AI/ML Overview

This 510(k) submission does not contain information about a study that proves the device meets specific acceptance criteria in the way described in the prompt. This document focuses on demonstrating substantial equivalence to a predicate device rather than presenting a performance study with detailed acceptance criteria and results.

Here's a breakdown of the requested information based on the provided text, highlighting what is not available:

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

Acceptance Criteria	Reported Device Performance
Not explicitly stated in terms of quantitative performance metrics. The submission states the device "has the same device characteristics as the predicate device" and "conforms to IEC 60601-1, IEC 60601-2-18, and IEC 60601-1-2" (safety standards).	"Substantially equivalent" to the predicate device in areas of design, indication for use, technological characteristics, function, application, safety, and effectiveness. Conformity to: Biocompatibility (ISO 10993-1)Medical electrical equipment safety (IEC 60601-1)Specific safety for endoscopic equipment (IEC 60601-2-18)Electromagnetic compatibility (IEC 60601-1-2)

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

Not applicable. No specific performance study with a test set is described in relation to clinical or diagnostic performance. The testing mentioned (biocompatibility, safety, EMC) would involve material samples or electrical measurements, not a patient test set for diagnostic accuracy.

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

Not applicable. No such clinical or diagnostic performance study is described.

4. Adjudication method for the test set:

Not applicable. No such clinical or diagnostic performance study is described.

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

No, an MRMC comparative effectiveness study was not done. The device is an esophagoscope system, not an AI-assisted diagnostic tool.

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

Not applicable. This is a medical imaging device, not an algorithm being evaluated in isolation for diagnostic performance. Its function is to capture images for human interpretation.

7. The type of ground truth used:

Not applicable. Since no diagnostic performance study is presented, there is no mention of ground truth established through expert consensus, pathology, or outcomes data. The "ground truth" for the device's claims are its stated technical characteristics and adherence to safety and performance standards, proven through physical testing rather than clinical study.

8. The sample size for the training set:

Not applicable. This submission is for an imaging system, not a machine learning or AI algorithm that would require 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 involved.

Summary of what the document does provide:

The document focuses on establishing substantial equivalence to an existing legally marketed device (the E.G. Scan™ Esophagoscope System, K111030, and Vision-Science, Inc.'s Modified Flexible Trans-Nasal Esophagoscope, K072088). This is a common pathway for 510(k) clearances, where extensive new clinical performance data is often not required if the new device is technologically similar and has the same indications for use as a predicate.

The main evidence provided for safety and effectiveness is:

Comparison to predicate device: Stating "The E.G. Scan™ II Esophagoscope System and predicate device are substantially equivalent in the areas of design, indication for use, technological characteristics, function, application and safety and effectiveness."
Compliance with recognized standards:
- Biocompatibility (ISO 10993-1)
- Medical electric equipment safety (IEC 60601-1)
- Specific safety for endoscopic equipment (IEC 60601-2-18)
- Electromagnetic compatibility (IEC 60601-1-2)

Therefore, the "acceptance criteria" here are primarily framed as compliance with these standards and demonstrated substantial equivalence, rather than specific quantitative performance metrics from a clinical diagnostic study.

Dear Mr. Mouser:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must

§ 874.4710 Esophagoscope (flexible or rigid) and accessories.

(a)
Identification. An esophagoscope (flexible or rigid) and accessories is a tubular endoscopic device with any of a group of accessory devices which attach to the esophagoscope and is intended to examine or treat esophageal malfunction symptoms, esophageal or mediastinal disease, or to remove foreign bodies from the esophagus. When inserted, the device extends from the area of the hypopharynx to the stomach. It is typically used with a fiberoptic light source and carrier to provide illumination. The device is made of materials such as stainless steel or flexible plastic. This generic type of device includes the flexible foreign body claw, flexible biopsy forceps, rigid biopsy curette, flexible biopsy brush, rigid biopsy forceps and flexible biopsy curette, but excludes the fiberoptic light source and carrier.(b)
Classification. Class II.
