Indications for Use - VIO 3
The Erbe electrosurgical unit (ESU/Generator) model VIO 3 with instruments and accessories is intended to deliver high frequency (HF) electrical current for the cutting and/or coagulation of tissue, including ablation.
Indications for use - ERBECRYO 2
The ERBECRYO 2 cryosurgical unit and accessories are intended for cryoadhesion (destruction) of tissue by the application of extreme cold, and cooling of tissue during radiofrequency ablation.
Indications for use - HybridTherm ablation probes
The HybridTherm probes are intended for ablation and coagulation of soft tissue. The following probes can also be used for cutting tissue: HybridTherm monopolar, eTip and HybridTherm bipolar, eTip.
The HybridTherm system consists of the electrosurgical unit (ESU) Model VIO 3, the cryosurgical unit Model ERBECRYO 2, the HybridTherm ablation probes and accessories.
HybridTherm ablation probes
The HybridTherm probes are a product family consisting of 8 probes to offer the user a range of instruments based upon the physician's preference. There are 4 monopolar and 4 bipolar ablation probes, which differ in the function of the distal end: with and without a monopolar cutting tip (eTip), as well as in their shape (i.e. straight or angulated/curved).
The HybridTherm probes combine high-frequency (HF) technology with cryotechnology. The HF technology is used for cutting (only variants with eTip), coagulation, and ablation of tissue. To reduce tissue desiccation and to increase the ablation zone, the probes are cooled. Cooling also minimizes tissue adhesion to the electrode. The primary function of the cooling is to support the ablation process.
VIO 3
The ESU Model VIO 3 delivers high frequency (HF) electrical current for cutting, coagulation and ablation of tissue. The unit can be mounted/secured to a cart/system carrier or on a ceiling mount. Different Footswitches are available for activating the ESU and as applicable to change modes of the ESU (Remode feature). The ESU Model VIO 3 has several clearly defined cutting, coagulation and ablation modes with different electrical waveforms and electrical parameters that are programmed with defined effect levels. Each effect level corresponds to a defined maximum power output and a voltage limitation. The ESU has a touchscreen monitor that provides the user with an onscreen tutorial as well as settings and operational information. It also provides a small number of physical controls, such as the power switch, instrument sockets and a neutral electrode receptacle.
ERBECRYO 2
The cryosurgical unit Model ERBECRYO 2 is connected to an electrical power source and a carbon dioxide (CO2) source. Upon activation, the Unit delivers a regulated CO2flow to the end of the connected instrument for cooling. The CO2 returning from the probe to the ERBECRYO 2 exists via the exhaust gas hose. Appropriate gas cylinder adapters are available for the various international gas cylinder connections.
HybridTherm System
The HybridTherm probes are connected to the units (VIO 3 and ERBECRYO 2) via respective plugs. The units are connected to each other via an Erbe Communication Bus (ECB) cable, whereby the user only interacts with the ESU Model VIO 3 (master-slave technology: the cryosurgical unit is controlled via the VIO 3). The ERBECRYO 2 additionally requires a CO2 gas cylinder. A footswitch is connected to the ESU, with which the activation of the available modes is started. The ESU supplies the HF current which is needed for cutting (only HybridTherm probe variants with eTip), coagulation and ablation of tissue. The ERBECRYO 2 supplies CO2 gas which is needed for cooling via the Joule-Thomson-effect to support the ablation.
The provided text is a 510(k) summary for the HybridTherm System. It focuses on demonstrating substantial equivalence to predicate devices, primarily through comparison of technical characteristics and non-clinical performance testing. It does not include information about AI/ML models, human reader studies, or the establishment of ground truth for such studies.
Therefore, many of the requested details about acceptance criteria, human performance, and ground truth are not present in this document. The information provided heavily emphasizes hardware and traditional medical device testing rather than algorithmic performance.
Here's what can be extracted and what cannot:
1. A table of acceptance criteria and the reported device performance
The document mentions "Side-by-side tissue testing against the respective predicate device(s) shows that the performance (i.e. cutting, coagulation and ablation) is as good as the performance of the predicate device(s)." This indicates a comparative performance acceptance criterion, but specific numerical thresholds or a formal table are not provided in this summary. The acceptance criterion is qualitative: performance is "as good as" the predicate.
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
Not applicable. This was "side-by-side tissue testing," likely in a lab setting, not a clinical study with patients or image-based data. No information on sample size (e.g., number of tissue samples), country of origin, or retrospective/prospective nature is given.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
Not applicable. Ground truth for the "tissue testing" was likely established through objective measurements of ablation zone size or tissue characteristics, not expert consensus (as there are no images or clinical interpretations involved).
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable. There's no indication of adjudication for "tissue testing."
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
No. The document explicitly states "Side-by-side tissue testing" and discusses engineering safety and performance standards (e.g., electrical safety, EMC, biocompatibility, sterilization). There is no mention of a human reader study or AI assistance.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
No. This device is a physical electrosurgical system, not an AI algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
For the "side-by-side tissue testing," the ground truth would be physical measurements of the effect on tissue (e.g., ablation zone size, tissue integrity) rather than expert consensus or pathology from human subjects. The document does not specify the exact methods but implies objective performance metrics.
8. The sample size for the training set
Not applicable. There is no AI/ML model for which a training set would be defined.
9. How the ground truth for the training set was established
Not applicable, as there is no AI/ML model or training set.

Device Description
The HybridTherm system consists of the electrosurgical unit (ESU) Model VIO 3, the cryosurgical unit Model ERBECRYO 2, the HybridTherm ablation probes and accessories.
