Abstract

La présente invention concerne les systèmes pour extraire la substance thromboembolique St présente dans un vaisseau sanguin Vs. Le système se caractérise essentiellement par le fait qu'il comporte un stent 30 formé d'au moins un fil 35 agencé en spirale formant un manchon Mn apte à prendre une forme repliée instable Fr dans laquelle il a une dimension transversale d'une première valeur donnée et une forme dépliée stable Fd dans laquelle il a une dimension transversale d'une seconde valeur donnée supérieure à la première, des moyens pour introduire le stent dans le vaisseau sanguin et commander son passage de sa forme repliée à sa forme dépliée, et une couche 40 d'un produit adhérant à la fois à la surface latérale du fil 35 et à la substance thromboembolique St, la couche étant déposée sur une partie 36 de la surface latérale d'au moins une partie de la longueur du fil 35.The present invention relates to systems for extracting the thromboembolic substance St present in a blood vessel Vs. to assume an unstable folded shape Fr in which it has a transverse dimension of a first given value and a stable unfolded shape Fd in which it has a transverse dimension of a second given value greater than the first, means for introducing the stent in the blood vessel and controlling its passage from its folded shape to its unfolded shape, and a layer 40 of a product adhering both to the side surface of the thread 35 and to the thromboembolic substance St, the layer being deposited on a portion 36 of the side surface of at least part of the length of the wire 35.
