Fig. 1 (57) Abstract: A clot removal device has a segment that has two main struts that serve as a frame for holding a plurality of secondary c:j= struts. Each of the two main struts has a proximal end that is connected at a proximal point of the segment and extends along a gener-11.                                                                           ally circumferential path, with each main strut terminating at a separate connecting point that is distal from the proximal point. The VZ+ ot connecting points are connected to each other to form a generally tubular structure defining an inner lumen. The plurality of secondary " struts forms a lattice of cells, with each cell surrounded by four secondary struts. Two generally straight distal struts are connected to k the lattice of cells at a distal end of the segment, and are connected to each other to form a distal point. A distal opening is defined by 00 the cells adjacent the distal struts, the distal opening communicating with the lumen and terminating at the proximal point. o e=1 [Continued on nextpagd Date Reçue/Date Received 2021-04-15
