C. Principles of Operation

a) EG-S100XT
The Endoscope Model EG-S100XT function on the same principles of operation as the predicate device.

This product is lighted by LED at the tip. Its reflection forms an image on CMOS image sensor through a group of object lens placed and set in the tip of this product. An electric signal from CMOS image sensor is transmitted to the processor connected to this product. The processor converts it to a video signal and displays an image on a monitor.

It is possible to do endoscopic fulguration, which enable a user to apply high-frequency electric current to objective regions inserting a high-frequency endotherapy device into the instrument channel of the operating portion. Since there are no exposed metal parts (conductive parts) on the endoscope surface that can be contacted in use, the endoscope can safely perform procedures using high-frequency current.

b) VS-1000
The product controls the light source mounted on the endoscope, receives electrical signals output from the endoscope's image sensor and outputs them as video signals to the display unit after performing image processing such as colour and image quality correction and enhancement.

The display unit's operating console and the endoscope application software built into the display unit are used to manage patient information, adjust white balance, and provide images and patient information to network devices.

Disposable Distal Cap is used with the endoscope and installed to the distal end of endoscope to keep appropriate endoscopic field of view.

Disposable Distal Cap is used with the endoscope and installed to the distal end of endoscope to keep appropriate endoscopic field of view. Disposable Distal Cap is a single structural product, a total of 3 types, and each type is divided into different specifications according to different inner diameter and the diameter of attaching endoscopic distal end. The proposed devices are EO sterilized to achieve the Sterility Assurance Level (SAL) of 10⁻⁶ and placed in a sterility maintenance package to ensure a shelf life of one year.

The provided FDA 510(k) clearance letter and summary for the "Disposable Distal Cap" does not describe an AI medical device. Therefore, the requested information regarding acceptance criteria, study details, human reader performance, AI-specific ground truth, and training set information is not applicable and cannot be extracted from the given document.

The document primarily focuses on demonstrating substantial equivalence to a predicate device (K984358) based on intended use, technological characteristics, and various performance and biocompatibility tests typical for a physical medical accessory. These tests ensure the device's physical and biological safety and performance, not the performance of an AI algorithm.

Below is a breakdown of what can be extracted or inferred from the provided text, but it will not fulfill the requirements for an AI device as those details are absent.

Acceptance Criteria and Device Performance (Non-AI Device)

Since this is not an AI device, there are no AI-specific performance metrics like sensitivity, specificity, AUC, etc. The acceptance criteria revolve around physical and biological attributes. The document states that the proposed device, "Disposable Distal Cap," is substantially equivalent to the predicate device, "Disposable Distal Attachment (K984358)". This substantial equivalence forms the primary "acceptance criterion" for clearance.

Table of Acceptance Criteria and Reported Device Performance (Based on Substantial Equivalence and Performance Data provided for a Non-AI Device):

Information NOT Applicable/Present for an AI Device:

1. Sample size used for the test set and the data provenance: Not an AI device, so no "test set" in the context of AI algorithm evaluation. The testing involved physical device samples.
2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not an AI device. No ground truth established by experts for algorithmic performance.
3. Adjudication method: Not an AI device. No adjudication method for algorithmic output.
4. 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 an AI device. This type of study is irrelevant.
5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not an AI device.
6. The type of ground truth used: Not an AI device. "Ground truth" for this device refers to meeting established engineering and biological safety standards (e.g., passing a cytotoxicity test, maintaining a certain connection force).
7. The sample size for the training set: Not an AI device. No training set.
8. How the ground truth for the training set was established: Not an AI device. No training set.

In summary, the provided document details the regulatory clearance for a physical medical accessory, not an AI medical device. Therefore, the questions specifically related to AI device performance and study design cannot be answered from this text.

The EvoEndo Model LE Gastroscope is intended for the visualization of the upper digestive tract in adults and pediatric patients, specifically for the observation, diagnosis, and endoscopic treatment of the esophagus, stomach, and duodenal bulb. The gastroscope is a sterile single‐use device and can be inserted orally or transnasally.

The EvoEndo Controller is intended for use with an EvoEndo Endoscope for endoscopic diagnosis, treatment, and video observation.

The EvoEndo Endoscopy System is comprised of two regulated components:

• EvoEndo Model LE Single‐Use Gastroscope (hereafter referred to as the EvoEndo Endoscope)
• EvoEndo Controller (hereafter referred to as the Controller)

The EvoEndo Endoscope is a sterile, single‐use gastroscope intended to perform oral or transnasal diagnostic endoscopy in adult and pediatric patients. The EvoEndo Endoscope is ethylene oxide (EO) sterilized and is comprised of:

• Handle
• Umbilical Bundle that includes air, water, and suction lines, as well as the video connector
• Endoscope shaft with HD Camera

The Controller of the EvoEndo Endoscopy System translates the images or video captured by the camera at the distal end of the EvoEndo Endoscope to a monitor via an HDMI cable.

