Title (EN) THROMBECTOMY DEVICES AND TREATMENT OF ACUTE ISCHEMIC STROKE WITH THROMBUS ENGAGEMENT
(FR) DISPOSITIFS DE THROMBECTOMIE ET TRAITEMENT D'UN ACCIDENT VASCULAIRE CÉRÉBRAL ISCHÉMIQUE AIGU AVEC IMPLICATION D'UN THROMBUS
Abstract:
(EN) Components and corresponding systems are described for providing removal of a clot or fragment thereof to address an acute ischemic stroke condition. In particular, a filter design is presented that provides metal elements below a bundle of polymer fibers to provide more mechanical strength while cushioning the vessel wall from direct contact with the metal elements. Designs of stent retrievers are presented with polymer covers or mounted on the exterior of a microcatheter. Corresponding systems are described that can use various combinations of the components, generally in combination with an aspiration catheter. Corresponding procedures are described that can effectively use the various devices and systems.
(FR) L'invention concerne des composants et des systèmes correspondants permettant le retrait d'un caillot ou d'un fragment de caillot pour traiter un accident vasculaire cérébral ischémique aigu. En particulier, l'invention concerne un modèle de filtre qui comprend des éléments métalliques en dessous d'un faisceau de fibres polymères pour conférer plus de résistance mécanique tout en amortissant le contact direct des éléments métalliques avec la paroi vasculaire. L'invention concerne des modèles d'extracteur d'endoprothèse munis de couvertures polymères ou montés sur l'extérieur d'un microcathéter. L'invention concerne des systèmes correspondants qui peuvent utiliser diverses combinaisons des composants, généralement en combinaison avec un cathéter d'aspiration. L'invention concerne également des procédés correspondants qui peuvent utiliser de façon efficace les divers dispositifs et systèmes.
