Abstract
The present invention pertains to a thrombectomy device comprising a cylindrical proximal portion and one or more radiopaque segments. The cylindrical proximal portion forms a stent frame having an outer lattice network of an outer plurality of interconnecting segments. The outer plurality of interconnecting segments are configured to exert a radial force against an inner wall of a blood vessel. The radiopaque segment is formed from a plurality of radiopaque wires extending from the outer stent frame to a central axis of the thrombectomy device along a length of the stent frame. The radiopaque segment converges to a tip along with the central axis.
