The SYLFIRM X™ is intended for use in dermatologic procedures for electrocoagulation and hemostasis.
The SYLFIRM X™ includes a system main device, a hand-piece equitable with a bi-polar electrode, and a foot switch. The RF signal is generated from the main device which is then delivered to the handpiece and then to bi-polar electrode. The RF signal is delivered to the target tissue using penetrating needle electrodes in the consumable tip. The bi-polar electrode is placed in light contact with the epidermis while the hand-piece is being held at right angles to the target tissue. As the RF signal passes through the skin, it generates an electro thermal reaction which is capable of coagulating the tissue. Using the consumable tip, SYLFIRM X™ creates heat within the target skin tissue via needle electrodes from the bi-polar electrode.
The provided text describes the Sylfirm X, an electrosurgical cutting and coagulation device. The document is a 510(k) summary submitted to the FDA for market clearance. It doesn't contain information about AI or machine learning algorithms, so there are no acceptance criteria, performance metrics, or study details related to such technologies.
The document primarily focuses on demonstrating substantial equivalence to a predicate device (also Sylfirm X, K200185) for its intended use in dermatologic procedures for electrocoagulation and hemostasis.
Therefore, I cannot provide the requested information about acceptance criteria, study details, sample sizes, expert ground truth, or MRMC studies because the provided text is for a medical device that does not involve AI/ML.
However, I can extract information regarding the device's performance testing for general safety and efficacy:
Device Performance Testing (Preclinical):
- Study Design: The study evaluated the safety and effectiveness of SYLFIRM X™ as a radiofrequency (RF) heating device to treat dermal conditions and hemostasis.
- Sample Size: Three (3) Yucatan Mini-pigs were used.
- Observation Periods:
- Animal G1: Euthanized 3 hours after treatment on Day 1.
- Animal G2: Euthanized on Day 5.
- Animal G3: Euthanized on Day 22.
- Findings:
- Gross Observations: No erythema or edema formation observed within 1-hour post-treatment or at any other scheduled time points on any animals.
- Microscopic Findings:
- Animals euthanized on Days 1 and 5: Minimal to moderate, multifocal deep dermal collagen necrosis.
- Animal euthanized on Day 22: Minimal to mild multifocal deep dermal fibrosis.
- Conclusion: Test results, including histology data, demonstrated that the subject device is substantially equivalent to the predicate devices in the market for its intended use.
Additional Tests Conducted to support substantial equivalence (not AI/ML related):
- Sterilization Validation Test: Verified sterility assurance level (10-6) for EO sterilization using the biological indicator (BI) overkill method, in accordance with ISO 11135-1, ISO 10993-1, ISO 10993-7, ISO 11138-1, ISO 11138-2, ISO 11737-1, ISO 11737-2, AAMI TIR 15, and ISO 13485:2016.
- Shelf-life Validation Test: Conducted using the accelerated aging method in accordance with ASTM F1980-07 (2011) and referenced standards ISO 11607-1, ISO 11607-2, ISO 11737-2, ASTM F1929, ASTM F 88, and USPNF.
- Biocompatibility Test: Performed on the patient-contacting component (J25BM) in accordance with ISO 10993-5, ISO 10993-10, ISO 10993-11, and USP 38 <661>.
- Software Validation Test: Performed for the device's firmware, which was determined to have a "moderate" level of concern.
- EMC & Electrical Safety Test: Evaluated according to IEC 60601-1:2005, IEC 60601-1:2012, IEC 60601-1-6:2010, IEC 60601-1-6:2010/AMD1:2013, IEC 60601-2-2:2017, CISPR 11:2009/AMD1:2010, and IEC 60601-1-2:2014.
- Verification (for new accessories): Performance tests were done to confirm the same performance for added bi-polar tips (J25BM, J25BS, J18BS).
Note: The document only lists the types of tests performed and their general conclusions (e.g., "demonstrated that the subject device is substantially equivalent"). It does not provide specific numerical acceptance criteria (e.g., "sensitivity must be >X%") or quantitative results. The standard for a 510(k) clearance is to demonstrate substantial equivalence to a predicate device, not necessarily to meet specific quantitative performance benchmarks as would be expected for a novel AI/ML device.

The SYLFIRM X™ has same intended uses and technical characteristics to the predicate device, SYLFIRM X™(K200185). We performed risk analysis according to the addition of an accessory, and performed necessary verification and validation accordingly. There is no additional consideration for safety and effectiveness, so subject device, SYLFIRM X is substantially equivalent to the predicated device.
8. Performance data
Sterilization validation test
To verify the sterility assurance level (10-6) for EO sterilization and biological indicator (BI) overkill method was used in accordance to ISO 11135-1, ISO 10993-1, ISO 10993-7, ISO 11138-1, ISO 11138-2, ISO 11737-1, ISO 11737-2, AAMI TIR 15, and ISO 13485:2016.
Shelf-life validation test
The tests to validate the shelf life of the device through the proposed shelf life were conducted using the accelerated aging method in accordance to ASTM F1980-07 (2011) Standard Guide for Accelerated Aging of Sterile Barrier Systems for Medical Devices. The referenced standards for the testing are ISO 11607-1, ISO 11607-2, ISO 11737-2, ASTM F1929, ASTM F 88, and USPNF.
Biocompatibility test
The patient contacting component of the subject device is the J25BM and the biocompatibility tests were in accordance with ISO 10993-5, ISO 10993-10, ISO 10993-11, and USP 38 <661>.
Software validation test
The level of concern of the software (firmware) of the SYLFIRM X™ is moderate and the software validation tests were performed.
EMC & Electrical safety test
{7}------------------------------------------------
The subject device has been evaluated for electromagnetic compatibility and electrical safety testing per applicable standards of IEC 60601-1:2005. IEC 60601-1:2012: IEC 60601-1-6:2010. IEC 60601-1-6:2010/AMD1:2013; IEC 60601-2-2:2017, CISPR 11:2009/AMD1:2010, IEC 60601-1-2:2014.
Preclinical test
The study was designed to evaluate the safety and effectiveness of SYFLIRM X™ as a radiofrequency(RF) heating device to treat dermal conditions and hemostasis. Three (3) Yucatan Mini-pigs were used in this study. Animal G1 was euthanized 3 h after treatment on Day 1; Animal G2 was euthanized on Day 5; and Animals G3 was euthanized on Day 22.
Treatment with the SYLFIRM X™ device did not result in erythema or edema formation within 1-hour post treatment, nor at any other scheduled time points on all animals. The treatment-related microscopic findings consisted of minimal to moderate, multifocal deep dermal collagen necrosis in animals euthanized on Days 1 and 5, and minimal to mild multifocal deep dermal fibrosis on animal euthanized on Day 22.
Test results including histology data demonstrated that the subject device is substantially equivalent to the predicate devices in the market for its intended use.
Verification
The bi polar tip (J25BM, J25BS, J18BS) was added without changing the safety or effectiveness of the initially approved equipment, and related performance tests were performed to confirm the same performance. It was confirmed that it has the same performance for additional accessories.
9. Conclusion [21 CFR 807.92(b)(3)]
Based on the test results provided in this submission including Sterilization Validation, Shelf life Validation, Biocompatibility, Software Validation, EMC & Electrical Safety Test, and Animal Test, VIOL Co., Ltd. concludes that the SYLFIRM X™ is substantially equivalent to the predicate device as described herein in.
