The PENTAX Medical EG-J10U Endoscopic Ultrasound System is intended to provide optical visualization of, ultrasonic visualization of, and therapeutic access to, the Upper Gastrointestinal Tract including but not restricted to the organs, tissues, and subsystems: Esophagus, Stomach, Duodenum and underlying areas. The instrument is introduced per orally when indications consistent with the requirement for procedure are observed in adult and pediatric patient populations.

The EG34-J10U, EG36-J10UR and EG38-J10UT Ultrasound Upper GI Video Scopes, are endoscopes used to provide visualization of, and therapeutic access to, the upper gastrointestinal tract. They are used with cleared Pentax Video Processors (a softwarecontrolled device) and cleared Hitachi Ultrasound Scanners (a software-controlled device). The endoscopes have a flexible insertion tube, a control body, PVE umbilical connector, and ultrasound scanner umbilical connector. The PVE umbilical connector will be attached to the Video Processor and has connections for illumination, video signals, air/ water/ and suction. The ultrasound scanner umbilical connector will be attached to the ultrasound scanner unit. A sterile, single use disposable natural rubber latex balloon is fitted over the convex array ultrasound transducer prior to the procedure. During an ultrasound endoscopy procedure, the latex balloon is inflated with water. The water that is contained within the balloon creates a water field that covers the transducer. The water field enables more effectively transport of ultrasonic pulses from the ultrasound transducer to the target anatomical site and back to the ultrasound transducer. The control body includes controls for up/ down/ left/ right angulation, air/ water delivery, and an accessory inlet port. The endoscope contains light carrying bundles to illuminate the body cavity, a charge couple device (CCD) to collect endoscopic image data, and a linear or radial array ultrasound transducer to collect ultrasonic image data. The instrument contains a working channel through which biopsy devices, or other devices, may be introduced.

The provided text is a 510(k) premarket notification for the PENTAX Medical EG-J10U Endoscopic Ultrasound System. This document focuses on demonstrating substantial equivalence to a predicate device rather than presenting a detailed study proving the device meets specific acceptance criteria in the context of an AI/ML medical device.

Therefore, many of the requested details, such as sample sizes for test sets, data provenance, number of experts for ground truth, adjudication methods, MRMC studies, standalone algorithm performance, and training set information (which are typical for AI/ML device submissions), are not present in this document.

The document primarily addresses hardware, software, and reprocessing aspects of the endoscopic ultrasound system. The "performance data" mentioned refers to non-clinical testing for functionality, safety, human factors, reprocessing validation, sterilization, shelf life, software verification/validation, EMC, electrical safety, and optical testing, rather than clinical performance metrics for a diagnostic or AI/ML algorithm.

Here's an attempt to answer the questions based on the available information, noting significant gaps:

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

The document describes performance testing in general terms rather than specific quantifiable acceptance criteria with corresponding results in a table format. It states that the system "has been successfully tested for its functions, performance and safety as per FDA recognized consensus standards." For optical testing, it notes "All results show that there are no differences between the subject device, and the predicate device."

2. Sample sizes used for the test set and the data provenance:

• Sample Size: Not specified in the document for any of the non-clinical tests.
• Data Provenance: Not specified. The tests are described as being conducted "as a part of Design Verification and Validation" and for "support of the substantial equivalence determination," implying internal company testing rather than clinical trials.

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

• Not applicable / Not specified. This document describes a medical device, not an AI/ML algorithm that requires expert ground truth for diagnostic accuracy. The "human factors" study involved reprocessing staff, not clinical experts establishing ground truth for diagnostic images.

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

• Not applicable / Not specified. No adjudication method is mentioned as it's not a diagnostic AI/ML study.

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. This is not an AI-assisted device. The document does not describe any MRMC studies or human reader improvement with AI assistance.

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

• Not applicable. This is not an AI/ML algorithm. The device is a physical endoscope with associated control software.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc):

• Not applicable. The "ground truth" for this device's performance testing would be engineering specifications, industry standards (e.g., IEC standards for electrical safety), and validated reprocessing protocols, rather than clinical ground truth for disease states.

8. The sample size for the training set:

• Not applicable. This document describes a medical device, not an AI/ML algorithm requiring a training set.

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

• Not applicable. As above, no training set for an AI/ML algorithm is described.

The provided text is a 510(k) Summary for the PENTAX Medical Ultrasound Video Bronchoscope EB19-J10U. It details the device's technical specifications, intended use, and a summary of testing conducted to demonstrate substantial equivalence to predicate devices. However, it does not contain any information about a study proving that the device meets specific acceptance criteria based on performance metrics like sensitivity, specificity, accuracy, or reader performance with or without AI assistance.

The document focuses on non-clinical testing to demonstrate that the device is equivalent to a legally marketed predicate device, especially regarding safety and effectiveness from a design and manufacturing perspective. It mentions "Performance Testing - Bench" for "System compatibility" and "Optical characteristics," but does not provide specific acceptance criteria or quantitative results for these tests.

Therefore, I cannot fully answer your request for acceptance criteria and a study that proves the device meets them, as the provided text does not include the necessary information regarding a clinical performance study involving AI, human readers, or specific diagnostic performance metrics.

