Intended Use

The PENTAX Medical Video Esophagoscope EE17-J10 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 of esophagus and gastro-esophageal junction.

This endoscope is introduced via the mouth or nose when indications consistent with the need for the procedure are observed in adult and pediatric patient populations.

Device Description

The PENTAX Medical Video Esophagoscope EE17-J10 is intended to be used with a PENTAX Video Processor, video monitor, endoscopic device and other ancillary equipment for optical visualization (via a video monitor) of, and/or therapeutic access to the esophagus and Gastro-Esophageal Junction. This anatomy includes, the following organs, tissues; and subsystems: Esophagus and Gastro-Esophageal Junction.

The EE17-J10 is composed of the following main parts: an insertion portion, control body and PVE connector. The insertion is inserted into the body cavity of patient. The insertion portion includes the distal end and bending section. The objective lens, light guide, instrument channel and air/water nozzle are located on the distal end of the insertion portion. The control body is held by the user's hand. The control body includes the angulation control knob, angulation lock knob/lever, air/water cylinder, suction cylinder, remote button, and instrument channel inlet. The air/water feeding valve is attached to the air/water cylinder, and the suction control valve is attached to the suction cylinder. The inlet seal is attached to the instrument channel inlet. The PVE connected to the video processor via electrical contacts.

The bending section is bent by the angulation control knob to operate the endoscope angulation. The angulation lock knob/lever is used to adjust the rotation torque of the angulation control knob.

The air/water feeding system is used to deliver the air and water to the objective lens from the air/water nozzle. When the hole at the top of air/water feeding valve is covered, the air is delivered. When the air/water feeding valve is pushed, the water is delivered. The suction control system is used to suction the fluid and air in body cavity from the instrument channel. When the suction control valve is pushed, the fluid and air are suctioned.

The remote button is used to operate the functions of the video processor and any external device from the control body, as necessary.

Endoscopic devices such as biopsy forceps are inserted from the instrument channel Inlet into the body cavity through the instrument channel.

The light guide of the distal end is used to illuminate the body cavity by light which is carried through the light carrying bundle. The light carrying bundle guides the light from light guide plug which is connected to the light source inside the Video Processor. The CCD built into the distal end receives reflected light (image data) from the body cavity, and sends the image data to the Video Processor through the video cable. The image data are converted into the image signal by the Video Processor, and the image inside the body cavity is displayed on the monitor.

The PENTAX Medical Video Processors EPK-i7010 and EPK-3000 are compatible with PENTAX Medical Video Esophagoscope EE17-J10.

The PENTAX Medical Video Esophagoscope EE17-J10 is provided with the following accessories:

  • Inlet Seal - prevents suctioned fluid from coming out of the instrument Channel Inlet during the use of suction function. During reprocessing, it seals the instrument Channel Inlet in order to fill the chemical solution inside the channel.
  • Bite Block - prevents patients from biting the endoscope insertion tube during an endoscopic examination.
  • Suction Control Valve - intended to control suction.
  • Air/Water Valve - intended to control air and water feeding.

Additional accessories for reprocessing are provided with the device. These include a Cleaning Adapter, Soaking Cap, Ventilation Cap, Endoscope Cleaning Brush Kits, and replacement O-Rings.

AI/ML Overview

The provided text does not contain detailed acceptance criteria or a comprehensive study report for the device's clinical performance. Instead, it focuses on non-clinical performance data and a brief mention of a "clinical image capture study."

Here's an analysis based on the information available:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not provide a table specifying distinct acceptance criteria for clinical performance and corresponding reported device performance metrics. It mainly lists validation studies for non-clinical aspects and states that "All acceptance criteria were satisfied" for reprocessing validation.

For the "Optical Performance" and "Clinical Image Capture Study," it claims equivalence or demonstration of capability rather than specific quantitative performance against acceptance criteria.

2. Sample Size Used for the Test Set and Data Provenance

  • Clinical Image Capture Study: The document states that "A clinical image capture study was performed," but it does not specify the sample size (e.g., number of patients or cases) used for this test set nor the data provenance (e.g., country of origin, retrospective or prospective nature).

3. Number of Experts and Qualifications for Ground Truth

  • The document does not mention the number of experts used to establish ground truth for the clinical image capture study, nor their qualifications.

4. Adjudication Method

  • The document does not specify any adjudication method used for the clinical image capture study's ground truth.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

  • No information is provided about a multi-reader multi-case (MRMC) comparative effectiveness study. The document does not discuss human reader improvement with or without AI assistance, as the device described is an esophagoscope and not an AI-powered diagnostic tool in the typical sense that would involve such a study.

6. Standalone (Algorithm Only) Performance

  • This question is not applicable as the device is an esophagoscope, a medical instrument for direct visualization, not an algorithm for standalone diagnostic performance.

