Abstract
L'invention concerne une méthode de régulation de l'expression génique d'un patient par la circulation contrôlée d'une matière d'oligonucléotide antisens (ASO) à travers un circuit de fluide fermé formé entre le ventricule du patient et les régions lombaires. À cet effet, après le couplage d'un canal de fluide entre ces régions, de tels modes de réalisation ajoutent de l'ASO au canal de fluide (de préférence après que le canal a été amorcé avec du CSF) et activent une pompe pour faire circuler de manière contrôlée le CSF et l'ASO mélangé au CSF. Le flux de fluide CSF/ASO peut être géré pour localiser un traitement (par exemple, fournir une distribution cérébrale profonde) tout en réduisant au minimum la toxicité potentiellement provoquée par l'ASO vers certains nerfs (par exemple, le nerf périphérique).
