Stereoelectroencephalography (SEEG)

SEEG using depth electrodes allows the identification of epileptogenic zones for tailored resection surgery in patients with refractive epilepsy.

How can we help?

We have products that will not only reduce time taken to implant multiple electrodes, but also plan these trajectories. Renishaw can also supply the SEEG electrodes and accessories required for the procedure.

In SEEG we place up to 20 intracerebral electrodes in order to identify the epileptogenic zone and map eloquent structures. Thanks to the use of the neuromate system, every target can be reached with a combination of speed and sub-millimetric accuracy.

The Renishaw robot is a significant step forward for epilepsy surgery in Wales. The increased accuracy and reduced operating time using neuromate® for intracranial electrode placement, enables us to investigate and treat even the most complex cases, to achieve seizure freedom for our patients.
