Abstract:
1. A thrombectomy apparatus for breaking up thrombus or other obstructive material in a lumen of a vascular graft or vessel, the apparatus comprising: a flexible sheath extending in an axial direction; a wire slidable within the flexible sheath; and a motor operatively connected to the wire; the wire and the flexible sheath being relatively movable in the axial direction so that the wire has a first configuration when positioned within the flexible sheath and a second configuration when deployed from the flexible sheath, in the second configuration the wire having a first arcuate region extending in a first direction transverse to the axial direction and a second arcuate region spaced in the axial direction from the first arcuate region and extending in a second direction transverse to the axial direction, the wire being rotatable by the motor so that the first and second arcuate regions break up the thrombus or other obstructive material in the lumen.
