Embodiments of the present invention provide medical devices and methods for treating a target site within the body, such as for treating vascular abnormalities. For example, one embodiment provides a stent graft including an occlusive material having a preset, overlapping configuration comprising at least three inverted overlapping layers that are folded over one another. The at least three inverted overlapping layers are configured to be separated and disposed within a catheter in a non-overlapping configuration and return to the preset, overlapping configuration when deployed from the catheter.
La présente invention concerne des dispositifs et des procédés médicaux permettant de traiter un site cible au sein de l'organisme, comme des anomalies vasculaires. Un mode de réalisation concerne, par exemple, une endoprothèse comprenant un matériau occlusif présentant une configuration prédéfinie chevauchante comportant au moins trois couches inversées chevauchantes qui sont repliées l'une sur l'autre. Lesdites trois couches inversées chevauchantes sont conçues de façon à pouvoir être séparées et disposées à l'intérieur d'un cathéter selon une configuration non chevauchante, puis à pouvoir revenir à leur configuration prédéfinie chevauchante suite à leur déploiement hors du cathéter.
