Intended Use

AGNES RF (DL) handpiece, AGNES RF (F) handpiece and AGNES RF (B) handpiece of AGNES Ultra are intended for use in dermatologic and general surgical procedures for electrocoagulation and hemostasis.

Device Story

AGNES Ultra is a monopolar radiofrequency (RF) electrosurgical device used in dermatology and general surgery for tissue coagulation and hemostasis. The system comprises a main console with an LCD interface, handpieces (DL, F, and B models), disposable micro-needle electrodes, a neutral electrode pad, and a footswitch. The operator selects parameters (output levels 0-20, 2-32W; duration 50-2000ms) via the console. RF energy is delivered through the micro-needle electrode into the patient's tissue. The device includes a negative pressure function (levels 1-3) to assist in tissue contact. The output is an oscillating rectangular wave at 1MHz. The device is operated by healthcare professionals in clinical settings. By delivering controlled RF energy, the device achieves localized coagulation, aiding in hemostasis during surgical procedures.

Clinical Evidence

No clinical data was performed. Evidence consists of bench testing, electrical safety/EMC testing, biocompatibility testing (ISO 10993), and an ex vivo study on liver, skin, and muscle tissue to verify thermal performance in accordance with FDA guidance for electrosurgical devices.

Technological Characteristics

Monopolar RF electrosurgical device; 1MHz output frequency; oscillating rectangular waveform; 0-32W output power; 50-2000ms duration.

Clinical Testing Clinical testing is not a requirement and has not been performed. ## 9. Conclusion The AGNES Ultra and the predicate device have same indication for use, Technology, mechanism of actions, operational principles and performance for the proposed indications for use. The non-clinical data for proposed device, including biocompatibility, bench testing, hardware, and software documentation shows that the device should perform as intended in the specified use. In addition, the Electromagnetic Compatibility and Electrical Safety testing shows that the device is safe. The comparison between the subject devices and the predicate devices shows that the indication for use and technological characteristic is substantially equivalent although there are some differences, the performance test reports are supported to the substantial equivalence of the subject device, the performance test reports are provided to demonstrate substantial equivalence of the subject devices. Therefore, we conclude that the different characteristics do not raise different questions of safety and effectiveness, and thus the subject devices are substantially equivalent to the predicate devices. 510(k) Summary. 8 / 8 page
