Claim:
A medical device for clot removal from small vessels by fibrinolytic infusion or vacuum retrieval, the device comprising: an elongated tubular delivery member having a proximal portion and a distal portion, the delivery member comprising a metal core of multiple shaped-wire strands having an A-side and a B-side, the wire strands helically wound to form a lumen with an inner diameter defined by the A-side of the strands and a polymer overlay disposed about the metal core; the proximal portion and distal portion being different in their predetermined degree of rigidity; and a leak-free connector in contact with the proximal portion of the delivery member; the connector being compatible for use with fibrinolytic infusion and vacuum retrieval; wherein the helically wound wire strands form a first polygon defined by the B-side of the strands and a second polygon defined by the A-side of the strands; the second polygon defining the shape of the lumen.