The provided FDA 510(k) clearance letter and summary for the EvoEndo Single-Use Endoscopy System (K250900) do not describe a study involving acceptance criteria for device performance in the context of an AI/human reader study. Instead, this submission focuses on extending the indicated age range for an existing medical device (an endoscope system) and increasing its shelf life.

The "performance testing summary" sections (1.7, 1.8, 1.9, 1.10) refer to:

• Non-clinical functional and performance testing (e.g., visual, dimensional, tip deflection, air/water/suction flow rates, optical performance, electrical safety, EMC). These tests have specific acceptance criteria typical for medical device engineering, but they are not related to AI performance, clinical accuracy, or human reader performance.
• Biocompatibility testing
• Human factors/usability engineering testing
• Literature review to support the age extension. This is a scientific review, not a performance study with acceptance criteria of the type requested in the prompt.

Therefore, I cannot fulfill most of the requested information regarding acceptance criteria and studies typical for AI-enabled medical devices or comparative effectiveness studies with human readers. The document does not contain information about:

• A table of acceptance criteria and reported device performance (in the context of clinical accuracy or AI performance).
• Sample sizes used for a test set (clinical images) or the data provenance.
• Number of experts or their qualifications to establish ground truth for a test set.
• Adjudication methods for a test set.
• Multi-Reader Multi-Case (MRMC) comparative effectiveness study or related effect sizes.
• Standalone (algorithm only) performance.
• Type of ground truth used for clinical validation.
• Sample size for a training set or how its ground truth was established.

The prompt's requirements are designed for AI/imaging analysis devices, which this clearance document does not pertain to. This document is for a physical endoscopy system.

However, I can extract information related to the device and its predicate, as well as the justification for the Indication for Use extension:

Device: EvoEndo Single-Use Endoscopy System
Submission: K250900 (for indication extension and shelf-life extension)
Predicate Device: EvoEndo Single-Use Endoscopy System (K213606)

Summary of Device and Changes:

• Subject Device: EvoEndo Single-Use Endoscopy System (K250900)
  • Components: EvoEndo Model LE Single-Use Gastroscope & EvoEndo Controller
  • Intended Use: Visualization of the upper digestive tract (esophagus, stomach, duodenal bulb) for observation, diagnosis, and endoscopic treatment in adult and pediatric patients (extended from "patients over the age of five years" in predicate). Sterile, single-use, oral or transnasal insertion.
  • Key Differences from Predicate (K213606):
    1. Indicated Age: Removal of "in patients over the age of five years."
    2. Shelf Life: Extended from 6 months to 14 months.
• Predicate Device: EvoEndo Single-Use Endoscopy System (K213606)
  • Intended Use: Same as above, but "in patients over the age of five years."
  • Shelf Life: 6 months.

Acceptance Criteria and "Study" for Indication Extension:

Since this is not an AI-enabled device or a diagnostic device relying on accuracy metrics, the "acceptance criteria" here relate to demonstrating equivalence and safety for the extended indications and shelf life.

Regarding the specific questions in the prompt, based solely on the provided document:

1. A table of acceptance criteria and the reported device performance: As explained above, the "acceptance criteria" for this specific submission relate to the justification for the extended Indication for Use and shelf life, not typical AI/diagnostic performance. The table above attempts to capture this contextually.
2. Sample size used for the test set and the data provenance: Not applicable. No "test set" of clinical images or data was used for a performance validation in this submission type. The justification for age extension was a literature review.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Ground truth for clinical data (like diagnostic accuracy) was not established or presented in this 510(k) for an endoscope.
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: Not applicable. This is not an AI-assisted device.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done: Not applicable. This is not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.): For the current submission, the "ground truth" for the expanded age indication was supported by a clinical literature review and anatomical considerations, along with a risk/benefit evaluation. This is not "ground truth" in the sense of a definitive diagnostic label for performance evaluation.
8. The sample size for the training set: Not applicable. There is no AI training set mentioned.
9. How the ground truth for the training set was established: Not applicable.

In conclusion, the provided FDA document is for the clearance of an endoscope and its extended indications, not an AI-enabled diagnostic device. Therefore, the detailed requirements for AI/diagnostic performance studies cannot be addressed from this document.

FUJIFILM Endoscope Models EG-840T and EG-840TP is intended for the visualization of the upper digestive tract, specifically for the observation, diagnosis, and endoscopic treatment of the esophagus, stomach, and duodenum.

