The invention provides: 1. A system for retrieving vascular debris in a vasculature comprising: at least three segments (52, 56) expandable from a collapsed state to an expanded state, each of the at least three segments having (a) a waist comprising a radially largest region of the segment and (b) two longitudinal ends; at least two intermediate portions (54a,b), each of the at least two intermediate portions comprising a pivot that connects adjacent segments, each pivot having a diameter less than a diameter of the waist; a sheath (144) configured to encase the at least three segments in the collapsed state; and a tether (140) attached to a proximalmost of the at least three segments and configured to position the at least three segments relative to the sheath; wherein each of the at least three segments comprises at least two struts that extend from a proximal end to a distal end of the segment; and each of the at least two struts extends from a proximal end of the segment and divides into at least two sub-struts at the waist, with each of the two sub-struts connecting to a circumferentially adjacent strut extending from the distal end of the segment. L'invention concerne un dispositif de thrombectomie à plusieurs pivots utilisé pour saisir et récupérer des débris vasculaires. Le dispositif comprend au moins deux segments extensibles radialement, pouvant passer d'un état écrasé à un état dilaté, chacun desdits segments ayant (a) un étranglement comprenant une zone radialement plus large du segment et (b) deux extrémités longitudinales ; au moins une partie intermédiaire, chacune desdites parties intermédiaires comprenant un pivot reliant des segments adjacents, chaque pivot ayant un diamètre inférieur au diamètre de l'étranglement ; un lien attaché à la partie la plus proximale desdits segments et conçu pour positionner lesdits segments ; chacun desdits segments comprend au moins deux jambes s'étendant longitudinalement depuis une extrémité pr
