The CURIS 4 MHz radiofrequency generator relies on innovative 4 MHz radiofrequency technology. Scientific studies have shown that tissue trauma may be reduced by using CURIS 4 MHz radiofrequency technology.1


CURIS® 4 MHz Radiofrequency Technology

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. 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


p3 Technology

p3 is active in all coagulation modes of the CURIS 4 MHz radiofrequency generator. 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 the energy.


Precision thanks to AutoRF

The AutoRF function is a key control feature of the CURIS 4 MHz radiofrequency generator. It responds to tissue impedance in all modes and adjusts the power output according to tissue resistance in certain modes. AutoRF will tailor the energy output (will cut off if needed or increase to the chosen maximum) in order to help achieve reproducible surgical results while cutting or coagulating.

CURIS® Information Video




“The CURIS 4 MHz radiofrequency generator provides unparalleled precision to the neurosurgeon seeking
optimal control in neurosurgical cases. I have used the device for surgery in the cavernous sinus, resection of cavernous malformations from the motor cortex, minimally invasive clipping of anterior communicating artery aneurysm, and resection of acoustic neuroma. I have found the ability to perform pinpoint cautery, with minimal thermal and electrical spread, increases the safety and efficacy of my operations.”
