MECANISME DE DETACHEMENT D'UNE SPIRE METALLIQUE POUR EMBOLISATION AVEC ELEMENT DISTAL SOUPLE, ELEMENT ELECTRIQUE CHAUFFANT RESISTIF ET ELEMENT EN POLYMERE A MEMOIRE DE FORME
An embolic coil detachment system includes an elongated, flexible shape memorypolymer tube having an inner wall surface defining an interior lumen. A distalportion of theshape memory polymer tube has an enlarged and reduced diameter configurations.An emboliccoil is releasably mounted to the shape memory polymer tube by a headpiecereleasably attachedwithin a distal portion of the shape memory polymer tube. A resistive heatingelement disposedlongitudinally along and in immediate contact with the inner wall surface ofthe distal tubularwall of the shape memory polymer tube provides direct, even heating to releasethe headpieceand embolic coil attached thereto when the resistive heating element isenergized.
