No
The summary describes standard image processing and mechanical functions, and there is no mention of AI, ML, or related concepts like training or test sets for algorithmic performance.
Yes
The device is described as enabling physicians to "perform procedures in the bladder and lower ureter for diagnosis and treatment," and allows for the "delivery and use of accessories such as biopsy forceps, laser fibers, graspers and retrieval baskets at a surgical site," which indicates a therapeutic purpose beyond just diagnosis.
Yes.
The device description explicitly states that the WiScope® Digital Cystoscope System is "designed for physicians to access, visualize, and perform procedures in the bladder and lower ureter for diagnosis and treatment." The term "diagnosis" directly indicates its use as a diagnostic device.
No
The device description explicitly states it includes a "single-use digital cystoscope" and describes physical components like a handle, deflection control, and insertion tube, indicating it is a hardware device with integrated software for image processing.
Based on the provided information, the WiScope® Digital Cystoscope System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use is to "access, visualize, and perform procedures in the bladder and lower ureter." This describes a device used in vivo (within the body) for direct visualization and intervention.
- Device Description: The description reinforces its use for "access, visualize, and perform procedures" and mentions it includes a "single-use digital cystoscope." Cystoscopes are instruments used to look inside the bladder.
- Lack of IVD Characteristics: IVD devices are typically used to examine specimens (like blood, urine, or tissue) outside the body to provide information for diagnosis, monitoring, or screening. The WiScope does not perform this function. It is a tool for direct visualization and procedural intervention within the body.
While the device uses image processing and a CMOS image sensor, which are technologies that can be used in IVD devices (e.g., for analyzing images of cells), in this context, they are used for real-time visualization during a procedure performed on a patient.

(a)
Identification. An endoscope and accessories is a device used to provide access, illumination, and allow observation or manipulation of body cavities, hollow organs, and canals. The device consists of various rigid or flexible instruments that are inserted into body spaces and may include an optical system for conveying an image to the user's eye and their accessories may assist in gaining access or increase the versatility and augment the capabilities of the devices. Examples of devices that are within this generic type of device include cleaning accessories for endoscopes, photographic accessories for endoscopes, nonpowered anoscopes, binolcular attachments for endoscopes, pocket battery boxes, flexible or rigid choledochoscopes, colonoscopes, diagnostic cystoscopes, cystourethroscopes, enteroscopes, esophagogastroduodenoscopes, rigid esophagoscopes, fiberoptic illuminators for endoscopes, incandescent endoscope lamps, biliary pancreatoscopes, proctoscopes, resectoscopes, nephroscopes, sigmoidoscopes, ureteroscopes, urethroscopes, endomagnetic retrievers, cytology brushes for endoscopes, and lubricating jelly for transurethral surgical instruments. This section does not apply to endoscopes that have specialized uses in other medical specialty areas and that are covered by classification regulations in other parts of the device classification regulations.(b)