Here's an breakdown of what can and cannot be answered based on the provided text:

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

• Cannot be provided. The document lists various types of non-clinical testing (Sterilization, Reprocessing, Biocompatibility, Software, EMC + Electrical Safety, System Compatibility, Optical Characteristics), and states that "Testing results confirm the subject device is safe and effective as the predicate device, and performs as intended." However, it does not provide specific quantitative acceptance criteria or detailed numerical results for these tests. For example, it says "The subject device demonstrates equivalent or better optical characteristics than the predicate device," but gives no numerical value for either.

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

• Cannot be provided definitively for a performance study. The document outlines non-clinical bench testing. These tests typically don't involve "samples" in the same way clinical studies do (e.g., patient data). The data provenance (country of origin, retrospective/prospective) is not applicable or mentioned for the types of tests described.

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

• Not applicable. This information is relevant for studies establishing diagnostic ground truth, often used for AI/clinical performance evaluations. The document describes engineering and safety testing, not clinical diagnostic performance.

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

• Not applicable. Adjudication methods are used in clinical studies to resolve discrepancies in expert interpretations for ground truth establishment. This document doesn't describe such a study.

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, such a study was not done according to this document. This device is a bronchoscope, which is a physical instrument for visualization and access, not an AI software intended to assist human readers in image interpretation. The document does not mention any AI component or any MRMC studies.

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

• No, this is not an AI algorithm. This is a hardware device (bronchoscope) with associated software for its operation. Therefore, a standalone algorithm performance study is not applicable.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

• Not applicable in the context of diagnostic performance. The "ground truth" for the tests described relates to engineering specifications and safety standards (e.g., whether the device sterilizes correctly, whether electrical current is within safe limits, whether optical clarity meets design specs).

8. The sample size for the training set:

• Not applicable. There is no mention of a "training set" as this is not an AI device being trained.

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

• Not applicable. (See point 8).

In summary, the provided FDA 510(k) summary focuses on demonstrating the substantial equivalence of a medical device (a bronchoscope) through non-clinical testing of its physical, electrical, and reprocessing characteristics. It does not involve AI or diagnostic performance studies that would require the types of acceptance criteria and study details you requested for AI-driven devices.

2. Sample size used for the test set and the data provenance:
The document does not provide any details on a specific "test set" in the context of clinical performance data. The device's substantial equivalence is primarily based on technological comparisons to predicate devices and adherence to recognized standards.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
Not applicable, as no clinical test set with corresponding ground truth established by experts is mentioned.

4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:
Not applicable, as no clinical test set requiring adjudication is mentioned.

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:
Not applicable. This is a submission for an ultrasound system and its software options, not an AI-assisted diagnostic device that would typically undergo MRMC studies to evaluate reader performance improvement with AI. The Virtual Navigator software supports radiological clinical ultrasound but is explicitly stated as "not intended to be used as a standalone diagnostic image."

6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
Not applicable for this type of device and software functionality as described. The Virtual Navigator is an aid to a radiological clinical ultrasound examination, implying human-in-the-loop use, but it does not perform standalone diagnostics.

The EG-3670URK, Ultrasound Video Gastroscope, is intended to provide optical visualization of, ultrasonic visualization of, and therapeutic access to, the Upper Gastrointestinal Track including but not restricted to the organs, tissues, and subsystems: Esophagus, Stomach, Duodenum, Small Bowel, and underlying areas. The instrument is introduced per orally when indications consistent with the requirement for procedure are observed in adult and pediatric patient populations.

Diagnostic Ultrasound imaging or fluid flow analysis of the human body as follows: Endoscopy with Mode of Operation B, M, PWD, Color Doppler, Amplitude Doppler.

PENTAX EG-3670URK Ultrasound Video Gastroscope + HI VISION PREIRUS are the endoscopic ultrasound system consists of an ultrasound endoscope with a radial array type ultrasound transducer, video processor, and Hitachi ultrasound scanner. This modified new system configuration is to work together with the already cleared latest Hitachi HI VISION PREIRUS Diagnostic Ultrasound Scanner (K093466).

The provided document is a 510(k) summary for a medical device modification. It states that the submission is a "Special 510(k)" for a system configuration change, specifically replacing an older ultrasound scanner (Hitachi HI VISION 900) with a newer one (Hitachi HI VISION PREIRUS) while keeping the same PENTAX EG-3670URK Ultrasound Video Gastroscope.

Since this is a Special 510(k) for a modification that does not impact intended use, safety, and/or effectiveness, a detailed clinical study proving device performance against acceptance criteria is generally not required in the same way as a new device submission. Instead, the document focuses on demonstrating substantial equivalence to the predicate device and verification and validation of compatibility.

Therefore, the document does not contain the information requested in your numbered points about acceptance criteria and detailed study results. It primarily focuses on regulatory compliance and the demonstration that the modified system is equivalent to the predicate device.

