The apparatus for deployment of a therapeutic device such as a micro- coil provides for a pusher member and a connector fiber for securing the therapeutic device to the pusher member. The connector fiber passes adjacent to a distal heating end of an elongated, flexible heat pipe member within the distal portion of the pusher member, for heating and breaking the connector fiber to release the therapeutic device when a desired placement of the therapeutic device within the vasculature is achieved.

L'invention concerne un appareil permettant le déploiement d'un dispositif thérapeutique, tel qu'une micro-spirale. Cet appareil comprend un élément pousseur (142) et une fibre d'assemblage (162) servant à attacher le dispositif thérapeutique (144) à l'élément pousseur. Cette fibre d'assemblage passe à proximité d'une extrémité chauffante distale (166) d'un élément thermique flexible allongé (168) à l'intérieur de la partie distale de l'élément pousseur. Ledit élément thermique est conçu pour chauffer et faire rompre la fibre d'assemblage, de manière à libérer le dispositif thérapeutique une fois que ce dernier a été mis en place de la façon souhaitée à l'intérieur de la vasculature.
