The PENTAX Medical Video Processor EPK-i8020c is intended to be used with the PENTAX Medical camera heads, endoscopes, light sources, monitors and other ancillary equipment for gastrointestinal endoscopic diagnosis, treatment and video observation.

The PENTAX Medical EPK-i8020c includes a digital post-processing imaging enhancement technology (PENTAX i-ScanTM), and 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 Medical Video Upper Gl Scope EG29-i20c is intended to provide optical visualization of (via a video monitor), and therapeutic access to, the upper gastrointestinal tract. This anatomy includes the organs; tissues; and subsystems: esophagus, stomach, and duodenum.

This endoscope is introduced via the mouth when indications consistent with the need for the procedure are observed in patient populations with greater than 20 kg of body weight.

The PENTAX Medical Video Colonoscope EC38-120cL is intended to provide optical visualization of (via a video monitor), and therapeutic access to, the lower gastrointestinal tract. This anatomy includes the organs, tissues, and subsystems: Large Bowel to the cecum, terminal ileum of the small bowel.

This endoscope is introduced via the rectum, as decided by the physician, when indications consistent with the need for the procedure are observed in patient populations with greater than 20 kg of body weight.

The PENTAX Medical Video Processor EPK-i8020c is intended to be used with PENTAX Medical endoscopes, monitors and other peripheral devices for endoscopic diagnosis, treatment, and video observation. The video processor consists of a video system, integrated light source, monitor, and ancillary equipment.

The EPK-i8020c includes a digital post-processing imaging enhancement technology (PENTAX Medical i-scan™) and an optical imaging enhancement technology (OE). These post-imaging functions are not intended to replace histopathological sampling.

The brand name "INSPIRA™" is provided for the EPK-i8020c video processor and the name is supposed to be found in the instructions for use (IFU) and/or in the commercial materials such as brochures.

The PENTAX Medical Video Upper GI Scope EG29-i20c is designed to be used with a PENTAX Medical Video Processor, video monitor, endoscopic devices such as biopsy forceps and other ancillary equipment for optical visualization (via a video monitor) of, and/or therapeutic access to the upper gastrointestinal tract.

The PENTAX Medical Video Colonoscope EC38-i20cL is designed to be used with a PENTAX Medical Video Processor, video monitor, endoscopic devices such as biopsy forceps and other ancillary equipment for optical visualization (via a video monitor) of, and/or therapeutic access to the lower digestive tract. The device is equipped with stiffness setting mechanism for the insertion tube. This feature enables the physician to choose the stiffness of the insertion tube, depending on the preferred level.

The document provides information on the PENTAX Medical EPK-i8020c Video Imaging System, including its components (Video Processor EPK-i8020c, Video Upper GI Scope EG29-i20c, and Video Colonoscope EC38-i20cL) and their intended uses. It also details the non-clinical performance data used to support the substantial equivalence determination to predicate devices.

However, the document does not contain the specific details required to answer all parts of your request, particularly regarding detailed acceptance criteria, reported device performance metrics in a table, an AI component, and the specifics of a study proving the device meets acceptance criteria in the way you've outlined.

The document primarily focuses on demonstrating substantial equivalence to existing predicate devices through various technical and performance tests, rather than setting and meeting a specific set of quantitative acceptance criteria for a new clinical performance claim or an AI algorithm.

Here's what can be extracted and what is missing:

Acceptance Criteria and Device Performance Study (Based on provided document)

The document describes various non-clinical performance tests to demonstrate substantial equivalence, rather than a single study with specific acceptance criteria for a novel AI feature. The "acceptance criteria" here are generally compliance with recognized standards or demonstration of equivalence to predicate devices.

1. A table of acceptance criteria and the reported device performance

2. Sample size used for the test set and the data provenance

The document does not specify a "test set" in the context of clinical images or patient data for an algorithm. The non-clinical tests mentioned rely on physical devices, simulated use, and animal models.

• For Reprocessing Validation: Simulated use testing. Sample size not specified.
• For Biocompatibility: Materials assessed in accordance with ISO standards. Sample size not specified.
• For Animal Image Capture Study: Animal model used. Sample size not specified.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

Not applicable as there is no mention of a human-expert-annotated "test set" for an AI algorithm or clinical performance study. The ground truth for the non-clinical tests is based on objective measurements, standards, or comparison to established predicate devices/methods.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Not applicable.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

No MRMC study or AI assistance claim is described in the provided document. The device includes "digital post-processing imaging enhancement technology (PENTAX i-Scan™)" and "optical imaging enhancement technology (OE)", but this is described as an "optional adjunct following traditional white light endoscopy" and "not intended to replace histopathological sampling." It is not presented as an AI-assisted diagnostic tool that would typically undergo an MRMC study to compare human performance with and without AI.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

This document does not describe the performance of a standalone algorithm for diagnostic purposes. The imaging enhancements (i-Scan, OE) are adjuncts for visual inspection by a clinician.

7. The type of ground truth used

For the non-clinical performance tests:

• Reprocessing Validation: AAMI TIR 30:2011 for residual soil accumulation and extraction efficiency.
• Biocompatibility: ISO 10993-1:2018 (toxicity, sensitization, intracutaneous reactivity).
• Electrical Safety and EMC: IEC and ISO standards.
• Optical Performance/Animal Image Capture Study: Comparison against predicate and reference devices' images and visualization capabilities.

No histological pathology or specific clinical outcomes data are mentioned as ground truth for a diagnostic performance study.

8. The sample size for the training set

Not applicable. There is no mention of an AI algorithm requiring a training set in this submission. The imaging enhancement technologies are likely rule-based image processing or optical filtering techniques rather than deep learning AI.

9. How the ground truth for the training set was established

Not applicable.
