Thermolesion with the Neuro N50

Interventional pain therapy uses minimally invasive procedures such as thermolesion or cryotherapy with the aim of achieving a prolonged reduction of chronic pain through selective disruption or modification of the pain pathways of the affected nerves. This is carried out either by targeted drug injections or the interruption of pain transmission by minimally invasive neurodestructive procedures (e.g. thermolesion).

As an example, chronic pain >> within facet joint syndrome can be treated accurately, effectively and safely with the proper indications using radio frequency thermolesion.

The Neuro N50 radiofrequency generator for thermolesion is the centerpiece of temperature-controlled RF thermolesion treatment. The programmed temperature control allows controlled lesion techniques to be performed so that the volume of the thermolesion can be determined and reproduced. All functional processes are monitored by the device, thereby providing maximum safety and comfort for both the user and patient during thermolesioning. Only the coagulation temperature and duration can be pre-set, while all additional functions are automatically managed and regulated by the N50 (including the dose of the HF power).
