An implant for treating brain aneurysms, especially terminal aneurysms, comprises a neck cover and elongate shaft removably secured to an embolic delivery catheter. As such, the shaft aids in directing and placing the cover at the aneurysm neck, protecting the delivery catheter from adhesion with the embolic material, and securing the cover in place with connection or adhesion of the shaft to the embolic material delivered through the catheter. The implant can be anchored at the aneurysm either by interface and/or adhesion of the shaft or shaft and cover with the resident embolic materials.

La présente invention concerne un implant pour le traitement d'anévrismes cérébraux, notamment des anévrismes terminaux, comportant un dispositif de coiffe du col et une tige de forme allongée solidaire d'un cathéter d'implantation d'agents emboliques. Ainsi, la tige aide à orienter et placer le dispositif de coiffe au niveau du col d'anévrisme, protégeant le cathéter d'implantation contre une adhésion à la matière embolique, et fixant le dispositif de coiffe en place avec la connexion ou l'adhésion de la tige à l'agent embolique administrée à travers le cathéter. L'implant peut être ancré au niveau de l'anévrisme soit par contact et/ou par adhésion de la tige ou de la tige et du dispositif de coiffe avec les agents emboliques contenus.
