DEVICE AND METHOD FOR TREATMENT OF DEEP VEIN THROMBOSIS AND PULMONARY EMBOLISM

An intravascular thrombus retraction device and method utilizing wires compressible into a compact form within a catheter and are self-expandable into a wire mesh web with fluid-penetrable openings in the wire mesh small enough to filter clot particles. A base of the wire mesh web is connected to a radially ring-shaped structure supporting and maintaining an opening in the base of the wire mesh and forming a thrombus capture volume. The ring-shaped structure is compressible into the catheter and is self-expandable when free of compressive forces within the catheter to open up into the open, expanded ring-shaped structure, maintaining the opening in the opening in the base of the wire mesh.
