Abstract This disclosure relates to systems, devices, and methods for removing clots, e.g., calcified clots, from a blood vessel and/or for removing a calcified clot from a blood vessel wall. The devices include an elongated tubular body including a wall surrounding a central lumen and having proximal and distal ends. The tubular body includes at least one set of two, three, or more elongated cuts through the wall to form a clot engaging member having two, three, or more ribs between the cuts, wherein a first set of elongated cuts is arranged adjacent to the distal end of the body, and wherein the clot engaging member is made of an elastic material configured to cause the ribs to self-expand radially outwardly from the tubular body when the body is in a non-constrained, deployed configuration. La présente invention concerne des systèmes, des dispositifs et des procédés pour retirer des caillots, par exemple, des caillots calcifiés, d'un vaisseau sanguin et/ou pour retirer un caillot calcifié d'une paroi de vaisseau sanguin. Les dispositifs comprennent un corps tubulaire allongé comprenant une paroi entourant une lumière centrale et comportant des extrémités proximale et distale. Le corps tubulaire comprend au moins un ensemble de deux, trois, ou plus de trois découpes allongées à travers la paroi pour former un élément de mise en prise de caillot comportant deux, trois, ou plus de trois nervures entre les découpes, un premier ensemble de découpes allongées étant agencé en position adjacente à l'extrémité distale du corps, et l'élément de mise en prise de caillot étant constitué d'un matériau élastique configuré pour amener les nervures à s'auto-dilater radialement vers l'extérieur depuis le corps tubulaire lorsque le corps est dans une configuration déployée, non contrainte.
