Abstract
A rotatable thrombectomy wire for breaking up thrombus or other obstructive material comprising an inner core composed of a flexible material and an outer wire surrounding at least a portion of the inner core. The outer wire has a sinuous shaped portion at a distal region. The inner core limits the compressibility of the outer wire. The outer wire is operatively connectable at a proximal end to a motor for rotating the wire to macerate thrombus.

1-14. (canceled)
A thrombectomy apparatus for breaking up thrombus or other obstructive material comprising a handle, a sheath, a battery, a motor powered by the battery, and a sinuous thrombectomy wire having first and second outer wires wound to form a coil, a blunt polymeric tip, a metal tip for connecting the polymeric tip, and an inner core composed of a material to limit the compressibility of the coil, at least at a distal tip turns of the first wire occupy the space between adjacent turns of the second wire forming a closed pitch, the coil having a sinuous portion and surrounding at least a distal region of the inner core, the inner core having a sinuous portion within the sinuous portion of the coil, the sinuous portion of the inner core and the coil movable from a straighter configuration within the sheath for delivery to a sinuous configuration when exposed from the sheath, a portion of the metal tip extending between the outer wires and the polymeric tip.
