CA 2468554
An endovascular device assembly (10) includes a delivery member (20) to deliver the assembly endoluminally to an aneurysm, a detachable endovascular device including a thermo-resistive element (30) to deliver heat to the device by passing a first electrical current through the thermo-resistive element, whereupon the device expands to a predetermined shape. The endovascular device is connected to the delivery member by a detachable joint (40), such as an electrolytic sacrificial joint that separates by passing a second electrical current therethrough, to deploy the device within the aneurysm to promote embolization.
L'invention concerne un ensemble à dispositif endovasculaire (10) comprenant un élément de distribution (20) qui permet de céder l'ensemble à un anévrisme par voie endoluminaire. L'invention concerne également un dispositif endovasculaire détachable qui comprend un élément thermo-résistant (30) permettant, lors de l'application d'un premier courant électrique à cet élément thermo-résistant, de délivrer de la chaleur au dispositif endovasculaire qui alors se dilate et prend une forme prédéterminée. Le dispositif endovasculaire est connecté à l'élément de distribution par un joint amovible (40), tel qu'un joint sacrificiel électrolytique, qui se détache lors de l'application d'un deuxième courant électrique et permet de déployer le dispositif endovasculaire dans l'anévrisme en vue de favoriser l'embolisation.
