Devices and methods for electrode implantation. A first embodiment includes an electrode insertion tool adapted to tunnel through tissue and attach, at its distal end, to a lead, such that the lead may be pulled into the tunneled space as the electrode insertion tool is removed. Additional embodiments include methods for inserting electrode/lead assemblies, including a method wherein an insertion tool is first used to tunnel through tissue, then to pull an electrode/lead into the tunneled space. In a further embodiment the insertion tool is next used, with a splittable sheath disposed thereon, to create an additional path into tissue, after which the insertion tool is removed, leaving the sheath in place; a lead is inserted to the sheath, and, finally, the splittable sheath is removed over the lead.

La présente invention décrit des dispositifs et des procédés d'implantation d'électrode. Un premier mode de réalisation comprend un outil d'insertion d'électrode permettant de passer en tunnel sous les tissus et d'attacher un fil à une extrémité distale ; le fil doit pouvoir être tiré dans l'espace du tunnel lorsque l'on retire l'outil d'insertion d'électrode. D'autres modes de réalisation comprennent des procédés d'insertion de montages électrode/fil, y compris un procédé par lequel un outil d'insertion est d'abord utilisé pour passer en tunnel sous les tissus, puis pour tirer une électrode/un fil dans l'espace de tunnel. Dans un autre mode de réalisation, l'outil d'insertion est ensuite recouvert d'une gaine divisible, pour créer un nouveau parcours dans les tissus, après quoi l'on retire l'outil d'insertion, en laissant la gaine en place ; un fil est inséré dans la gaine et la gaine divisible est ensuite retirée le long du fil.
