The description focuses on the electrothermal mechanism of action and does not mention any AI/ML components or functions.
No
The device is intended for dermatologic procedures for electrocoagulation and hemostasis, which aim to eliminate or control symptoms rather than restore or replace a physiological function.
No
The device is used for electrocoagulation and hemostasis in dermatologic procedures, which are therapeutic actions, not diagnostic ones.
No
The device description explicitly details hardware components including a system main device, handpiece, bipolar electrode, and consumable tips with needle electrodes. It describes the generation and delivery of an RF signal through these physical components to the target tissue.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for "dermatologic procedures for electrocoagulation and hemostasis." This describes a therapeutic or surgical procedure performed directly on the patient's skin.
- Device Description: The device generates an RF signal and delivers it to tissue via needle electrodes to create heat for coagulation. This is a physical intervention on the body.
- Lack of In Vitro Activity: IVD devices are used to examine specimens (like blood, urine, tissue samples) outside of the body to provide information about a person's health. This device does not interact with specimens in this way.
- Performance Studies: The performance studies describe applying the device to animal tissue in vivo (on living animals) to assess tissue response and healing, which is consistent with a therapeutic device.
Therefore, the RM STAR EX with RMS Needle is a therapeutic device used for dermatologic procedures, not an in vitro diagnostic device.

Device Description
The RM STAR EX with RMS Needle includes a system main device and a handpiece equitable with a bipolar electrode. The RF signal is generated from the main device which is then delivered to the handpiece and then to bipolar electrode. The RF signal is delivered to the target tissue using penetrating needle electrodes in the consumable tip. The bipolar electrode is placed in light contact with the epidermis while the handpiece is being held at right angles to the target tissue. As the RF signal passes through the skin, it generates an electrothermal reaction which is capable of coagulating the tissue. Using the consumable tip, RM STAR EX with RMS Needle creates heat within the target skin tissue via needle electrodes from the bipolar electrode.

Summary of Performance Studies
- Biocompatibility Testing: In accordance with ISO 10993-1, the subject device is classified as an externally communicating device in contact with tissue/bone/dentin for limited duration ( Medical Devices -. Bacterial Endotoxin and Pyrogen Tests and USP Bacterial Endotoxins Test. Package integrity testing, after environmental conditioning and simulated transportation using ASTM D4169-22, was conducted on final packaged and sterile devices. Sterile Barrier Packaging Testing was performed on the proposed device: Seal peel test - ASTM F88/F88M-15 and Dye penetration ASTM F1929-15. Shelf life of 3 years is validated using the FDA-recognized standard ASTM F1980-21 Standard Guide for Accelerated Aging of Sterile Barrier System for Medical Devices.
- Electrical Safety and EMC Test: The subject device has been evaluated for electrical safety and electromagnetic compatibility in accordance with the relevant standards, including IEC 60601-1:2005/AMD2:2020, IEC 60601-1-2:2014/A1:2020, IEC 60601-2-2:2017/AMD1:2023, IEC TR 60601-4-2:2016, EN 55011:2016 + A1:2017 (CISPR 11:2015/A1:2016), and IEC 61000-3-2:2018/AMD1:2020.
- Software Validation Test: The level of concern of the software of RM STAR EX with RMS Needle is moderate, and the software validation tests were performed.
- Pre-clinical Test: The RM STAR EX with RMS Needle was evaluated for safety and effectiveness through comprehensive pre-clinical testing using both internal organs and skin models.
- Study Design: Radiofrequency (RF) microneedling was applied to liver, kidney, and muscle as well as the skin of rabbits to assess the localized effects of RF energy. The animals were euthanized at different time points (3 hours, 5 days, and 22 days post-treatment) to observe tissue response and healing.
- Tissue Reactions: In the internal organ models, minimal hemorrhage and fibrosis were observed, with no significant gross lesions at any time point. In the skin model, mild dermal necrosis was observed shortly after treatment, but the tissue exhibited good recovery, with minimal fibrosis noted by Day 22.
- Histological Findings: Histopathological analysis showed that the tissue damage was localized and well-controlled, with signs of tissue healing and regeneration over time. No major adverse reactions were observed in either the skin or internal organs.
- Conclusion: The RM STAR EX with RMS Needle demonstrated controlled tissue interaction with no adverse effects and effective healing in both skin and internal organ models, confirming the safety and effectiveness of the device.

Note 1: Conduction time
The conduction time of the subject device is 100 msec to 200 msec and continuous. The conduction time of the predicate device is 120 msec to 300 msec.
These differences in conduction time do not raise different questions of safety and effectiveness because conduction time of the subject device is shorter than that of the predicate device.
The safety and effectiveness of the subject device was supported by animal test (Doc. No. NT24-00035, NT24-00036).
Note 2: Depth
The depth of the subject device is 0 to 2.0 mm.
The depth of the predicate device is 0.3 to 4.0 mm.
These differences in depth do not raise different questions of safety and effectiveness because depth of the subject device is not greater than that of the predicate device. The safety and effectiveness of the subject device was supported by animal test (Doc. No. NT24-00035, NT24-00036).
Note 3: Number of electrodes
The number of electrodes of the subject device is 13 pins. The number of electrodes of the predicate device is 25 pins.
7
These differences in number of electrodes do not raise different questions of safety and effectiveness because the number of electrodes of the subject device is fewer than that of the predicate device.
The safety and effectiveness of the subject device was supported by animal test (Doc. No. NT24-00035, NT24-00036).
Based on the above comparison as well as the information provided in the SE Comparison Table in Section VI, supported by the appropriate performance data, the proposed device has been shown to be as safe and effective as the legally marketed predicate device for the proposed Indications for Use.
