The description focuses on the hardware (generator, applicators) and the energy delivery mechanism (microwave, radiofrequency) for thermoablation. There is no mention of AI or ML in the device description, intended use, or performance studies. The device is described as an evolution of a previously cleared device, focusing on smaller applicator size and different energy delivery options, not on intelligent processing or decision-making.
Yes
The device is described as an "integrated system for thermoablation of tissues" intended for "coagulation (thermoablation) of soft tissue," which directly implies its use in treating a medical condition or altering the structure/function of the body.
No
Explanation: The device is described as a system for "thermoablation of tissues" and "coagulation (thermoablation) of soft tissue," which are therapeutic procedures, not diagnostic ones.
No
The device description explicitly lists hardware components: programmable generators and disposable applicators (probes). The submission also includes validation testing for electrical safety and electromagnetic compatibility, which are hardware-related tests.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "Coagulation (thermoablation) of soft tissue." This describes a therapeutic procedure performed directly on the patient's body, not a test performed on a sample taken from the body.
- Device Description: The device is described as a system for "thermoablation of tissues through controlled emission of nonionizing electromagnetic radiations." This is a description of a medical device used for treatment, not for diagnosing conditions based on in vitro analysis.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.) or providing diagnostic information based on such analysis.
IVD devices are specifically designed to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device's function is to directly treat tissue.

Device Description
The devices subject of this submission, generator AGN-H-1.3, generator AGN-3.3 and AMICA-PROBE 17G & 18G applicators, belong to the HS AMICA devices family and they represent an evolution and implementation of previous models, already authorized by FDA under K182605. The working configuration of the HS AMICA commercial system consists of:
- . A programmable generator for the generation and control of the energy required for the thermoablative treatment;
- . Disposable applied parts (or applicators) for the direct release of energy into the patients or for temperature measurements inside the patient's body.
The result is an integrated system for thermoablation of tissues through controlled emission of nonionizing electromagnetic radiations in the microwave and radiofrequency ranges. The generators and its accessories are able to emit only microwaves (MW, 2450 MHz), or only radiofrequency waves (RF, 450 kHz) or either microwaves or radiofrequency waves (not simultaneously). The new electrosurgical devices introduced by H.S. Hospital Service S.p.A. are the AMICA-GEN models named AGN-H-1.3 and AGN-3.3, along with 17G and 18G AMICA-PROBE disposable applicators.
AGN-H-1.3 and AGN-3.3, are identical to the approved AMICA-GEN models named AGN-H-1.2 and AGN-3.2, respectively, as for principles of operation, design, architecture, and critical components; however, the new models feature a higher MW rated power, increased from 190W to 250W. This power increase solely affects the PULSED energy delivery mode and does not alter the total amount of microwave energy that the HS AMICA system may administer to a patient in a single treatment session. To support the increased MW power rating, new generator models use AC-DC power supply units with 600W DC output, whereas previously approved models used 500W AC-DC power supply units.
Both new AMICA-GEN models and previously approved models feature a monochromatic touchscreen LCD display (serving as human-machine interface), a rotary knob for parameters selection, a set of connection ports, buttons and indicators, and a built-in peristaltic pump for inner convective cooling of the applied parts used in conjunction with the generator: none of these features is changed in new models with respect to previously approved models.
The new variants of AMICA-PROBE disposable applicators are characterized by a smaller diameter of the needle and shaft length options limited to 70mm, 100mm or 150mm; these applicators better serve the purpose of further minimizing treatment invasiveness and further enhancing safety in clinical applications that prioritize the tailoring of the treatment area to the target tissues geometry rather than the absolute maximization volume. The new models of AMICA-PROBE share the same performance specifications and the same manufacturing materials with already approved applicators (K182605). The difference with previous models resides in the probe gauge (i.e., the outer diameter of the introducing cannula), which is 17G and 18G in the new models vs 11G, 14G or 16G in the previously approved devices.

4. Device Description
The devices subject of this submission, generator AGN-H-1.3, generator AGN-3.3 and AMICA-PROBE 17G & 18G applicators, belong to the HS AMICA devices family and they represent an evolution and implementation of previous models, already authorized by FDA under K182605.

- . A programmable generator for the generation and control of the energy required for the thermoablative treatment;
- . Disposable applied parts (or applicators) for the direct release of energy into the patients or for temperature measurements inside the patient's body.

