Clot retrieval device for ischemic stroke treatment

A clot removal device, comprising a plurality of segments that includes at least a first segment, a second segment and a third segment, each segment having two main struts that serve as a supporting frame that is connected to a plurality of secondary struts, wherein:

• the plurality of secondary struts form a lattice of cells for each segment;
• the two main struts of the first segment having proximal ends that are connected to each other at a proximal point of the first segment, and distal ends terminating at separate first segment connecting points that are distal from the proximal point, with the first segment connecting points being connected to each other to form a generally tubular structure defining an inner lumen for the first segment;
• the two main struts of the second segment having proximal ends, each being connected to a separate one of the distal ends of the two main struts of the first segment at the first segment connecting points, and the main struts of the second segment also having distal ends that are connected to each other in the second segment;
• and
• the two main struts of the third segment having proximal ends that are connected to each other at a proximal point of the third segment, and to the distal ends of the two main struts of the second segment, the two main struts of the third segment also having distal ends terminating at separate third segment connecting points that are distal from the proximal point, with the third segment connecting points being connected to each other to form a generally tubular structure defining an inner lumen for the third segment;
• wherein the clot removal device is delivered to a location at or adjacent to a clot or embolus in the blood vessel, and the plurality of segments are expanded at or adjacent the location of the clot or embolus.
