No
The document explicitly states "Mentions AI, DNN, or ML: Not Found" and the description of the device and its function does not mention any AI/ML components. The "Suspected GI Bleeding Indicator (SGIB)" is mentioned, but the description does not indicate it uses AI/ML for this function.
No
The device is intended for visualization and monitoring purposes, not for providing therapy or treatment. Its function is diagnostic, helping physicians detect abnormalities.
Yes
Explanation: The device is intended for "visualization of the small bowel mucosa" to "monitor lesions" that may indicate various conditions, and it is used as a "tool in the detection of abnormalities." Post-procedure, a physician "reviews the patient image data for suspected abnormalities." This process of identifying and evaluating potential medical conditions through visualization directly aligns with the definition of a diagnostic device.
No
The device description explicitly lists hardware components (MiroCam® Capsule, MiroCam® Receiver, Data Cable / Data Belt) in addition to the software (MiroView™ Software).
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information about a person's health. This testing is done outside of the body (in vitro).
- MiroCam System Function: The MiroCam system works by capturing images inside the patient's body (in vivo) as the capsule travels through the small bowel. It visualizes the mucosa directly.
- Intended Use: The intended use is for visualization and monitoring of lesions, not for analyzing specimens taken from the body.
- Device Description: The description clearly outlines a system for capturing and transmitting images from within the GI tract.
While the system provides diagnostic information, it does so through direct visualization within the body, not through in vitro testing of specimens.

Device Description
The MiroCam® Capsule Endoscope System is comprised of the following core components:
-MiroCam® Capsule: MC2000-B
- MiroCam® Receiver: MR2000 -
- Data Cable / Data Belt (Optional): MR1000-D / MR1000-D(S) or MR1000-D(M) or MR1000-D(L)
- MiroView™ Software: MiroView™ U 4.0 -
The general usage workflow of the MiroCam® system is as follows, the MiroCam® capsule captures images of the GI tract, which are sent via Human Body Communication to sensor pads which are affixed to the patient body. The sensor pads are connected to the receiver by the data cables. The image data is stored on the receiver for the duration of the patient procedure. After removing the receiver set from the patient body, the receiver is connected via USB to the Commercial PC and the image data is uploaded. Following upload, the physician (Gastroenterologist) reviews the patient image data for suspected abnormalities of the small bowel.
Mentions image processing
- Functionally, the MiroCam® captures imaging via a CMOS imaging sensor for at least 12 hours at the rate of 6 images per second.
- The MiroView™ U 4.0 helps the user to upload the image data from the Receiver and review the image data with displaying.
- MiroView™ Client has functionalities: List Mode (Case Data Management), Review Mode (Video Display, Image Capture, Annotation Box, etc.), Report Mode (User Comment, Auto Disease Name Check, etc), Export Mode (JPG, AVI, MiroVlew™ file format)
- The Suspected GI Bleeding Indicator (SGIB) is intended to mark frames of the video suspected of containing blood or red areas.
- For the MC1200-B, Auto Exposure time is used to adjust the LED turn-on time depending on the target brightness, which applies equally to the MC2000-B.
- Depending on the sensor's incident light intensity, the AE function optimally adjusts the exposure time, thus preventing the over-exposure and low exposure situations. Namely, it calculates an average brightness of the image and, after checking the present state of the exposure, adjusts the exposure doze to make sure that the current average brightness converges to target brightness value by means of P-control. ASPIN adjusts the exposure time by adjusting the pixel control timing as well as LED ON-time. The unit step of exposure time adjustment is 1 PCLOCK period.

- MiroView™ Software: MiroView™ U 4.0 -
The general usage workflow of the MiroCam® system is as follows, the MiroCam® capsule captures images of the GI tract, which are sent via Human Body Communication to sensor pads which are affixed to the patient body. The sensor pads are connected to the receiver by the data cables. The image data is stored on the receiver for the duration of the patient procedure. After removing the receiver set from the patient body, the receiver is connected via USB to the Commercial PC and the image data is uploaded. Following upload, the physician (Gastroenterologist) reviews the patient image data for suspected abnormalities of the small bowel. The key system components are explained in detail below.
MiroCam® Capsule
Functionally, the MiroCam® captures imaging via a CMOS imaging sensor for at least 12 hours at the rate of 6 images per second. Twelve white LEDs flash in concert with the imaging sensor. A sensor PCB links the imaging sensor to the two gold electrodes of the capsule, from which a weak current is emitted containing the image data via Human Body Communication technology. The weak current is then passed through the bodily tissue and fluid to be picked up by the sensor pads. Human Body Communications is uni-directional from the capsule to the sensor pads.
Physically, the capsule is 30.1mm in length, and 10.8mm in diameter. The exterior of the capsule is composed of biocompatible materials, capable of withstanding potential bite forces and exposure to fluids in the GI tract.
MiroCam® Receiver
The image data from the capsule is saved to the MiroCam® Receiver via the sensor pads and data cables. The sensor pads are standard ECG type sensor pads (3M Red Dot), which are affixed to the patient's abdomen according to the location guide. The 9 sensor pads are attached to the 9 leads of the data cable, and the data cable is subsequently attached to the Receiver sits in a shoulder pouch, which is put on the patient for the duration of the procedure. A waist pouch is used to organize the data cables.
5
The Receiver can store images for up to 12 hours. Using LCD display it shows icons that indicate the state of receiver, real time image view and preview. User can capture image for the real time images are displayed. Three LEDs also represent the receiver state by switching its power. And MiroCam® receiver play some sounds for notifying to user. To reduce the battery consumption of MiroCam® receiver backlight brightness is controlled. User can control MiroCam® receiver by using three buttons.
The dimensions of the receiver are 145mm in height, 82.5mm in width, and 29.8mm in length. The units weight 330 grams, which is data cable. The battery is lithium ion, and is unique to the Receiver. The battery is rechargeable, and can be charged by placing in the battery charger provided with the Receiver. The receiver uses a storage flash for storing the images.
MiroView™ U 4.0
The MiroView™ U 4.0 helps the user to upload the image data from the Receiver and review the image data with displaying.
MiroView™ U 4.0 will be deployed as three types of software: MiroView™M Server, MiroView™M Operator and MiroView™ Client.

