The CURIS 4 MHz radiofrequency generator relies on innovative 4 MHz technology: It is gentle to the tissue and effective for coagulation, for submucosal shrinkage, and for cutting. Scientific studies have shown that tissue trauma may be reduced by using CURIS 4 MHz radiofrequency technology.*1 The higher the frequency, the less the resistance of biological tissue to electromagnetic fields – up to the point where cell membranes are capacitively coupled. This effect is created by the CURIS 4 MHz radiofrequency generator in all monopolar and bipolar modes. When using conventional electrosurgical units the electromagnetic field concentrates between the cells and only heats up the outer layer. However, with the CURIS 4 MHz radiofrequency generator cell membranes are conductive, and energy is absorbed evenly inside the cells. As a result, energy is administered gently and in a highly focused fashion. Precise monopolar cuts are possible while lateral heat damage is kept to a minimum.
RaVoR™ (Radiofrequency Volume Reduction) is an interstitial application for submucosal tissue shrinkage. Radiofrequency energy causes deliberate local lesions through the short and selective heating of certain tissue areas. The treated tissue is decomposed by the body‘s own immune system and transformed into fibrous scar tissue. This process leads to a shrinkage and stiffening of the treated area. Sutter has developed different bipolar electrodes for the treatment of sleep-related breathing disorders based on the anatomical sites of obstruction.
RaVoR™ Bipolar Electrodes: Advantages
Instrument's shape follows the anatomy
The shape of the RaVoR™ bipolar electrodes follow the anatomy, thus allowing easy access to the application site, giving optimal view and perfect control over the instrument.
Ideal lesions
RaVoR™ bipolar electrodes make oval-shaped, long lesions possible. Both shape and size allow treating a bigger area while protecting bony structures as well as mucosa.
Protecting mucosa
A thin insulating layer protects the surface of the mucosa from thermal damage.
Autoclavable and reusable
RaVoR™ bipolar electrodes can be cleaned and autoclaved, just like conventional surgical instruments.
RaVoR™ of the inferior turbinates has become a standard treatment option in sleep surgery, i.e. to treat habitual snoring, mild sleep apnea and to increase both comfort and compliance of CPAP treatment. Moreover, it can be beneficial to improve nasal breathing, even together with septum correction, or to treat symptoms of rhinitis.
RaVoR™ (Radiofrequency Volume Reduction) of the soft palate has become the standard surgical procedure to treat habitual snoring and mild sleep apnea. Multiple clinical studies confirmed the efficacy and the clinical benefit of the treatment (see abstracts). This minimally invasive treatment method preserves the structures and function of the soft palate. RaVoR™ is performed under local anesthesia; it can easily be combined with other treatments, e.g. RF-UPPP or CPAP treatment.
RaVoR™ of the tongue base is intended for patients suffering from light to moderate obstructive sleep apnea and retrolingual obstruction. RaVoR™ (Radiofrequency Volume Reduction) of the tongue base is a minimally invasive surgical treatment option for obstructions on that level. Tongue base reduction is usually combined with either conservative treatment (CPAP) or other surgical interventions (multi-level). RaVoR™ of the tongue base is performed under general anesthesia. Patients remain under supervision for at least one night.
