Abstract

L'invention concerne des méthodes, des dispositifs et des matériaux pour la formation in situ d'un implant pour le traitement d'un nerf. Un site de traitement est positionné à l'intérieur d'une cavité définie par une forme. Un support transformable est introduit dans la cavité pour entourer le site de traitement. Le support subit une transformation et passe d'un état relativement fluide à un état relativement non fluide pour former une barrière protectrice entourant le site de traitement. Le milieu hydrophile coopère avec la surface hydrophobe de la cavité pour faciliter la libération rapide de l'implant de la cavité après la transformation. L'implant peut être un capuchon de nerf inhibant la croissance pour inhiber la formation de névromes suite à une lésion nerveuse planifiée ou traumatique, un conduit permettant la croissance pour faciliter la reconnexion d'un nerf sectionné, ou un ancrage pour stabiliser une électrode de gestion de la douleur par rapport à un nerf. L'accès au site de traitement des nerfs peut être un accès chirurgical ouvert ou par voie percutanée.
