The document describes a standard endoscope system and accessories with no mention of AI, ML, or advanced image processing capabilities. The performance studies focus on sterility, biocompatibility, and endoscope compatibility, not algorithmic performance.
Yes
The Endoscope EN-580T's intended use explicitly states "endoscopic treatment." This indicates that it is not solely for diagnosis but also for performing medical interventions within the digestive tract, thus qualifying it as a therapeutic device.
Yes
The Endoscope EN-580T's "Intended Use / Indications for Use" explicitly states that it is intended for "observation, diagnosis, and endoscopic treatment."
No
The device description clearly details physical hardware components including an endoscope, over-tube, balloon, and tube kit, all of which are physical medical devices. There is no mention of software as the primary or sole component.
Based on the provided information, this device is NOT an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states the device is for the visualization, diagnosis, and endoscopic treatment of the digestive tract. This involves direct interaction with the patient's body for observation and intervention.
- Device Description: The description details the physical components and how they are used within the patient's body (inserted perorally and transanally, assisting with movement inside the digestive tract, stabilizing the endoscope).
- Lack of In Vitro Activity: There is no mention of the device being used to examine specimens outside of the body, such as blood, tissue, or other bodily fluids. IVDs are specifically designed for testing these types of samples in a laboratory or clinical setting.
- Focus on Visualization and Treatment: The primary functions described are visualization (seeing inside the body) and facilitating endoscopic treatment (inserting surgical instruments). These are not typical functions of an IVD.
In summary, the device is an endoscopic system used for direct examination and treatment within the patient's body, which falls under the category of a medical device, but not an In Vitro Diagnostic device.

Device Description
The endoscope EN-580T is inserted both perorally and transanally into the gastrointestinal tract during clinical use. The insertion of the device has a mechanism which bends the tip from right to left and up and down, and a flexible tube consists of the bending portion and operating portion with a knob which controls the bending portion. The forceps channel which runs through the operating portion to the tip is arranged inside the insertion portion for inserting the surgical instrument.
The over-tube TS-1314B is introduced in the patient's anatomy with the pairing endoscope. TS-1314B is assembled over the outer diameter of endoscope. The endoscope and the over-tube are not advanced both at the same time, but alternatingly and successively. TS-1314B is provided sterile and single-patient use only.
The balloon BS-4 is attached to the balloon-compatible endoscope. The balloon air feed outlet should be contained inside BS-4. The accompanying fixing rubber is used to affix the scope balloon in place. The fixing rubbers are made specifically for BS-4 but should not be mixed with the fixing rubber of other scope balloons. BS-4 is provided sterile and single-patient use only.
The tube kit TY-500D consists of a set of two tubes connects the over-tube to the balloon controller by its air inlet. The other tube connects the same balloon controller to the endoscope by its balloon air feed inlet. TY-500D is only compatible with PB-30, cleared K153483. TY-500D is provided non-sterile. The tubes are not patient-contacting and reusable, but each filter is single-patient use only.

Summary of Performance Studies
Sterility of TS-1314B and BS-4 were evaluated using the following consensus standards: ISO 11135:2014. ISO 10993-7:2008/AMD1:2019, ISO 11607-1:2019, ISO 11607-2:2019, ISO 11737-1:2018, and ISO 11138-1:2017.
The new accessories are made of different materials compared to the respective predicate devices. Biocompatibility of each new accessory was evaluated using the following consensus standards: ISO 10993-1:2018, ISO 10993-5:2009, ISO 10993-10:2010, and ISO 10993-12:2012. Biocompatibility testing was performed in accordance with FDA's guidance, Use of International Standard ISO 10993-1, 'Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process', issued September 4, 2020.
Endoscope specific testing was conducted according to ISO 8600-1:2015. ISO 8600-3:2019, and ISO 8600-4:2014. Endoscope compatibility with the new accessories was conducted with acceptable results.

Performance Data:
Sterility of TS-1314B and BS-4 were evaluated using the following consensus standards: ISO 11135:2014. ISO 10993-7:2008/AMD1:2019, ISO 11607-1:2019, ISO 11607-2:2019, ISO 11737-1:2018, and ISO 11138-1:2017.
The new accessories are made of different materials compared to the respective predicate devices. Biocompatibility of each new accessory was evaluated using the following consensus standards: ISO 10993-1:2018, ISO 10993-5:2009, ISO 10993-10:2010, and ISO 10993-12:2012. Biocompatibility testing was performed in accordance with FDA's guidance, Use of International Standard ISO 10993-1, 'Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process', issued September 4, 2020.
Endoscope specific testing was conducted according to ISO 8600-1:2015. ISO 8600-3:2019, and ISO 8600-4:2014. Endoscope compatibility with the new accessories was conducted with acceptable results.
Conclusions:
The proposed devices Endoscope EN-580T, Over-tube TS-13140, Balloon BS-3, and Tube Kit TY-06D shares the same intended use as the respective predicate devices. The endoscope's compatibility with the new accessories was evaluated. The differences among the accessories and their respective predicate devices have been evaluated for the biocompatibility and bench testing with acceptable results. Thus, the proposed device Endoscope EN-580T, Over-tube TS-13140, Balloon BS-3, and Tube Kit TY-06D are substantially equivalent to the respective predicate devices, FUJIFILM Double Balloon Endoscope EN-580T (K183683), Over-tube TS-13140 (K143556), Balloon BS-3 (K213195), and Tube Kit TY-06D (K143556).
