More Information

Not Found

No
The document describes "digital, post-processing imaging enhancement technology" (i-Scan) which is a digital filter-based technique. It does not mention AI or ML.

No.
The device is intended for "diagnosis, treatment and video observation" and specifically states "optical visualization (via a video monitor) of, and, for VNL15-J10 only, therapeutic access to, nasal, pharyngeal and the upper airway anatomy." Therefore, it is considered a therapeutic device.

Yes

The text explicitly states that the PENTAX Medical VIDEO PROCESSOR EPK-3000 is intended for "nasopharyngo-laryngoscopic (ENT) diagnosis."

No

The device is a system that includes both hardware components (video processor, endoscopes, accessories) and software (i-Scan technology). It is not solely software.

Based on the provided information, this device is not an In Vitro Diagnostic (IVD).

Here's why:

  • IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
  • Device Function: The PENTAX Medical EPK-3000 Video Imaging System is used for direct visualization of internal body cavities (nasal, pharyngeal, laryngeal, and upper airway anatomy) using an endoscope and video processing. It does not involve the collection or analysis of specimens outside the body.
  • Intended Use: The intended use clearly states "ENT endoscopic observation and nasopharyngo-laryngoscopic (ENT) diagnosis, treatment and video observation." This describes a procedure performed in vivo (within the living body).
  • Device Description: The description details the components and how they function to illuminate and capture images from within the body. There is no mention of handling or analyzing biological specimens.

While the device is used for diagnosis, the method of diagnosis is through direct visual inspection facilitated by the imaging system, not through the analysis of in vitro samples.

IV. DEVICE DESCRIPTION

PENTAX Medical EPK-3000 Video Imaging System is used for ENT endoscopic observation and nasopharyngo-laryngoscopic (ENT) diagnosis, treatment, and video observation.

The System functions by receiving image signals from the image sensor in an endoscope, which are processed within a processor and then output to a monitor. Brightness, color balance, and other properties of the displayed images can be adjusted using the buttons on the system's control panel. The light from a xenon lamp at the distal end of the endoscope illuminates the body cavities of the patient through the endoscope connected to the video processor.

The primary components of the system include the following:

  • PENTAX Medical Video Processor EPK-3000
  • PENTAX Medical Video Naso-Pharyngo-Laryngoscope VNL-J10 Series (VNL-J10 Series) ●

The PENTAX Medical EPK-3000 Video Imaging System is provided with the following accessories:

  • . Keyboard - input device for the video processor.
  • Foot Switch - used to remotely control processor functions.
  • White Balance Adjuster - used as the object of white balance feature.
  • Condenser Earth Cable - used to reduce high-frequency noise generated during high-frequency electro cautery device use with Pentax endoscopes.
  • . Inlet Seal - prevents suctioned fluid from coming out of the instrument Channel Inlet during the use of suction function. During the reprocessing, it seals the instrument Channel Inlet in order to full 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.

The PENTAX Medical Video Processor EPK-3000 is intended to be used with the PENTAX compatible endoscopes, light sources (including strobe), vide monitors and other ancillary equipment for ENT endoscopic observation and nasopharyngo-laryngoscopic (ENT) diagnosis, treatment, and video observation.

PENTAX Medical Video Processor EPK-3000 functions with the PENTAX i-Scan technology, a digital filter-based image enhancement technique with three modes, i-Scan 1, 2, and 3. PENTAX i-Scan™ is intended to give the user an enhanced view of the texture of the mucosal surface and blood vessels.

White light is captured from a 150-Watt xenon lamp housed in the EPK-3000 Video Processor. All visualization is done with the white light mode first. White light illuminates the tissue and transfers the captured light through the video scope or a charged coupled device (CCD). Note that the white light visualization mode is always used first by the physician. The modification of the combination of red, green, blue (RGB) components for each pixel occurs when the i-Scan function is turned on in the EPK-3000 Video Processor. The resulting i- Scan image is then displayed on the observation monitor.

The PENTAX Medical Video Processor EPK-3000 is compatible with PENTAX Medical Video Naso-Pharyngo-Laryngoscope VNL-J10 Series. The PENTAX Medical Video Naso-Pharyngo-Laryngoscope VNL-J10 Series are intended to be used with a PENTAX Video Processor (including Light source), documentation equipment, video monitor, endoscopic device and other ancillary equipment for optical visualization (via a video monitor) of, and/or therapeutic access to, nasal, pharyngeal, laryngeal and the upper airway anatomy. Three scopes are included in the VNL-J10 Series of scopes that is the subject of this submission: VNL8-J10, VNL11-J10, and VNL15-J10.

The VNL-J10 Series endoscopes are inserted transorally or transnasally to visualize subjects under illumination transmitted from a video processor with a solid-state image sensor located at the distal end of the endoscope, and provide images of the target anatomy on the video monitor. The endoscopes are flexible which allows the insertion portion to shape according to the body cavity. They are also composed of an Insertion Portion, Control Body, PVE Connector, and Light Guide Plug.

The VNL15-J10 can be used with endoscopic devices, each of which is introduced from the instrument channel inlet of the control body. Additionally, suctioning from the instrument channel at the distal end of the endoscope by pressing the suction control valve is available with this model. The VNL8-110 and the VNL11-J10 do not have an instrument channel.