Here's a breakdown of what can be inferred or directly stated from the document, and what is explicitly missing:

1. Table of acceptance criteria and the reported device performance:

• Missing. The document does not provide a table of acceptance criteria or specific performance metrics for the device. As a Special 510(k) for a system configuration change, the focus is on maintaining existing performance, not establishing new performance.

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):

• Missing. No information on a test set sample size or data provenance is provided.

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

• Missing. No information on experts or ground truth for a test set is provided.

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

• Missing. No information on an adjudication method is provided.

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:

• Missing. This device is an Endoscopic Ultrasound system, not an AI-assisted diagnostic tool. Therefore, an MRMC study or AI-related metrics are not applicable and not mentioned.

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

• Missing. This is not an AI algorithm, but a medical imaging system. Standalone performance as described is not applicable.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

• Missing. No information on ground truth type is provided for a performance study.

8. The sample size for the training set:

• Missing. No information on a training set sample size is provided. This is not an AI/machine learning device.

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

• Missing. No information on how ground truth was established for a training set is provided.

Summary from the document regarding the study and acceptance:

The central 'study' mentioned in this Special 510(k) is the verification and validation (V&V) activities performed to ensure compatibility between the PENTAX EG-3670URK Ultrasound Video Gastroscope and the HITACHI HI VISION PREIRUS Ultrasound Scanner.

• Acceptance Criteria (Implied): The implied acceptance criterion for this submission is that the modified system configuration (Gastroscope + HI VISION PREIRUS) performs "as safe, as effective and substantially equivalent in performance to the above identified cleared predicate device/system" (Gastroscope + HI VISION 900). This is a regulatory acceptance criterion for a Special 510(k), not a clinical performance metric.
• Study/Proof: "The modified system configuration has been verified and validated according to the company's design control activities as certified in this Special 510(K) Submission's declaration of conformity with design control to ensure the compatibility between the PENTAX EG-3670URK Ultrasound Video Gastroscope and the HITACHI HI VISION PREIRUS Ultrasound Scanner."

In essence, for this specific type of submission, the "proof" is the successful execution of design control activities, including verification and validation, demonstrating that the new component (HI VISION PREIRUS) is compatible with the existing device (EG-3670URK) and that the overall system maintains its previous safety and effectiveness. No new clinical performance data is presented because the fundamental performance characteristics are not expected to change, and the change is limited to swapping one compatible component for another.

The EG-3870UTK, Ultrasound Video Gastroscope, is intended to provide optical visualization of, ultrasonic visualization of, and therapeutic access to, the Upper Gastrointestinal Track including but not restricted to the organs, tissues, and subsystems: Esophagus, Stomach, Duodenum, Small Bowel, and underlying areas. The instrument is introduced per orally when indications consistent with the requirement for procedure are observed in adult and pediatric patient populations.

Diagnostic Ultrasound imaging or fluid flow analysis of the human body as follows: Endoscopy

PENTAX EG-3870UTK Ultrasound Video Gastroscope + HI VISION PREIRUS are the endoscopic ultrasound system consists of an ultrasound endoscope with a curved linear array type ultrasound transducer, video processor, and Hitachi ultrasound scanner. This modified new system configuration is to work together with the already cleared latest Hitachi HI VISION PREIRUS Diagnostic Ultrasound Scanner (K093466).

The provided text is a 510(k) summary for a medical device called "PENTAX EG-3870UTK Ultrasound Video Gastroscope (Curved Linear Array Type) + HI VISION PREIRUS". It describes a modification to an already cleared system. This document is a regulatory submission for premarket notification, not a clinical study report detailing acceptance criteria and performance data for a device.

Therefore, I cannot provide the requested information about acceptance criteria and device performance based on the provided text for the following reasons:

• This is a Special 510(k) submission for a modification, not a de novo clearance or a typical 510(k) requiring detailed performance data against acceptance criteria. The submission explicitly states: "There are no software or hardware changes between the PENTAX EG-3870UTK Ultrasound Video Gastroscope subject and predicate device in connecting with the new Hitachi HI VISION PREIRUS Diagnostic Ultrasound Scanner. In addition, there are no change in technology, including features, materials, and principles of operation." The modification is simply a change in the ultrasound scanner used with the endoscope.
• The justification for clearance is "substantial equivalence" to a predicate device, not demonstration of meeting specific performance acceptance criteria through a clinical study. The document states: "The system configuration modification does not impact the intended use, safety and/or effectiveness. The modified system configuration has been verified and validated according to the company's design control activities as certified in this Special 510(K) Submission's declaration of conformity with design control to ensure the compatibility between the PENTAX EG-3870UTK Ultrasound Video Gastroscope and the HITACHI HI VISION PREIRUS Ultrasound Scanner." This implies compatibility testing, not a formal clinical trial with acceptance criteria for diagnostic performance.
• No clinical study to demonstrate "device performance" in terms of sensitivity, specificity, accuracy, etc., is described. The document focuses on the equivalence of the modified system.

In summary, the provided document does not contain the information required to populate the requested table and answer the questions about acceptance criteria, study details, sample sizes, ground truth, experts, or comparative effectiveness studies. This type of information is typically found in full clinical study reports, which are usually not part of a Special 510(k) for a system configuration change like this.
