The PENTAX Medical EPK-i7010 Video Processor is intended to be used with the PENTAX camera heads, endoscopes, light sources, monitors and other ancillary equipment for gastrointestinal endoscopic diagnosis, treatment and video observation.
The PENTAX Medical EPK-i7010 includes a digital post-processing imaging enhancement technology (PENTAX i-Scan™) and an optical imaging enhancement technology (OE). These imaging enhancement technologies are intended to be used as an optional adjunct following traditional white light endoscopy and is not intended to replace histopathological sampling. i-Scan and OE are compatible with PENTAX Medical video gastrointestinal endoscopes.

The PENTAX EPK-i5010 includes PENTAX i-Scan™, a digital post-processing imaging enhancement technology. i-Scan is intended to be used as an optional adjunct following traditional white light endoscopy and is not intended to replace histopathological sampling. i-Scan is compatible with PENTAX k-series and i-series gastrointestinal videoscopes and colonovideoscopes.
The PENTAX Medical EPK-i7010 Video Processor and PENTAX EPK-i5010 Video Processor each consist of a video system, integrated light source, monitor, and ancillary equipment. These processors are intended for gastrointestinal endoscopic diagnostic, treatment and video observation.
The PENTAX Medical EPK-i7010 Video Processor contains two types of contrast enhancement techniques: PENTAX i-Scan technology, and optical enhancement (OE) technology. The PENTAX EPK-i5010 Video Processor contains only PENTAX i-Scan. The PENTAX i-Scan technology is a digital post-processing image enhancement technique with three modes, i-Scan 1, 2 and 3.
The provided text is a 510(k) summary for the PENTAX Medical EPK-i7010 and EPK-i5010 Video Processors, with a focus on a minor design change related to the Water Bottle Assembly OS-H5. It is NOT a study proving the device meets acceptance criteria for an AI/imaging diagnostic device.
The document discusses performance testing in a general sense, but this testing relates to the physical and functional characteristics of the water bottle accessory and its reprocessing, not to the diagnostic accuracy or clinical performance of the imaging enhancement technologies (i-Scan and OE) with human readers.
Therefore, many of the requested criteria for describing an AI/imaging diagnostic study (e.g., sample size for test set, number of experts for ground truth, MRMC study, effect size) cannot be found in this document because the document does not describe such a study.
The closest relevant information relates to the performance of the Water Bottle Assembly OS-H5.
Here's an attempt to answer the questions based only on the provided text, highlighting where information is absent:
Acceptance Criteria and Study for PENTAX Medical EPK-i7010/EPK-i5010 (Water Bottle Assembly OS-H5)
The provided document (510(k) summary) does not describe a study related to the diagnostic performance of the PENTAX i-Scan or Optical Enhancement (OE) technologies, especially in conjunction with human readers or AI algorithms. Instead, it focuses on demonstrating the substantial equivalence of the PENTAX Medical EPK-i7010 and EPK-i5010 Video Processors, specifically addressing a minor design change: the replacement of a disposable water bottle system with the reusable PENTAX Water Bottle Assembly OS-H5.
The "acceptance criteria" and "study" described pertain to the safety and functional performance of the reusable water bottle accessory and its reprocessing methods, not the diagnostic utility of the imaging processors themselves or any associated AI.

§ 876.1500 Endoscope and accessories.
(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)
Classification —(1)Class II (special controls). The device, when it is an endoscope disinfectant basin, which consists solely of a container that holds disinfectant and endoscopes and accessories; an endoscopic magnetic retriever intended for single use; sterile scissors for cystoscope intended for single use; a disposable, non-powered endoscopic grasping/cutting instrument intended for single use; a diagnostic incandescent light source; a fiberoptic photographic light source; a routine fiberoptic light source; an endoscopic sponge carrier; a xenon arc endoscope light source; an endoscope transformer; an LED light source; or a gastroenterology-urology endoscopic guidewire, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 876.9.(2) Class I for the photographic accessories for endoscope, miscellaneous bulb adapter for endoscope, binocular attachment for endoscope, eyepiece attachment for prescription lens, teaching attachment, inflation bulb, measuring device for panendoscope, photographic equipment for physiologic function monitor, special lens instrument for endoscope, smoke removal tube, rechargeable battery box, pocket battery box, bite block for endoscope, and cleaning brush for endoscope. The devices subject to this paragraph (b)(2) are exempt from the premarket notification procedures in subpart E of part 807of this chapter, subject to the limitations in § 876.9.
