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 positioned 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, the wire having a sinuous shape in the second configuration and a straighter shape in the first configuration, the wire being rotatable by the motor to enable peaks of the wire in the sinuous shape to contact a wall of the lumen to break up the thrombus or other obstructive material.
