New Generation Combined SEEG / RFA Electrodes

The latest generation of SEL-4XX series of deep thermal coagulation brain electrodes newly developed by Rishena Medical is the first SEEG electrode in the market, that has dual functions of localized diagnosis and minimally invasive treatment.

?

(1) Detecting deep EEG signals, with all the characteristics of traditional deep electrodes and positioning diagnosis functions

?

The precise location of epileptic focus is the fundamental prerequisite for epilepsy resection. Traditional scalp EEG can only record potential changes in the cortex 1 / 5-1 / 10. Cortical EEG is also a process of inferring three-dimensional lesions from two-dimensional surfaces, but it is still difficult to record and accurately locate deep or smaller lesions positioning.

?

Stereotactic electroencephalography (SEEG) is a revolutionary leap in epilepsy electrophysiological diagnosis and positioning technology by directly implanting deep electrodes into suspicious lesions in the brain to accurately detect the origin and conduction distribution of epilepsy.

?

(2) Built-in temperature sensor probe, can perform RF thermal condensation damage under precise temperature control

?

Traditional deep electrodes only have the function of electrophysiological localization diagnosis. Secondary craniotomy is needed during surgical treatment, which increases the patient's pain and treatment risk.

?

The SEEG developed by Rishena has a built-in high-sensitivity temperature sensor, which is stable and reliable for small epilepsy lesions with controlled temperature under closed-loop thermocoagulation, with less damage and controllable thermal plaque.