FUJIFILM Endoscope Model EG-840N is intended for the visualization of the upper digestive tract, specifically for the observation, diagnosis, and endoscopic treatment of the esophagus, stomach, and duodenum. This product can be inserted orally or nasally.

Never use this product for any other purposes.

The insertion portion of the device has a mechanism (hereinafter "the bending portion") which bends the tip from right to left and up and down, and a flexible tube (hereinafter "the flexible portion") consists of the bending portion and operating portion with a knob which controls the bending portion. The forceps channel which runs through the operating portion to the tip is arranged inside the insertion portion for inserting the surgical instrument. The insertion portion of the endoscopes comes into contact with the mucosal membrane.

The tip of the insertion portion is called the "Distal end" which contains the Imaging section, Distal cap, Objective lens, Air/water nozzle, Water jet nozzle (Except EG-840N), Instrument channel outlet, and Light guide. The bending portion is controlled by knobs on the control portion/operation section to angulate the distal end to certain angles.

The Flexible portion refers to the long insertion area between the Bending portion and the Control portion (a part of Non-insertion portion). This portion contains light guides (glass fiber bundles), air/water channels, a forceps/suction channel, a CrOS image sensor, and cabling. The glass fiber bundles allow light to travel through the endoscope to illuminate the body cavity, thereby providing enough light to the CMOS image sensor to capture an image and display the image on a monitor. The forceps channel is used to introduce biopsy forceps and other endoscopic accessories, as well as providing suction.

The control portion/operating section provides a grip to grasp the endoscopes and contains mechanical parts to operate the endoscopes. This section includes a Forceps inlet, which allows endoscope accessories to be introduced. The Scope connector connects the endoscopes to the light source.

The provided FDA 510(k) clearance letter pertains to endoscopes, which are hardware devices, not AI/ML software. Therefore, the information requested regarding acceptance criteria, study details, and data provenance for an AI/ML device is not explicitly present in the provided text.

The document focuses on demonstrating substantial equivalence to a predicate device through various non-clinical tests (electrical safety, biocompatibility, endoscope-specific testing, software validation, and reprocessing validation) rather than a clinical effectiveness study involving human readers or AI performance metrics.

However, I can extract information about the device's performance specifications that were tested to prove its general functionality and safety, which can be interpreted as fulfilling certain "acceptance criteria" for a physical medical device.

Here's a breakdown of the available information based on your request, with the caveat that it does not directly address AI/ML performance:

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

The document lists various performance specifications that the device met. It does not provide specific numerical acceptance criteria alongside reported performance values in a table format. Instead, it states that "The subject device met performance specifications in the following additional testing." This implies that the device did meet predefined internal thresholds for these parameters.

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

• Sample Size: Not specified for any of the tests. The document mentions "testing" or "validation activities" without detailing the number of devices or trials involved.
• Data Provenance: Not specified. As this is a 510(k) for a physical medical device (endoscope), the testing would typically be conducted in a laboratory setting by the manufacturer, rather than involving patient data in the context of imaging performance.

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

Not applicable. The tests performed are engineering and safety validations. There is no mention of human expert involvement for establishing "ground truth" in the context of image interpretation or diagnosis, as this is not an AI/ML diagnostic tool.

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

Not applicable. This is a concept typically used in clinical studies involving interpretation by multiple readers, which is not described here.

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 not an AI-assisted device. The document describes a traditional endoscope.

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

Not applicable. The device itself is an endoscope, not an algorithm. Software validation was conducted (IEC 62304:2015), but this relates to the software controlling the endoscope's functions, not a standalone diagnostic AI.

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

For the listed performance specifications (field of view, resolution, etc.), the "ground truth" would be established by objective physical measurements using calibrated equipment and engineering standards. For biocompatibility, it's based on biological response to materials, and for reprocessing, it's based on sterility and decontamination efficacy. There is no "ground truth" in the diagnostic sense as there would be for an AI/ML algorithm.

8. The sample size for the training set

Not applicable. This is not an AI/ML device that requires a training set.

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

Not applicable.

Endoscopic Distal Attachment is intended to be used in combination with compatible endoscopes to maintain the field of view during endoscopic procedures such as mucosal resection.

The Endoscopic Distal Attachment is an additional device, made of TPU designed to attach to the distal end of the endoscope. The device is composed of three main portions: an attaching portion, a distal portion, and a drain portion. The attaching portion is a wider diameter opening which is used to connect the attachment to a compatible endoscope; the distal portion is the ending portion of the attachment which tapers into narrower diameter opening. The hole, which is only available for some models, forms drain portion which prevent the fluids lodging on the surface of the endoscope.

