It is made up of the grip section and insertion tube. It requires connection via USB to a laptop computer, and gains power from the USB ports which supplies 5V of electricity with a maximum current of 0.5A. This is sufficient to power the endoscope. The endoscope does not need an external CCU for image processing, as the processing is done directly on the device on a small chip. It converts the light and color information received by the image sensor into binary numbers (patterns of zeros and ones). The USB Video Class (UVC) driver is a Microsoft-provided AVStream minidriver that provides driver support for USB Video Class devices. When a device uses UVC, it does not need to support their own driver, but instead works automatically with the system-supplied driver. It is compatible to all Windows and Mac computers, with a simple plug and play feature. The visualization from the distal chip is projected onto the computer monitor, at a resolution of 720px1280p high definition. The insertion tube portion of the device is used for visualization within the natural orifices of the mouth and the nasal cavities and in the upper airway anatomy. The light emitted by the LED light source at the distal end of the tip is illuminated into the body cavity of the subject, and the image is displayed onto a screen. The grip section of the device contains a control knob for moving the distal end of the insertion tube bend up or down, up to 130 degrees in either direction. The proximal end of the grip section contains the USB connector, for plug and play with a computer, for power and to provide visualization of the camera chip found at the distal end of the insertion tube. The PatCom Distal Chip Endoscope is substantially equivalent to the Schoelly CMOS Video Nasopharyngoscope, manufactured by Schoelly Fiberoptic GmbH. The Schoelly Nasopharyngoscope has already been approved for the US market since 2014. Similar to the PatCom Distal Chip Endoscope, their nasopharyngoscope also has a grip section, insertion tube section, and a manual knob for angulation of the tip, and are both used for visualization and diagnosis within the nose, mouth and throat. The Schoelly Nasopharyngoscope has been selected as an equivalent device based on a detailed comparison of intended use, technological, imaging and biological characteristics. The intended use of PatCom Distal Chip Endoscope was considered the same as the predicate device, but small differences were identified for structure and technological characteristics. Rationales have been provided to ensure that these differences do not raise any additional safety or performance risks of the PatCom Distal Chip Endoscope compared with equivalent {5}------------------------------------------------ Image /page/5/Picture/0 description: The image shows the logo for Mui Scientific. The logo consists of a circular graphic to the left of the text "Mui Scientific". The graphic is a circle with a dot in the center and five smaller circles around the perimeter.

Data generated from performance studies undertaken has also been used for comparison and to substantiate that it is safe to extrapolate data from equivalent devices. The main difference between the submitted device and the predicate device is the power supply. The distal end of the grip section contains the USB connector, for plug and play with a laptop computer, for power and to provide visualization of the distal chip found at the end of the insertion tube. I It requires connection via USB to a laptop computer, and gains power from the USB ports which supplies 5V of electricity with a maximum current of 0.5A. This is sufficient to power the endoscope. The device does not need an external CCU for image processing, as the processing is done directly on the device on a small chip. It converts the light and color information received by the image sensor into binary numbers (patterns of zeros and ones). The USB Video Class (UVC) driver is a Microsoft-provided AVStream minidriver that provides driver support for USB Video Class devices. When a device uses UVC, it does not need to support their own driver, but instead works automatically with the system-supplied driver. It is compatible to all Windows and Mac computers, with a simple plug and play feature. The visualization from the distal chip is projected onto the computer monitor, at a resolution of 720px1280p high definition. The predicate device, however, requires connection to a control unit for power, which in turn, is powered by connection to a 110V outlet. | | Predicate Device | Subject Device | | |------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-----------------------------------------------------| | Trade name | Schoelly CMOS Video

number | K132009 | K222587 | | | Manufacturer | Schoelly Fiberoptic GmbH | Mui Scientific | | | Indications
For Use | The Schoelly CMOS Video
Nasopharyngoscope System may only
be used by persons with an appropriate
medical qualification and who are
acquainted with the rhino/laryngoscopic
technique. The endoscope is used for
endoscopic diagnosis within the nasal
lumens and airway anatomy, and is
intended to provide visualization via a
video monitor. | The Patcom Distal Chip Endoscope is
indicated when endoscopic
visualization in the regions of mouth,
nasal cavity, and upper airway is
required. | | | Environment
of Use | Healthcare facility/hospital | Healthcare facility/hospital | | | Discussion | In comparing the Indication for Use of the predicate and the proposed device, we
found they are general similar, but utilizing different terminology for the same
physical anatomy structures (lumens/cavity, airway anatomy/upper airway).
According to the description above, the clinical application of the Distal Chip
Endoscope and the equivalent device are essentially identical and does not pose
a significant issue of safety or efficacy. | | | | Technical Specifications | | | | | Power Supply | Endoscope is powered by a 5V d.c., obtained from the USB connection | | | | control unit. The control unit

driver required | Low level of concern; image processing done
on internal chip in endoscope; standard USB
Video Class (UVC) driver | | | Discussion | The biggest difference between the proposed and predicate device exists in
the aspect of power supply. While the predicate device requires power from a
control box that is directly connected to a 110V outlet, the submission device
requires only a small amount of power via USB from a laptop computer. The
electrical safety of the PatCom Distal Chip Endoscope is further supported
by the successful completion of the required electrical testing. For software,
both contain image processing firmware and require a driver to connect
imaging to a monitor. The difference lies in where the image processing
chip is located, and what type of driver is required for the display monitor, of
which the PatCom Distal Chip Endoscope is simpler (with the chip directly
embedded within the endoscope) and easier to use (with the ability to plug
and play and use any standard UVC driver. The other minor differences
noted reflect enhanced features, such as having a wider field of view angle
for better visualization, a smaller insertion tube outside diameter for safer
intubation and patient comfort, and longer working length to allow for
improved maneuverability. Therefore, these minor differences are not
considered to raise different questions of safety and effectiveness compared
to the predicate device. | | | | | Performance
