The da Vinci E-200 Electrosurgical Generator is intended to deliver high-frequency energy for cutting, coagulation and vessel sealing of tissues in da Vinci robotic procedures, and non-robotic open and laparoscopic procedures.
The da Vinci E-200 is an electrosurgical unit (ESU) designed to provide high-frequency (HF) traditional monopolar, bipolar, and advanced bipolar outputs intended for cutting, coagulation and/or vessel sealing of tissues. The da Vinci E-200 is intended to be used with the IS4000/IS4200 da Vinci surgical systems and also operate as a standalone electrosurgical generator. When connected to the da Vinci surgical system, the E-200 provides HF output to da Vinci instruments. Control and status messages are passed between the E-200 and the da Vinci system through an Ethernet communication cable. The E-200 is also compatible with open and laparoscopic third-party handheld monopolar and bipolar instruments, fingerswitch equipped instruments (where applicable) and Intuitive provided auxiliary footswitches. The primary function of the E-200 Electrosurgical Generator is to allow a surgeon to deliver HF output to cut, seal, or coagulate human tissue during surgery. The user interface includes audible indicator tones, LED indicators on the front of the generator, and status messages provided on its LCD display.
This document is a 510(k) premarket notification for the da Vinci E-200 Electrosurgical Generator, indicating that it is a medical device approval document and not a study on AI-assisted human reading, or a diagnostic AI device. Therefore, many of the requested criteria related to AI studies (e.g., sample size for test/training sets, ground truth establishment, expert adjudication, MRMC studies, standalone performance) are not applicable to this submission.
The document primarily focuses on demonstrating the substantial equivalence of the da Vinci E-200 Electrosurgical Generator to existing predicate devices through bench testing, in-vivo/ex-vivo models, and human factors evaluation, rather than evaluating an AI algorithm's performance in a diagnostic context.
However, I can extract and present the available information regarding the device's performance and acceptance criteria based on the provided text.
1. Table of Acceptance Criteria and Reported Device Performance
Since this is an electrosurgical generator rather than a diagnostic AI device, the "acceptance criteria" are related to its functional performance, safety, and equivalence to predicate devices, rather than typical diagnostic performance metrics (e.g., sensitivity, specificity, AUC). The document outlines various tests conducted to demonstrate the device meets its design requirements and is safe and effective.
| Category of Testing | Acceptance Criteria (Implied by Test Name) | Reported Device Performance (Summary from Document) |
|---|---|---|
| Design Verification | Device meets hardware, EMC, electrical safety, software (including cybersecurity), system interface, instrument compatibility, packaging, and labeling requirements. | "The subject device, E-200 Electrosurgical Generator, was subjected to series of tests to evaluate performance and to demonstrate that the design outputs meet the design input requirements." |
| Design Validation (In-vivo porcine model) | Safety and efficacy of the E-200 generator, its accessories, and its interaction with intended robotic and third-party instruments/accessories in a simulated surgical setting. Device fulfills user needs and intended use is met. | "Design validation demonstrated that the design outputs fulfill the user needs and that the intended use have been met." |
| Thermal Effects Testing | Comparable thermal effects on tissue to the predicate ForceTRIAD generator (K110268). | "The E-200 generator was found to have acceptable thermal effects when compared to the ForceTRIAD generator." |
| Neutral Electrode Contact Quality Monitor (CQM) Study | Conformance to IEC standards for the CQM system. Validation of the use of Covidien E7507 neutral electrode. | "The study validated the use of the Covidien E7507 neutral electrode (commercially available product) with the E-200 generator for CQM functionality." |
| Vessel Sealing Bench Testing (E-200 vs. E-100) | HF output characteristics are substantially equivalent to the predicate E-100 device (K191280) with no differences expected to change vessel sealing performance. | "The test demonstrated that the HF output characteristics of the two generators are substantially equivalent and that there are no differences which would be expected to result in a change in the vessel sealing performance." |
| Capacitive Coupling Evaluation | No significant increase in unintended capacitively coupled energy delivery compared to the predicate Covidien ForceTriad generator. | "This validation demonstrated that the E-200 generator had no significant increase in unintended capacitively coupled energy delivery when compared to the predicate Covidien ForceTriad generator." |
| Human Factors Evaluation (Usability Validation Study) | Safe and effective use of the E-200 generator and associated accessories by intended users in the intended use environment. | "The usability validation study demonstrated that the E-200 electrosurgical generator could be used safely and effectively by the intended users in the intended use environment." |
2. Sample Size Used for the Test Set and Data Provenance
- Test Set Sample Size: The document does not specify a numerical sample size for individual tests like "Design Verification" (bench testing), "Thermal Effects Testing," or "CQM Study." For the in-vivo validation, it mentions a "porcine model," but no specific number of animals or cases. Similarly, "vessel sealing bench testing" and "capacitive coupling evaluation" do not specify sample sizes.
