Abstract

The designs and methods disclosed herein are for a clot retrieval catheter that can have a proximal elongate body with a large bore lumen and a distal tip expandable to a diameter larger than the outer sheath through which it is delivered. The distal tip can have a flexible metallic support frame to provide radial scaffolding and the ability for further flexible expansion when ingesting a clot. The support frame can be designed so that the expanding movement is focused in a portion of the circumference though a plurality of deformable cells that can collapse to be almost flat and parallel to the longitudinal axis for deliverability, but expand to a very steep angle for good resistance to collapse under aspiration. The designs can be sufficiently flexible to navigate tortuous anatomy but recover to maintain the inner diameter of the lumen when displaced in a vessel.
