Publications

Nos produits sont utilisés dans le monde entier dans les soins quotidiens aux patients, ainsi que dans la recherche sur des techniques et des thérapies innovantes.

En collaboration avec des médecins et des scientifiques, nous développons de nouvelles idées dans les domaines du neuromonitoring per-opératoire, de la neurochirurgie fonctionnelle et du traitement de la douleur.

Aujourd'hui et à l'avenir, nous nous concentrons sur la sécurité des patients.