The Endoscopic Distal Attachment can be used in combination with compatible endoscopes to maintain an appropriate endoscopic field of view.

The Endoscopic Distal Attachment has six models, depending on different surface design (flat or incline), with or without hole and with scale or without scale. The models include models of flat face without hole, flat face with hole, inclined face without hole, inclined face with hole, flat face without hole with scale and flat face.

This document is a 510(k) clearance letter for a medical device called "Endoscopic Distal Attachment (AF-D series)". Based on the provided text, the device is not an AI/Software as a Medical Device (SaMD). It is a physical accessory made of TPU that attaches to endoscopes.

Therefore, many of the requested bullet points, such as "MRMC comparative effectiveness study," "standalone (i.e. algorithm only) performance," "sample size for training set," and "how ground truth for training set was established," are not applicable to this type of device and are not discussed in the clearance letter.

The clearance relies heavily on bench testing and biocompatibility data to demonstrate substantial equivalence to a predicate device, rather than clinical study data or AI performance metrics.

Here's an analysis of the provided text in relation to your questions:

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

The document does not present a formal table of acceptance criteria with quantified reported device performance in the precise way you've requested for an AI/SaMD. Instead, it lists the types of performance tests conducted and states that the device "met all design specifications" and "demonstrated safety and essential performance."

The acceptance criteria are implicitly defined by the standards and the comparison to the predicate device. The performance is summarized as meeting these criteria.

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

• Sample Size for Test Set: Not explicitly stated in terms of number of devices or number of tests conducted for each category. The document indicates "performance tests were implemented on both the subject device and the predicate device," implying sufficient samples were used to conduct the various bench tests. This is a physical device, so "test set" would refer to the number of physical devices and components tested.
• Data Provenance: The testing was conducted by Alton (Shanghai) Medical Instruments Co. Ltd. (China). The data origin is from their internal testing. The document implies these are prospective tests conducted specifically for this submission.

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

• N/A. This is a physical non-AI medical device. The "ground truth" for its performance is established through adherence to engineering specifications, material properties, and standardized testing protocols (e.g., ISO, ASTM standards), not through expert consensus on images or clinical outcomes.

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

• N/A. Adjudication methods like 2+1 or 3+1 are typically used for establishing ground truth in clinical imaging studies or pathology where human annotators are involved. For this physical device, performance is evaluated against objective, measurable criteria defined by engineering standards and specifications.

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 a physical device, not an AI/SaMD. MRMC studies are not applicable.

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

• N/A. This is a physical device, not an algorithm.

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

• For this physical device, the "ground truth" (or basis for verification) comes from engineering specifications, material science principles, and international consensus standards (e.g., ISO for biocompatibility and sterilization, ASTM for packaging and mechanical properties). The device's performance is compared against the established limits or requirements of these standards and against the performance of the predicate device.

8. The sample size for the training set

• N/A. This is a physical device, not an AI/SaMD. There is no "training set."

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

• N/A. This is a physical device, not an AI/SaMD. There is no "training set" or corresponding ground truth establishment process in the AI sense.

The Disposable Distal Attachment D-201 Series have been designed to be attached to the distal end of the endoscope to keep the suitable depth of endoscope's view field within the gastrointestinal tract.

The Disposable Distal Attachment D-201 Series is comprised of seven (7), sterile, single-use, distal attachments of varying diameters. Each distal attachment is a short transparent plastic tube which is attached to the distal end of an endoscope to facilitate observation of tissues during endoscopic procedures. A subset of the models includes a drainage side hole that allows egress of water and blood during use. The Disposable Distal Attachment D-201 Series is to be used with compatible endoscopes.

The provided FDA 510(k) clearance letter and summary for the "Disposable Distal Attachment D-201 Series" does not describe a study involving an AI/Medical Imaging device that requires ground truth, human readers, or a test set as described in the prompt.

Instead, this document describes a traditional medical device (a physical accessory for an endoscope) and the performance testing conducted to demonstrate its substantial equivalence to a predicate device. The performance data focuses on biocompatibility, sterilization, packaging, shelf-life, mechanical testing, and human factors. There is no mention of an algorithm, image analysis, or clinical performance in terms of diagnostic accuracy or reader improvement.

Therefore, I cannot fulfill the request to describe the acceptance criteria and the study that proves the device meets the acceptance criteria using the provided information, as the requested elements (ground truth, expert consensus, MRMC studies, training/test sets for an algorithm, etc.) are not applicable to this type of device and its clearance process.

The document states: "Clinical data is not required to demonstrate substantial equivalence." This further confirms that no studies involving analysis of images or AI performance were conducted or necessary for this device's clearance.
