Abstract
La présente invention concerne des dispositifs et des techniques d'occlusion temporaire qui peuvent être déployés par voie percutanée pour occlure temporairement des vaisseaux sanguins comprenant des vaisseaux sanguins majeurs (par exemple, des artères) ainsi que des artères à l'intérieur d'organes jusqu'à ce que des soins spécialisés puissent être obtenus pour maîtriser chirurgicalement une hémorragie massive suite à un traumatisme civil ou militaire. Les dispositifs d'occlusion temporaire de la présente invention peuvent être utilisés en tant que garrot interne focalisé sur une région ou un vaisseau cible spécifique constituant une variante à un garrot classique pour contrôler un saignement majeur d'une extrémité suite à un traumatisme. Les dispositifs d'occlusion temporaire de l'invention peuvent fournir un procédé plus efficace, fiable et hautement ciblé pour contrôler une hémorragie d'un vaisseau sanguin majeur. En outre, contrairement à un garrot classique, le dispositif d'occlusion temporaire de la présente invention peut être utilisé même en présence d'une lésion de tissu mou.