- Data Provenance: The studies appear to be prospective bench tests and animal model studies conducted by the manufacturer, Intuitive Surgical, Inc. The document does not mention the country of origin for the data beyond implying it was conducted as part of the FDA submission process.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of those Experts
This concept is not applicable to this type of device submission. Ground truth in this context refers to the physical and electrical performance of an electrosurgical unit, verified through established engineering and medical device testing standards, rather than expert interpretation of medical images or data. Performance is measured against physical specifications and validated against in-vivo/ex-vivo results.
4. Adjudication Method for the Test Set
This concept is not applicable. Adjudication typically refers to resolving disagreements among human readers or labelers in diagnostic AI studies. The performance validation of an electrosurgical generator involves objective measurements and functional tests, not human interpretation that requires adjudication.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done
No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. This type of study is relevant for evaluating the impact of AI assistance on human reader performance in diagnostic tasks, which is not the purpose of this submission for an electrosurgical generator.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done
Not applicable in the context of AI algorithm performance. The "standalone" operation mentioned in the document refers to the E-200 Electrosurgical Generator operating independently of the da Vinci robotic system, as a traditional ESU. It's a device operating standalone, not an AI algorithm.
7. The Type of Ground Truth Used
The "ground truth" for this device's performance is established by:
- Design Input Requirements/Specifications: The device's performance is validated against its pre-defined engineering and functional requirements.
- Industry and IEC Standards: Conformance to relevant electrical safety and performance standards.
- Predicate Device Performance: Demonstrating comparable performance to legally marketed predicate devices (Covidien ForceTRIAD and Intuitive E-100) through direct comparative testing (e.g., thermal effects, HF output characteristics, capacitive coupling).
- In-vivo/Ex-vivo Models: Actual physiological effects in tissue (e.g., cutting, coagulation, vessel sealing effectiveness) observed in animal (porcine) models and ex-vivo settings.
- User Needs/Safe and Effective Use: Confirmed through human factors evaluation with intended users.
8. The Sample Size for the Training Set
Not applicable. This submission is for an electrosurgical generator, not an AI model, so there is no "training set."
9. How the Ground Truth for the Training Set was Established
Not applicable. As there is no AI model or training set, the concept of establishing ground truth for it does not apply.

Device Description:
The da Vinci E-200 is an electrosurgical unit (ESU) designed to provide high-frequency (HF) traditional monopolar, bipolar, and advanced bipolar outputs intended for cutting, coagulation and/or vessel sealing of tissues. The da Vinci E-200 is intended to be used with the IS4000/IS4200 da Vinci surgical systems and also operate as a standalone electrosurgical generator. When connected to the da Vinci surgical system, the E-200 provides HF output to da Vinci instruments. Control and status messages are passed between the E-200 and the da Vinci system through an Ethernet communication cable. The E-200 is also compatible with open and laparoscopic third-party handheld monopolar and bipolar instruments, fingerswitch equipped instruments (where applicable) and Intuitive provided auxiliary footswitches. The primary
{4}------------------------------------------------
function of the E-200 Electrosurgical Generator is to allow a surgeon to deliver HF output to cut, seal, or coagulate human tissue during surgery. The user interface includes audible indicator tones, LED indicators on the front of the generator, and status messages provided on its LCD display.
Intended Use/Indications for Use:
The da Vinci E-200 Electrosurgical Generator is intended to deliver high-frequency energy for cutting, coagulation and vessel sealing of tissues in da Vinci robotic procedures, and non-robotic open and laparoscopic procedures.
Technological Characteristics:
The Energy modes supported by E-200 include traditional monopolar and bipolar as well as advanced bipolar energy modes as described below.
Monopolar Energy Modes
The generator provides five monopolar modes to support a range of tissue effects, which can be used with compatible monopolar da Vinci instruments or compatible third-party instruments. Descriptions of the generator monopolar energy modes are listed below. The power settings for all monopolar modes can be adjusted from 0-120 watts.
Monopolar Cut Modes ●
Pure: provides clean, precise tissue division with little or no hemostasis. Blend: is a blended waveform that provides tissue division properties with some hemostasis.
Monopolar Coagulation Modes ●
Precise: provides a balance of hemostasis and division capability for precise coagulation energy applications. The width of the tissue effect can be narrower than Fulgurate mode.
Fulgurate: provides coagulation with some tissue division.
Spray: provides coagulation with limited tissue division properties. The width of the tissue effect can be wider compared to Fulgurate mode.
Bipolar Energy Modes
The generator produces four traditional bipolar modes to support a range of tissue effects, which can be used with compatible bipolar da Vinci instruments or compatible third-party instruments. Descriptions of the bipolar energy modes are listed below. The power settings for bipolar energy can be adjusted from 0-95 watts.