For the predicate device and the subject device, this has all the same performances except Receiver and Software.
[Capsule]
Subject device uses the same optical system as Capsule of Predicate device K143663. It means that this optical system uses the same parts as those of K143663 such as Sensor, LED, and Lens. However, the K143663 Capsule can only shoot in one direction, but the subject device can shoot in both directions. Two-way Capsule has the advantage of eliminating blind spots by two-way shooting because it has two identical optical systems compared to one-way Capsule. This is comparable to that of the Predicate device in terms of effectiveness. And this two-way Capsule endoscope system has the reference device, COLON 2, K123666. The COLON 2 is able to expand indications for use from diagnosis of colon to diagnosis of small bowel due to the advantages of bi-directional photography and increased frame number. The frame number of this submitted the subject device is smaller than that of the reference device and because it cannot prove the effectiveness of colon diagnosis, the reference device is limited to small bowel diagnosis. In addition, the subject device is smaller in size than the COLON 2 of the
10
reference device K123666, which makes ease of ingestion easier.
And because two optical systems are used compared to K143663, Operating Time and Shelf Life can be different, and it is proved that there is no problem in operating time when using within the given period through Performance and Bench Test.
- . Ease of device ingestion
The size of MC2000-B is 30.1mm x Ø10.8mm. This is smaller than the 31.5mm x Ø11.6mm of the previously FDA clearance device COLON 2 (K123666). So ease of device ingestion of subject device is smaller than COLON 2 (K123666) and can be claimed to be easier to ingest.
The predicate device K143663 and the subject device are using the same sensor (ASPIN), LED and battery. However, the subject device has two image sensors in each head of the capsule and two sensors capture images alternately, so that the total current can be minimized. (See "Hand Shaking Mode for
Dual camera")
Hand Shaking Mode for Dual camera
ASPIN supports dual camera mode. One of the two chips is set to operate in Master mode by setting the SEL SAVE pin to "LOW" while another chip must be set to operate in Slave mode by setting the SEL SLAVE pin to "High". In Dual mode, the hand shaking operation is implemented using HAND1 pins. In Master mode, HAND0 operates as output and HAND1 operates as input. In slave mode the situation is opposite. Timing diagram is shown below.

Image /page/11/Figure/1 description: The image shows a timing diagram with several signals, including HAND0, HAND1, SCL, SDA, LED0, SEL_SLAVE, TX, and pd. The diagram is divided into two sections, labeled "Master" and "Slave", each with its own set of signals. The HAND0 signal has numbered sections 1 through 8. The diagram illustrates the timing relationships between these signals in a master-slave communication scenario.

Changing of battery voltage caused by LED connected with control resistance than entire battery voltage changes due to increase of LED resistance has no affect on image quality.
Image /page/11/Figure/4 description: The image shows two different LED module schematics. The first schematic is labeled "LED Module of MC1200-B" and shows a module with two current control resistors labeled R1 and R2, each with a value of 100. The second schematic is labeled "LED Module of MC2000-B" and shows two modules labeled "Master" and "Slave", each with two current control resistors labeled R2 and R3, each with a value of 150.
Figure 12-2_Comparison LED Module
For the MC1200-B, Auto Exposure time is used to adjust the LED turn-on time depending on the target brightness, which applies equally to the MC2000-B.

AE (Auto Expose Control)
Depending on the sensor's incident light intensity, the AE function optimally adjusts the exposure time, thus preventing the over-exposure and low exposure situations. Namely, it calculates an average brightness of the image and, after checking the present state of the exposure, adjusts the exposure doze to make sure that the current average brightness converges to target brightness value by means of P-control. ASPIN adjusts the exposure time by adjusting the pixel control timing as well as LED ON-time. The unit step of exposure time adjustment is 1 PCLOCK period.
[Receiver]
The Human Body Communication (HBC) method is used on both Subject device and Predicate device (K143663). Even if. Subject device and Predicate device share same communication method, they have different way to display real time view (RTV). Predicate device displays RTV using another device such as laptop and tablet PC via USB or wifi connection, abd Subject device displays these RTV on LCD on the receiver, similar way to Predicate device (K123864).
Another difference, electro-mechanically can be found between K143663 and Subject device but we conducted Safety and EMC test to verifie both devices are safe.
