4 MHz Technology
The higher the frequency, the less the resistance of biological tissue to electromagnetic fi elds – up to the point where the cell membranes are capacitively coupled.
This is exactly what happens with the 4 MHz produced by the CURIS® (both in the monopolar and the bipolar modes).
The electromagnetic fi elds are active in the tissue cells –not, as is the case with conventional electrosurgical units, between the cells.
As a result energy is administered gently and in a highly focused fashion. For example precise monopolar cuts are possible while lateral heat damage is reduced.
Conventional electrosurgical units: The electromagentic fi eld concentrates between the cells and heats up only the outer layer.   CURIS® 4 MHz: Cell membranes are conductive and the energy is absorbed evenly inside the cells. The result are highly focussed tissue effects.

p3TM is active in all coagulation modes of the CURIS®. 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. Highly-focussed, yet gentle coagulation with minimal thermal damage is possible. The p3TM process is, of course also, AutoRF ™ controlled.

Precision thanks to AutoRF™
The AutoRF ™ function 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 ™ the CURIS® 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.
RaVoR™-Mode: The pulsed power output with short intervals between the individual packages gives enough time for the coagulated tissue to absorb the applied energy.   Monopolar cutting: Sections 1 to 5 show the different kinds of tissues and cutting speeds to which the unit adjusts its power output automatically.