HybridTherm ablation probes
The HybridTherm probes are a product family consisting of 8 probes to offer the user a range of instruments based upon the physician's preference. There are 4 monopolar and 4 bipolar ablation probes, which differ in the function of the distal end: with and without a monopolar cutting tip (eTip), as well as in their shape (i.e. straight or angulated/curved).
The HybridTherm probes combine high-frequency (HF) technology with cryotechnology. The HF technology is used for cutting (only variants with eTip), coagulation, and ablation of tissue. To reduce tissue desiccation and to increase the ablation zone, the probes are cooled. Cooling also minimizes tissue adhesion to the electrode. The primary function of the cooling is to support the ablation process.
VIO 3
The ESU Model VIO 3 delivers high frequency (HF) electrical current for cutting, coagulation and ablation of tissue. The unit can be mounted/secured to a cart/system carrier or on a ceiling mount. Different Footswitches are available for activating the ESU and as applicable to change modes of the ESU (Remode feature). The ESU Model VIO 3 has several clearly defined cutting, coagulation and ablation modes with different electrical waveforms and electrical parameters that are programmed with defined effect levels. Each effect level corresponds to a defined maximum power output and a voltage limitation. The ESU has a touchscreen monitor that provides the user with an onscreen tutorial as well as settings and operational information. It also provides a small number of physical controls, such as the power switch, instrument sockets and a neutral electrode receptacle.
ERBECRYO 2
The cryosurgical unit Model ERBECRYO 2 is connected to an electrical power source and a carbon dioxide (CO2) source. Upon activation, the Unit delivers a regulated CO2flow to the end of the connected instrument for cooling. The CO2 returning from the probe to the ERBECRYO 2 exists via the exhaust gas hose. Appropriate gas cylinder adapters are available for the various international gas cylinder connections.
HybridTherm System
The HybridTherm probes are connected to the units (VIO 3 and ERBECRYO 2) via respective plugs. The units are connected to each other via an Erbe Communication Bus (ECB) cable, whereby the user only interacts with the ESU Model VIO 3 (master-slave technology: the cryosurgical unit is controlled via the VIO 3). The ERBECRYO 2 additionally requires a CO2 gas cylinder. A footswitch is connected to the ESU, with which the activation of the available modes is started. The ESU supplies the HF current which is needed for cutting (only HybridTherm probe variants with eTip), coagulation and ablation of tissue. The ERBECRYO 2 supplies CO2 gas which is needed for cooling via the Joule-Thomson-effect to support the ablation.
{6}------------------------------------------------
Indications for Use
HybridTherm probes
The HybridTherm probes are intended for ablation and coagulation of soft tissue. The following probes can also be used for cutting tissue: HybridTherm monopolar, eTip and HybridTherm bipolar, eTip.
VIO 3
The Erbe electrosurgical unit (ESU/Generator) Model VIO 3 with instruments and accessories is intended to deliver high frequency (HF) electrical current for the cutting and/or coagulation of tissue, including ablation.
ERBECRYO 2
The ERBECRYO 2 cryosurgical unit and accessories are intended for cryoadhesion, devitalization (destruction) of tissue by the application of extreme cold, and cooling of tissue during radiofrequency ablation.
Compared to the predicate device(s), the VIO 3 and the HybridTherm probes have the same intended use. All devices are intended for the application of high frequency (HF) electrical energy in interventional/surgical procedures to thermally effect or destroy tissue.
Compared to the previously cleared cryosurgical unit (ERBECRYO 2), the ERBECRYO 2 that is part of the HybridTherm System has an extended Indications for Use statement (i.e. cooling of tissue during radiofrequency ablation). However, the intended use of both devices is the supply of CO2 to a connected instrument for cooling via the Joule-Thomson effect. This function is the same for the predicate system. The VIVA Combo RF Generator in combination with the EUSRA RF Electrode uses a peristaltic pump with chilled water to cool the probe/tissue during the application. Therefore, the intended use is essentially the same.

Comparison of Technological Characteristics
Differences of the ESU Model VIO 3 compared to the previously cleared device is an updated software mainly to introduce new modes for cutting, coagulation and ablation of tissue, remote control of the cryosurgical unit ERBECRYO 2 and operation/control of the HybridTherm probes.
Compared to the primary predicate device EUSRA RF Electrode the HybridTherm probes have an additional bipolar variant, a monopolar cutting tip (only variants with eTip) and a lateral and distal coagulation feature. The HybridTherm probes are cooled via CO2 compared to cooling via chilled water which is employed by the predicate probes. In addition, the HybridTherm probes have different materials and different physical specifications which are, however, within the specifications of the respective predicate devices.
Difference of the ERBECRYO 2 compared to the predicate device is an updated software for remote control via the VIO 3 and operation/control of the HybridTherm probes.
The subject device system and the predicate device(s) use the same enerqy (HF electrical current) and principles of operation. Both the monopolar and bipolar technology are established and routinely adopted in interventional procedures for many years. Compared to the monopolar variant, the bipolar variant does not raise different issues of safety and effectiveness. The cooling technology of the subject device by means of CQ2 is the same compared to the previously cleared ERBECRYO 2. Although the predicate system uses a different cooling technology (chilled water), the purpose of the same and the cooling is only used to support the ablation process.
Side-by-side tissue testing against the respective predicate device(s) shows that the performance (i.e. cutting, coagulation and ablation) is as good as the performance of the predicate device(s). The non-clinical testing described below shows that the different technological characteristics do not negatively affect the safety and effectiveness of the subject device.
