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. Scientific studies have shown that tissue trauma may be reduced by using CURIS® 4 MHz radiofrequency technology.*1
CURIS® 4 MHz Technology
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.*2
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 flash. For this reason, the CURIS® 4 MHz radiofrequency generator has two microprocessors for
additional safety and speed.
p3TM, 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.
