No
The description focuses on the mechanical and electrical components of an RF tissue coagulation device. There is no mention of AI or ML in the intended use, device description, or the specific sections for AI/ML information.
Yes
The device is described as a "Tissue Coagulating Electrode" intended for "coagulation and reduction of enlarged tonsils," which are direct therapeutic actions.
No
The device is described as a tissue coagulating electrode intended for the coagulation and reduction of enlarged tonsils, which is a therapeutic rather than a diagnostic function.
No
The device description clearly details a physical electrode with needles, a guide sleeve, a handle, and temperature sensors, indicating it is a hardware device used to deliver RF energy.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices intended for use in the examination of specimens derived from the human body in order to provide information for diagnostic, monitoring, or compatibility purposes. This typically involves tests performed on samples like blood, urine, or tissue outside of the body.
- Device Function: The Gyrus ENT Somnoplasty® Model 2420 Tissue Coagulating Electrode is a surgical device used to directly treat tissue within the body (coagulation of enlarged tonsils). It delivers RF energy for therapeutic purposes, not for analyzing a specimen to diagnose or monitor a condition.
- Intended Use: The intended use clearly states "coagulation of tissues in the head and neck" and "coagulation and reduction of enlarged tonsils." This is a therapeutic intervention, not a diagnostic test.
The device description and intended use clearly indicate it's a surgical tool for tissue modification, not a device for analyzing biological samples.

Device Description
The Somnoplasty® System is comprised of three principal elements: (1) the Model 2420 Disposable Tissue Coagulating Electrode; (2) the Model RC-20 Reusable Cable*; and (3) the Modified Model S2 Electrosurgical Generator*, or another two-channel Gyrus electrosurgical generator. Previous versions of the Somnoplasty® System have been cleared for use in soft tissue coagulation in the uvula/soft palate (K971450), treatment of nasal obstruction due to chronic turbinate hypertrophy (K973618), and reduction of the incidence of airway obstructions in patients suffering from UARS or OSAS (K982717). *In addition, the current Model S2 Generator was cleared for use in conjunction with disposable soft tissue coagulation electrodes in K001438, and the RC-20 Cable was cleared in K000720.
The Model 2420 Tissue Coagulating Electrode also is substantially the same as the Model 1420 Electrode that was cleared in K000720. Thus, there are no significant differences in design or technological features between the current Somnoplasty® System and the company's previously cleared products. A brief description of each of the components of the current System is provided below.
The Model 2420 Tissue Coagulating Electrode is used to deliver RF energy for selective thermal coagulation of tissue. The electrode is provided as a dual needle that is deployed from a guide sleeve. The angle of deployment is fixed at approximately 45°. The needle is covered proximally by insulation to protect the mucosa during coagulation. A beveled penetrator plate is located at the tip of the guide sleeve and serves to penetrate the tonsil mucosal surface prior to electrode deployment. Temperature sensors located at the tip of the needle and the tip of the insulation monitor lesion temperature.
Like the previously cleared Model 1420 electrode, the Model 2420 provides a slide actuator on the handle used to extend or retract the needle electrodes through attached dual guide lumens. The proximal end of the handle accepts the detachable and reusable power cable. The distal end of the handle is attached to the guide lumens containing the needle electrodes. The entire device is disposable.