7. Type of Ground Truth Used

  • For the "Clinical Image Capture Study," the document states it was performed "to demonstrate the maneuverability of the EE17-J10 endoscope and its ability to capture images at each of the pre-determined anatomical areas when used in a clinical setting." This suggests the ground truth was based on the successful visualization and image capture of anatomical areas by a clinician, rather than expert consensus on a diagnosis, pathology, or outcomes data.

8. Sample Size for the Training Set

  • This question is not applicable as the device is an esophagoscope and does not appear to involve a "training set" in the context of machine learning or AI algorithms. The "reference device" EG17-J10 (K210177) is used for comparison in performance, not as a training set for the current device's development.

9. How Ground Truth for the Training Set Was Established

  • This question is not applicable for the same reason as point 8; there is no mention of a "training set" with established ground truth for this medical device's clearance.

In summary, the provided text details non-clinical performance evaluations (reprocessing, biocompatibility, software/cybersecurity, electrical safety, system performance, optical performance) focused on establishing substantial equivalence to a predicate and reference device. However, it lacks specific details regarding quantitative clinical performance, acceptance criteria, sample sizes, expert involvement, or ground truth establishment for a clinical study that would directly address device effectiveness in a diagnostic or therapeutic context. The "Clinical Image Capture Study" is mentioned as merely demonstrating the device's ability to capture images in clinical settings.

therapeutic procedures in the esophagus and gastro-esophageal junction, however the predicate models (11301BN1and 11302BD1) cover additional ENT areas like nasal sinuses and larynx.

As to the design differences, The Karl Storz Trans-Nasal Esophagoscopes are manually operated surgical devices, that utilize fiber-optic technology. Whereas EE17-J10 utilizes the latest HD quality white light imaging combined with two forms of image enhancement technologies: i-SCAN and OE. To compare old fiber optic technology to the latest HD quality is not appropriate due to the modern technological advancements in the latter category that lead to superior image quality. Instead, PENTAX Medical will be using a cleared reference device EG17-J10 (K210177) with similar technology for performance characteristics comparison and substantial equivalence establishment between EE17-J10 and EG17-J10.

Image /page/6/Picture/2 description: The image contains the logo for Pentax Medical. The word "PENTAX" is in red, bold, uppercase letters. Below the word "PENTAX" is a gray line. Below the gray line is the word "MEDICAL" in gray, bold, uppercase letters.

Esophagoscopes are intended for illuminating and viewing the inside of the human body. The patient contacting components of both the subject and predicate devices are biocompatible. Both subject and the predicate scopes are reprocessed by the user. The changes in the subject device raise no issue of safety and effectiveness of the device as these differences have no effect on the performance function or general intended use of the device.

Since the predicate and subject devices utilize different technologies, the substantial equivalence will be evaluated through performance testing and comparison to the reference device PENTAX Medical Video Upper Gl Scope EG17-J10 (K210177) which share the same design as EE17-J10.

The components of the PENTAX Medical Video Esophagoscope EE17-J10 have the same fundamental technology and operating principles as the reference device (EG17-J10).

  • A video processor
  • Video Upper GI Scopes to provide optical visualization of (via a video monitor), and therapeutic access to the Upper Gastrointestinal Tract.
  • Accessories, including but not limited to a keyboard, foot switch, White Balance Adjuster, and Condenser Earth Cable

The only design difference between subject and reference devices is in the Scope working length (has a shorter working length for EE17-J10). Therefore, the subject device is identical or enhanced to the reference device with regard to

  • Direction of view
  • Field of view
  • Depth of field
  • Tip angulation
  • Rigid distal width
  • Insertion tube width
  • Maximum insertion portion width
  • Maximum instrument channel width
  • Software

  • viii. Clinical Image Capture Study
    A clinical image capture study was performed to demonstrate the maneuverability of the EE17-J10 endoscope and its ability to capture images at each of the pre-determined anatomical areas when used in a clinical setting.

Substantial Equivalence Discussion:

After analyzing the intended use, indications for use, technological characteristics (including fundamental operating principle, energy source, scientific technology, functional characteristics, design features, performance characteristics, and constituent materials), labeling, and sterilization method, PENTAX Medical concludes that the subject device PENTAX Medical Video Esophagoscope EE17-J10 is as safe and effective as the predicate device. The Intended Uses of the subject and predicate devices are similar, except for nasal sinuses and larynx that are excluded from the subject device and are therefore, substantially equivalent. The technological differences in terms of design features, performance characteristics and constituent materials are not substantive.

8 CONCLUSION

Accordingly, PENTAX Medical believes the PENTAX Medical Video Esophagoscope EE17-J10 is substantially equivalent to the identified predicate, Karl Storz Trans-Nasal Esophagoscope models 11301BN1and 11302BD1 (K051972). Due to technological obsolesce of the predicate device, the design and technological characteristics of the subject EE17-J10 is compared to those of the reference device EG17-J10 (K210177). EE17-J10 and EG17-J10 are substantially equivalent in terms of endoscopic design, specifications and optical performance