{5}------------------------------------------------
● Bipolar modes
Macro: provides high intensity output for tissue division or rapid hemostasis. Standard: provides moderate intensity output for traditional bipolar application. Low: provides low intensity output for precise control over tissue desiccation.
- Low with Auto Stop: provides the same bipolar output as Low and automatically stops delivering bipolar radio frequency (RF) energy based on a pre-determined threshold. Low with Auto Stop is designed to reduce the potential for excessive thermal effect.
Advanced Bipolar Energy Modes
Advanced bipolar energy modes are designed for specific advanced energy instruments, and the algorithms used on the E-200 were developed to functionally replicate those used on the predicate device, the E-100 generator. Like the predicate device, the E-200 generator delivers two bipolar advanced energy modes for sealing and transection of vessels and tissue bundles, and also provides a traditional bipolar coagulation mode that can be used for general hemostasis without vessel sealing. Advanced energy modes are compatible only with da Vinci advanced energy instruments; SynchroSeal (K191280) and Vessel Sealer Extend (K183107).
Advanced Bipolar Modes ●
Coagulation Mode: It is a traditional bipolar mode used for general tissue coagulation and has a fixed target output power of 50 W.
- Sealing Mode: It is designed to seal vessels and tissue bundles when used with the da Vinci Vessel Sealer Extend and SynchroSeal. The generator determines when the seal cvcle is complete thereby delivering the required amount of energy necessary to successfully seal vessels.
- Sync Mode: It is specifically designed for use with SynchroSeal for single-step sealing and transection of vessels and tissue bundles. The Sync mode uses a unique algorithm to control the energy output delivery to the seal and cut electrodes on the instrument. The generator automatically determines when the Sync mode cycle is complete, resulting in a single-step hemostatic transection of vessels and soft tissue.
Performance Data:
The E-200 Electrosurgical Generator was evaluated using design verification (bench testing), human factors testing, packaging(includes transit testing), and validated using in-vivo and exvivo models to demonstrate that the design output meets both the design input requirements and the user needs, and the generator performs as intended.
Design Verification (bench testing):
The subject device, E-200 Electrosurgical Generator, was subjected to series of tests to evaluate performance and to demonstrate that the design outputs meet the design input requirements. The
{6}------------------------------------------------
design verification testing provided confirmation that the device meets the requirements for the following:
- Hardware requirements o
- EMC and Electrical Safety requirements ●
- Software requirements including Cybersecurity ●
- System interface requirements .
- Instrument compatibility requirements ●
- Packaging and Labeling 0
Design Validation; in-vivo testing with a porcine model was used to evaluate the safety and efficacy of the E-200 generator, its accessories and its interaction with intended robotic systems, da Vinci and third-party instruments and accessories in a representative simulated surgical setting. Design validation demonstrated that the design outputs fulfill the user needs and that the intended use have been met.
Thermal effects testing was conducted to demonstrate the ability of the subject E-200 generator to create comparable thermal effects on tissue to the predicate ForceTRIAD generator (K110268), the primary predicate. The E-200 generator was found to have acceptable thermal effects when compared to the ForceTRIAD generator.
Neutral electrode contact quality monitor (CQM) study was conducted to evaluate the performance of the CQM system on the subject E-200 generator for conformance to the IEC standards. The study validated the use of the Covidien E7507 neutral electrode (commercially available product) with the E-200 generator for CQM functionality.
The E-200/E-100 vessel sealing bench testing compared the HF output characteristics of the E-200 to the predicate E-100 device (K191280). The test demonstrated that the HF output characteristics of the two generators are substantially equivalent and that there are no differences which would be expected to result in a change in the vessel sealing performance.
An evaluation of the capacitive coupling behavior of the E-200 generator was performed using third party laparoscopic monopolar accessories which included instruments and cannulas. This validation demonstrated that the E-200 generator had no significant increase in unintended capacitively coupled energy delivery when compared to the predicate Covidien ForceTriad generator.
Human Factors Evaluation:
The Usability Validation Study evaluated the use safety and usability of the E-200 generator along with its associated accessories with intended robotic systems in integrated and standalone
{7}------------------------------------------------
configurations. The usability validation study demonstrated that the E-200 electrosurgical generator could be used safely and effectively by the intended users in the intended use environment.
Summary:
The evaluation of the E-200 Electrosurgical Generator raises no new questions of safety or effectiveness and demonstrates that the E-200 design outputs meet the design input requirements and user needs and is substantially equivalent to the predicate devices, Covidien ForceTRIAD Electrosurgical Generator (K110268) and Intuitive E-100 Electrosurgical Generator (K191280).
