Yes.
The device is intended for "cutting and coagulation of tissue in open surgery, laparoscopic surgery and endoscopic surgery," which are therapeutic applications.
No
The device is an electrosurgical generator intended for cutting and coagulation of tissue. Its function is to perform surgical procedures, not to diagnose medical conditions.
No
The device description clearly states it is a reusable, non-sterile electrosurgical generator with physical components like a touch screen GUI, sockets, and a power switch. It also includes accessories like an argon plasma coagulation unit and probes, which are hardware. The performance studies involve bench testing of waveforms, tissue effects, and electrical characteristics, further indicating a hardware-based device.
Based on the provided information, the ESG-300 electrosurgical generator and its accessories (APU-300, Pressure Reducer, MAPC probes) are not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use clearly states that the device is for "cutting and coagulation of tissue in open surgery, laparoscopic surgery and endoscopic surgery." This is a therapeutic and surgical application, not a diagnostic one performed on samples outside the body.
- Device Description: The description details a device that generates electrical current for surgical procedures and delivers argon gas for coagulation. This aligns with surgical equipment, not devices used to examine specimens.
- Lack of IVD Characteristics: The description does not mention any components or functions related to analyzing biological samples (blood, urine, tissue samples, etc.) or providing diagnostic information based on such analysis.
In Vitro Diagnostic devices are specifically designed to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. The ESG-300 and its accessories are used directly on the patient's tissue during surgery.

2.7 Substantial Equivalence
Substantial equivalence is demonstrated by acknowledged verification/validation methodologies. The subject devices have equivalent technology, performance, dimensions and materials. The differences to the primary predicate device ESG-400 are:
- only one monopolar socket, no universal socket, vertical alignment of the ● output sockets
- to be used only in conjunction with a double pedal footswitch
- . no PK instruments incorporation
- Monopolar argon plasma coagulation in conjunction with dedicated Olympus accessories
- does not enable the user to select the effect of the output modes
- . GUI modifications (additional strings, languages, sounds, screens, windows)
Regarding the additionally implemented monopolar argon plasma coagulation modes, a secondary predicate device and its required accessories have been chosen, because of their specific output modes. For both the substantial equivalence is demonstrated by acknowledged verification/validation methodologies. The subject device has equivalent technology and performance in respect to the compared modes.
2.8 Performance Data
The following performance data were provided in support of the substantial equivalence determination. All standards applied are FDA recognized international standards.
The data was prepared in accordance with the FDA guidance, Premarket Notification (510(k)) Submissions for Electrosurgical Devices for General Surgery Guidance for Industry and Food and Drug Administration Staff, issued on August 15, 2016. The guidance was followed for all relevant sections.
Biocompatibility testing 2.8.1

2.8.4 Animal Studies
Not applicable.
Clinical Studies 2.8.5
Clinical studies were not conducted for this submission.
Software 2.8.6
The software validation activities were performed in accordance with the FDA Guidance, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices" (May 11, 2005). The device software is considered a "Major Level of Concern".
Performance Testing Bench 2.8.7
To demonstrate substantial equivalence Olympus considered the following subject device aspects in regards to the predicate devices within the design validation:
-
- Performance and validation tests incorporated the same range of waveform outputs and power levels.
- During the validation testing the waveforms and tissue effects were 2. compared directly between the subject and predicate device.
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, biocompatibility, stability) 2) 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.
Stability: Sterile samples were subjected to accelerated aging to confirm that the disposable devices maintain functionality and continue to meet specifications over time. The results of the accelerated age testing demonstrate that the device will be
9
stable for the stated shelf-life. In addition, real time age testing will confirm the results of the accelerated age testing. Samples were also subjected to environmental conditioning and ship testing.
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: porcine muscle for endoscopic procedures, porcine liver for open procedures and porcine kidney for laparoscopic procedures. In accordance with FDA Guidance, Premarket Notification (510(k)) Submissions for Electrosurgical Devices for General Surgery, the thermal damage of the tissue due to the HF current was measured in terms of size (length, width and depth) of the thermal coagulation zone. The tissue effects testing included quantitative and qualitative assessment. Furthermore, each test included the minimum, default and maximum intensity settings. All modes were compared to the predicate. Where the minimum or maximum intensity settings of the test and predicate device differed in terms of output wattage by specification the closest applicable settings were chosen.
In order to exclude variations due to the instrument, the tissue effect was probed with the subject and predicate generators and the same instruments. A representative selection of HF instruments was made that cover the broad spectrum of applications.
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 the three tissue types. Therefore, comparison testing does support that the subject device is substantially equivalent to and is as safe and effective as the legally marketed predicate device.
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.
2.9 Reprocessing, Sterilization and Shelf Life
Required cleaning, disinfecting and drying procedures are described in the instructions for use. Reprocessing of the single use MAPC probes is not applicable. Sterilization of the MAPC probes is performed according to ISO 11135 and packaging conforms to ISO 11607-1. The EtO sterilization cycle has been validated.
A sterility assurance level (SAL) of 10-6 was reached during validation and will be used for routine sterilization in compliance with regulations in force for sterile medical devices.
10
The EtO residuals are within the limits after tunnel degassing time. Shelf Life testing was conducted, including performance testing and package integrity testing, to support a shelf life of 1 year for the MAPC probes.
