This device is intended for use by qualified medical personnel trained in the use of electrosurgery. The Bipolar Generator section of the G3 RF Workstation is indicated for ablation, resection and coagulation of soft tissue and hemostasis of blood vessels in otorhinolaryngology (Head and Neck) surgery including: - Adenoidectomy . - Cysts . - Head, Neck, Oral, and Sinus Surgery - Mastoidectomy - Myringotomy with effective Hemorrhage Control - Nasal Airway Obstruction by Reduction of Hypertrophic Nasal Turbinates - Nasopharyngeal / Laryngeal indications including Tracheal Procedures, Laryngeal - Polypectomy, and Laryngeal Lesion Debulking - Neck Mass - Papilloma Keloids - Submucosal Palatal Shrinkage - Tonsillectorny - Traditional Uvulopalatoplasty (RAUP) - Tumors - Tissue in the Uvula/Soft Palate for the Treatment of Snoring - Uvulopaiatopharyngoplasty (UPPP) - Parotidectomy - Radical Neck Disection The Gyrus Somnoplasty TCRF Generator section of the G3 RF Workstation with the Temperature Controlled Radio-frequency (Somnoplasty®) Electrodes is indicated for coagulation of soft tissue including: > The coagulation of enlarged tonsils in patients 13 years of age and older; the reduction of the incidence of airway obstructions, e.g., base of tongue, soft palate, etc., in patients suffering from UARS or OSAS: tissue coagulation in the inferior turbinates; and tissue coagulation in the uvula/soft palate which may reduce the severity of snoring in some individuals. The system is intended for use by qualified medical personnel trained in the use of electrosurgical equipment and familiar with potential complications that may arise during or following fead and Neck surgery.

The Gyrus G3 System Generator has two principal modes of operation: - The monopolar mode has controls for maximum temperature and energy delivered. The unit has readouts for total energy delivered, impedance. temperature for two thermocouples and time of energy delivery. - -The bipolar mode has controls for output waveform type and power. The unit has readouts for set power and waveform. Connectors on the front panel include the monopolar connector for active electrode and dispersive electrode and separate dual bipolar connectors for PlasmaCision electrodes and bipolar instruments. The foot pedal is connected on the back panel. Accessories included with the generator are the electrodes, connector cable, footswitch and a power cable.

The Gyrus Endourology System, when used with a Gyrus Axipolar Resectoscope Electrode, is a radio frequency bipolar electrosurgical device system intended for use in urological surgical procedures involving the ablation or removal of soft tissue and where associated hemostasis is required. The specific urological indications where the system can be used are in transurethral prostatectorny (TURP) for benign prostatic hypertrophy, transurethral incision of the prostate (TUIP) or bladder neck, resection of bladder tumors and in cystodiathermy.

The Axipolar Resectoscope Electrode devices described in this 510(k) are sterile, disposable electrodes designed for use with the Gyrus Endourology System.

Used to permit direct viewing of the cervical canal and the uterine Cavity for the purpose of performing diagnostic and surgical procedures. As used with the Gynecare Versapoint System, the indications for use include: Excision on intrauterine myomas Excision of intrauterine polyps Lysis of intrauterine adhesions Incision of uterine septa When used for resection of endometrial tissue with the G-VAP Electrode, the device is indicated for Endometrial Ablation.

The Gyrus Hysteroscopic Resectoscope that we intend to market employs an electrode specific resectoscope-working element. All other sheaths, etc., are standard COMEG components. A "Quick Connection" feature is used to attach the working element to the sheath. Endoscopic electrosurgical instruments and accessories are described under "Endoscope and Accessories" in 21 CFR 876.1500, and Hysteroscopes and described in 21 CFR 884.1690. The Hysteroscopic Resectoscope is intended to enable the viewing of the cervical canal and the uterine cavity for the purpose of performing diagnostic and surgical procedures. The surgeon performs the examination through the cervical canal. The working elements are the devices that house and control various electrodes and lasers used to remove, cut, coagulate, and transect tissue. The surgeon controls the back and forth movement of the electrode using finger controls. The working elements also house a telescope for visualization. Current is transmitted to the electrode through a high frequency cable. These devices are composed of stainless steel, stainless steel chrome plated, plastic and brass chrome plated parts. The Gyrus Hysteroscopic Resectoscope as cleared in K982771, is identical to the COMEG Resectoscope cleared via K971882, with the working element modified to fit the Gyrus Medical Ltd. electrode. Endoscopic electrosurgical instruments and accessories are described in endoscope and accessories, 21 CFR 876.1500, and endoscope ESU units and accessories are described in 21 CFR 876.4300. Hysteroscopes are described in 21 CFR 884.1690. The Rotating Outer Sheath connection for the working element is of a "snap-on" construction, identical to the cleared device. The principal difference is in the rotating collar which allows 360 degree rotation of the fluid inlet. The Visual Obturator provides the same functionality as the standard obturator facilitating insertion to the uterus. In addition, the Visual Obturator allows use of the hysteroscope (telescope) during insertion, allowing visualization.

The Gyrus Endourology System is comprised of four key components: the Electrode, the Connector Cable, an Axipolar Resectoscope and an electrosurgical generator called the Controller. The Connector Cable connects the Controller to the Electrode. The Electrode is provided in a variety of models, ranging in size from 5 Fr. to 24 Fr. A system specific Resectoscope is provided for use with one of the Electrode models. Other Electrode models are available for use with available cystoscopes with a 5Fr or larger operating channel. The Electrode is supplied sterile and intended for single patient use. The Connector Cable is designed for a number of sterilizations and the Resectoscope for repeat sterilizations using steam autoclaving methods. The Controller is an electronic radio frequency generator. The Gyrus Endourology System is bipolar, incorporating a return electrode as a part of the electrode tip. This means that a return pad is not required for system operation. The return energy in a bipolar device with an integral return electrode does not penetrate the tissue as in a monopolar device. In a monopolar device, the energy passes through the patient's body to reach the return pad.
