VASCULATURE DEVICE

摘要

A vasculature device with a wire with a shaped set portion, an electrically conductive path, an electrical connector connecting the wire to the electrically conductive path at a point distal to the shaped set portion, and a hypotube encasing the wire, electrically conductive path and electrical connector is provided. The vasculature device can be actuated from a low-profile configuration to a deployed configuration by heating of the wire, and in particular the shaped set portion of the wire, via application of an electrical current to the wire. The vasculature device is useful in removal of clots, thromboemboli and foreign bodies from the vasculature, and in particular the cerebral vasculature, and as steering wires or guidewires.