The result is an integrated system for thermoablation of tissues through controlled emission of nonionizing electromagnetic radiations in the microwave and radiofrequency ranges. The generators and its accessories are able to emit only microwaves (MW, 2450 MHz), or only radiofrequency waves (RF, 450 kHz) or either microwaves or radiofrequency waves (not simultaneously). The new electrosurgical devices introduced by H.S. Hospital Service S.p.A. are the AMICA-GEN models named AGN-H-1.3 and AGN-3.3, along with 17G and 18G AMICA-PROBE disposable applicators.
AGN-H-1.3 and AGN-3.3, are identical to the approved AMICA-GEN models named AGN-H-1.2 and AGN-3.2, respectively, as for principles of operation, design, architecture, and critical components; however, the new models feature a higher MW rated power, increased from 190W to 250W. This power increase solely affects the PULSED energy delivery mode and does not alter the total amount of microwave energy that the HS AMICA system may administer to a patient in a single treatment session. To support the increased MW power rating, new generator models use AC-DC power supply units with 600W DC output, whereas previously approved models used 500W AC-DC power supply units.
Both new AMICA-GEN models and previously approved models feature a monochromatic touchscreen LCD display (serving as human-machine interface), a rotary knob for parameters selection, a set of connection ports, buttons and indicators, and a built-in peristaltic pump for inner convective cooling of the applied parts used in conjunction with the generator: none of these features is changed in new models with respect to previously approved models.
The new variants of AMICA-PROBE disposable applicators are characterized by a smaller diameter of the needle and shaft length options limited to 70mm, 100mm or 150mm; these applicators better serve the purpose of further minimizing treatment invasiveness and further enhancing safety in clinical applications that prioritize the tailoring of the treatment area to the target tissues geometry rather than the absolute maximization volume.

The difference with previous models resides in the probe gauge (i.e., the outer diameter of the introducing cannula), which is 17G and 18G in the new models vs 11G, 14G or 16G in the previously approved devices.
As predicate devices, the new applicators are supplied in sterile conditions and cannot be resterilized; the sterile kits composed by the microwave applicators and their disposable accessories (a scalpel for skin pre-incision, and a self-adhesive drape for better delimitation of the operating area) are the same as for predicate devices. The sterilization method used for the sterile kits is Ethylene Oxide (unchanged with respect to what was described and validated in K182605).

None of the performance or technological differences between the new HS AMICA family devices and the identified predicate devices raises new questions of safety and effectiveness.
7. Performance Data
Subject devices have been subjected to validation testing for electrical safety, electromagnetic compatibility and software verification and validation. These tests verified and validated the proper operation and the performance of the system. The new applied parts of the system are represented by new AMICA PROBE applicators characterized by a smaller diameter compared to already authorized probes. The materials used to manufacture them are the same of the already authorized devices (K182605). These applied parts are provided in sterile condition, which was revalidated. This present in 8. Conclusion.
Biocompatibility
Biocompatibility testing was not necessary, as the proposed devices are manufactured using the same materials of predicate devices.
Electrical safety and Electromagnetic compatibility
The HS AMICA family generators, AMICA-GEN AGN-3.3 and AGN-H-1.3, have been tested for electrical safety according to IEC 60601-2-6 and IEC 60601-2-2 and for electromagnetic compatibility (EMC) according to IEC 60601-1-2. They comply with all of the medical electrical safety and electromagnetic compatibility requirements.
Software verification and validation
The software of the HS AMICA devices family has been validated according to Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices requirements FDA— May 2005 and IEC 62304, and it demonstrated to be safe and effective for its intended use. The software is a Moderate Level of Concern as per FDA guidance. All required items related to software by FDA guidance and modified with respect to the original Submission have been included in this submission.
The changes introduced to adapt the functioning of the new applicators can be considered marginal and therefore only a few validation tests have been performed and only the
9
documents involved in the changes have been updated with respect to those of the previous Submission (K182605).
It is believed that the documentation developed in recent years up to now can be considered consistent also in the light of the new Guideline "Content of Premarket Submission for Device Software Function" issued on June 14, 2023.
Performance bench testing
Hs Hospital Service Spa conducted an ex-vivo test in order to validate the functional ablation performances of the new 18G-gauge AMICA-PROBE applied part. This new probe represents the thinnest of the applicators present in this family. The measurements performed support the use of the "moving shot" technique, which best suits the thin probes operation.
8. Conclusions
