Sutter CURIS

Sutter CURIS RFThe CURIS® radiofrequency generator with tissue impedance control offers ultra-high frequency leading to lower tissue impedance, allowing incision and coagulation at lower power settings resulting in less thermal damage. The higher the frequency, the less the resistance of biological tissue to electromagnetic fields – up to the point where the cell membranes are capacitively coupled. The electromagnetic fields are active in the tissue cells and not, as is the case with conventional electrosurgical units, between the cells. As a result, energy is administered gently and highly focused.

Highly-focussed, yet gentle coagulation with minimal thermal damage is possible. Radiofrequency energy is delivered in small packages of about 50 per second. Due to the pulsed power output, there are very short breaks between the individual packages. The tissue has the time to absorb and distribute the energy and will generally be less traumatised.


AutoRF is the main control feature of the CURIS. It responds to tissue impedance in all modes and controls, and adjusts the power output according to tissue resistance. AutoRF will tailor the energy output (if need be even cut off or drive to the chosen maximum) in order to ensure reproducible surgical results while cutting or coagulating.


Histological evaluations in peer-reviewed journal articles confirm that CURIS RF-induced incisions create signifi cantly less thermal damage and that wound healing is faster.¹
