscope intended to be used for endoscopic access to and examination of the lower urinary tract and kidney. The cysto-nephroscope is intended to provide visualization via a compatible Ambu displaying unit and can be used with endoscopic accessories and instruments.
Device Description
The Ambu® aScope™ 5 Cysto HD is a sterile single-use and flexible endoscope for use within the lower urinary tract and kidney via antegrade (percutaneous) access. The cysto-nephroscope is intended to be used with a compatible and reusable Ambu displaying unit (the Ambu® aBox™ 2 or the Ambu® aView™ 2 Advance) to visualise the urethra and the bladder as well as the kidney. The cysto-nephroscope is powered by connecting to the displaying unit. Ambu® aScope 5 Cysto HD can be used with endoscopic instruments and accessories, for instillation of fluids (e.g. saline for expanding the bladder) and suctioning of fluids. Ambu® aScope 5 Cysto HD shall be disposed of as infected medical device with electronic components. Ambu® aScope 5 Cysto HD is available in one size and can be operated by either the left or right hand. Two variants of the cysto-nephroscope are available: aScope 5 Cysto HD - Reverse Deflection and aScope 5 Cysto HD - Standard Deflection. Apart from the mode of deflection, the cysto-nephroscopes share the same design.

No.

The document describes a sterile, single-use flexible cysto-nephroscope that provides visualization via a compatible displaying unit. There is no mention of AI, ML, or DNN within the device or its intended use, and the performance studies focus on physical and optical properties rather than computational or analytical capabilities.

No
The device is primarily intended for endoscopic examination and visualization of the urinary tract and kidney, not for actively treating a medical condition. While it can be used with endoscopic accessories and instruments, its core function is diagnostic, not therapeutic.

Yes

The device is intended for "endoscopic access to and examination" of anatomical sites and provides "visualization" to achieve this purpose. This directly aligns with the definition of a diagnostic device, which is used to identify or examine medical conditions.

No

The device is a physical, sterile, single-use, flexible endoscope with optical and electrical components intended for direct visualization. Its description and performance studies clearly indicate it is a hardware device, not software-only.

No.
The device is an endoscope used for direct visualization of anatomical sites, not for in vitro examination of specimens derived from the human body.

Dear Sanjay Parikh:

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"

Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30, Design controls; 21 CFR 820.90, Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reporting-combination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.

All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E). For additional information on these requirements, please see the UDI System webpage at https://www.fda.gov/medical-devices/device-advice-comprehensive-regulatory-assistance/unique-device-identification-system-udi-system.

Device Description Summary

21 CFR 807.92(a)(4)

The Ambu® aScope™ 5 Cysto HD is a sterile single-use and flexible endoscope for use within the lower urinary tract and kidney via antegrade (percutaneous) access. The cysto-nephroscope is intended to be used with a compatible and reusable Ambu displaying unit (the Ambu® aBox™ 2 or the Ambu® aView™ 2 Advance) to visualise the urethra and the bladder as well as the kidney.

The cysto-nephroscope is powered by connecting to the displaying unit. Ambu® aScope 5 Cysto HD can be used with endoscopic instruments and accessories, for instillation of fluids (e.g. saline for expanding the bladder) and suctioning of fluids. Ambu® aScope 5 Cysto HD shall be disposed of as infected medical device with electronic components.

Page 6

Ambu® aScope 5 Cysto HD is available in one size and can be operated by either the left or right hand. Two variants of the cysto-nephroscope are available: aScope 5 Cysto HD - Reverse Deflection and aScope 5 Cysto HD - Standard Deflection. Apart from the mode of deflection, the cysto-nephroscopes share the same design.

Intended Use/Indications for Use
