Abstract
A clot retrieval device, for example to be used in a thrombectomy, is provided including a catheter, an elongated member, and a knitted basket with a proximal end coupled to the catheter and a distal end coupled to the elongated member. The elongated member is movable between an expanded position and a compressed position relative to the catheter and is configured so that the knitted basket expands radially and compresses as the elongated member is moved to the compressed position. The knitted basket is comprised of a plurality of wires coupled together by a plurality of windings. Each winding comprises one of the plurality of the wires twisted about another of the plurality of wires.
