CURIS® 4 MHz Radiofrequency Generator
One unit – many applications
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.
Scienti c studies have shown that tissue trauma may be reduced by using CURIS® 4 MHz radiofrequency technology.*
CURIS® 4 MHz Radiofrequency Technology
The higher the frequency, the less the resistance of biological tissue to electromagnetic elds –
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 eld 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*

Precision thanks to AutoRF ™
AutoRF™ is a smart impedance control function that will tailor the power output of the CURIS® 4 MHz radiofrequency generator to the tissue condition. Whether it is cutting through different types of tissue (such as
mucosa, muscle, fat or connective tissue) or altering tissue conditions during coagulation, the AutoRF™
feature will deliver adapted power output as required by the different tissue impedance.
When dissecting different types of tissue in one cut (skin, fat, muscles), the unit has to process and
respond to the AutoRF™ data in a ash. For this reason, the CURIS® 4 MHz radiofrequency generator has
two microprocessors for additional safety and speed.

, which stands for pulsed power performance, is active in all coagulation modes of the CURIS® 4 MHz
radiofrequency generator. Radiofrequency energy is delivered in about 50 small packages per second.
Due to the pulsed power output, there are short breaks between the individual packages, giving the tissue
enough time to absorb the energy. Highly focused, yet gentle coagulation with minimal thermal damage is
possible.

technology, appears to have promising results for patients with snoring
and mild OSA. One treatment session resulted in signi cant reduction
in snoring intensity, improvement in sleep quality and QOL, and reduction
in daytime sleepiness.“

RaVoRTM Radiofrequency Volume Reduction
RaVoR™ of the inferior turbinates, soft palate, tongue base, etc. is an interstitial application
for submucosal tissue shrinkage. Precise delivery of energy and smart power adjustment depending
on actual tissue impedance aid in creating consistent and repeatable lesions. As soon as the
right size of a lesion has been achieved, the CURIS® 4 MHz radiofrequency generator will automatically stop the activation (AUTO STOP mode), and give an acoustic signal. 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.
Audio Feedback
If desired, an acoustic feedback function (AUDIO FEEDBACK) can be activated. While a lesion is
created in RaVoR™ mode, the change in tissue condition is signaled by a changing pitch: The further
the lesion progresses, the higher the activation sound. This mode may also be used to potentially
increase the patient’s comfort. The patient will be able to listen and follow what happens inside the tissue.
