1. A thrombectomy device comprising:
a cylindrical proximal portion forming a stent frame having an outer lattice network of an outer plurality of interconnecting segments with no elongate central member extending longitudinally along a central axis of the stent frame, the outer plurality of interconnecting segments being configured to exert a radial force against an inner wall of a blood vessel; and
an at least one radiopaque segment comprising three radiopaque wires engaged with the stent frame in a circumferentially spaced apart arrangement, the three radiopaque wires of the at least one radiopaque segment radially extending inwardly from the stent frame and converging to form a singular, free-standing radiopaque tip positioned substantially on the central axis of the stent frame.
