No
The description focuses on standard electrosurgical generator and forceps technology, with no mention of AI or ML capabilities. The GUI is described as a standard interface for controlling settings, not for intelligent processing.
Yes
The device is described as an "electrosurgical generator" and "PK Cutting Forceps" intended for "cutting and coagulation of tissue," "electrosurgical coagulation, mechanical cutting, and grasping of tissue" during surgical procedures, which are therapeutic actions.
No
The device is an electrosurgical generator and cutting forceps, intended for cutting and coagulation of tissue, not for diagnosing conditions.
No
The device description clearly states that the ESG-410 is a "reusable, non-sterile electrosurgical generator" and the PK Cutting Forceps are a "bipolar electrosurgical device." These are hardware components that perform the primary function of the medical device (cutting and coagulation of tissue). While the generator has a touch screen GUI and software for control and settings, the core functionality is delivered through the hardware.
Based on the provided text, neither the ESG-410 electrosurgical generator nor the PK Cutting Forceps are IVD (In Vitro Diagnostic) devices.
Here's why:
- Intended Use: The intended use for both devices is for cutting and coagulation of tissue within the body during surgical procedures (open, laparoscopic, and endoscopic). IVD devices are intended for the examination of specimens derived from the human body in vitro (outside the body) to provide information for diagnostic, monitoring, or compatibility purposes.
- Device Description: The descriptions detail devices used for applying electrical energy directly to tissue for surgical purposes. This is not the function of an IVD device.
- Lack of IVD Characteristics: The text does not mention any of the typical characteristics of an IVD device, such as:
- Analyzing biological samples (blood, urine, tissue samples, etc.)
- Reagents or assays
- Providing diagnostic information based on laboratory analysis
Therefore, these devices are not IVD devices. They are electrosurgical devices used for therapeutic purposes during surgery.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Performance Testing Bench:
ESG-410 Electrosurgical Generator
To demonstrate substantial equivalence following aspects were considered within the validation versus the predicate devices.
- Performance and validation tests incorporated the same range of waveform outputs and power levels.
- During the validation testing the waveforms and tissue effects were compared directly between the subjected and predicate device and between the subject and reference devices.
Bench testing supports the claim of substantial equivalence to the predicate devices. The validation plan specifies modes, instruments and test protocols/plans for tissue effects and electrical waveforms. Beside tissue effects, the waveforms of the generators were compared. For all modes the tests demonstrated comparable tissue effects and electrically comparable waveforms.
The following non-clinical and preclinical tests were conducted:
- non-clinical (electrical, dimensional, functional, stability)
- preclinical (simulated use) evaluation and testing of tissue effects and thermal safety
Non-clinical: Basic safety and performance testing was performed in accordance with IEC standards. In addition, verification and comparison bench studies were conducted to evaluate the functional performance.
Preclinical: Evidence obtained from preclinical simulated use studies demonstrate that the device performs substantially equivalent to the predicate device in relevant aspects associated with usability, tissue effects, and thermal effects. For simulated use testing, three clinically relevant tissue types were evaluated in all applicable modes. The tissue effects testing included quantitative and qualitative assessment.
These comprehensive validation bench tests support equivalence to the predicate device. Testing confirmed that comparable tissue effects could be achieved for applicable modes of operation with three tissue types.
Usability and user interface was also assessed according to the risk management plan. The assessment was based on Olympus predecessor product. Use-related hazardous situations were assessed and risk mitigation measures in terms of usability design for safety were defined. The residual risk was evaluated as acceptable.
Risk analysis was carried out in accordance with established internal acceptance criteria based on ISO 14971:2007.
PK Cutting Forceps ( PK-CF0533)
Basic compatibility testing was conducted to confirm compatibility of the legacy PK Cutting Forceps with the subject ESG-410 generator. "ACTIVE ACCESSORY HF Dielectric Strength" testing per IEC 60601-2-2:2017 Ed.6, Clause 201.8.8.3.103 and "Maximum Temperature During Normal Use" testing per IEC 60601-2-2:2017 Ed.6, Clause 201.11.1.1 were repeated for the PK Cutting Forceps with the ESG-410 generator as part of the basic compatibility testing to demonstrate compatibility with the new generator.
Conclusion:
The performance data support the safety of the devices and demonstrate that the subject devices comply with the recognized standards as specified.
In summary, we believe the ESG-410 and accessories are substantially equivalent with the predicate devices with respect to the general design approach, function, and the intended use. The subject ESG-410 and the compatibility of the PK Cutting Forceps with the subject ESG-410, raise no new concerns of safety or effectiveness when compared to the predicate and the reference devices.

The validation plan specifies modes, instruments and test protocols/plans for tissue effects and electrical waveforms. Beside tissue effects, the waveforms of the generators were compared. For all modes the tests demonstrated comparable tissue effects and electrically comparable waveforms.
The following non-clinical and preclinical tests were conducted:
-
- non-clinical (electrical, dimensional, functional, stability)
-
- preclinical (simulated use) evaluation and testing of tissue effects and thermal safety
Non-clinical: Basic safety and performance testing was performed in accordance with IEC standards. In addition, verification and comparison bench studies were conducted to evaluate the functional performance.
Preclinical: Evidence obtained from preclinical simulated use studies demonstrate that the device performs substantially equivalent to the predicate device in relevant aspects associated with usability, tissue effects, and thermal effects. For simulated use testing, three clinically relevant tissue types were evaluated in all applicable modes. The tissue effects testing included quantitative and qualitative assessment.
These comprehensive validation bench tests support equivalence to the predicate device. Testing confirmed that comparable tissue effects could be achieved for applicable modes of operation with three tissue types.

Usability and user interface was also assessed according to the risk management plan. The assessment was based on Olympus predecessor product. Use-related hazardous situations were assessed and risk mitigation measures in terms of usability design for safety were defined. The residual risk was evaluated as acceptable.
Risk analysis was carried out in accordance with established internal acceptance criteria based on ISO 14971:2007.
PK Cutting Forceps ( PK-CF0533)
Basic compatibility testing was conducted to confirm compatibility of the legacy PK Cutting Forceps with the subject ESG-410 generator. "ACTIVE ACCESSORY HF Dielectric Strength" testing per IEC 60601-2-2:2017 Ed.6, Clause 201.8.8.3.103 and "Maximum Temperature During Normal Use" testing per IEC 60601-2-2:2017 Ed.6, Clause 201.11.1.1 were repeated for the PK Cutting Forceps with the ESG-410 generator as part of the basic compatibility testing to demonstrate compatibility with the new generator.
2.8.7 Reprocessing
Required cleaning, disinfecting and drying procedures are described in the instructions for use.
The PK Cutting Forceps are provided sterile, for single-use. They are not intended to be reprocessed.

2.9 Conclusion
The performance data support the safety of the devices and demonstrate that the subject devices comply with the recognized standards as specified.
In summary, we believe the ESG-410 and accessories are substantially equivalent with the predicate devices with respect to the general design approach, function, and the intended use. The subject ESG-410 and the compatibility of the PK Cutting Forceps with the subject ESG-410, raise no new concerns of safety or effectiveness when compared to the predicate and the reference devices.
