Claim:
1. A method for removing thrombus in a cerebral artery of a patient comprising: introducing a guidewire into the femoral artery; inserting the guidewire through a vascular system into the cerebral artery; inserting a catheter tube over the guidewire into the cerebral artery; removing the guidewire; placing an introducer at the proximal end of the catheter tube; inserting a thrombectomy wire through the introducer and into the catheter tube, the thrombectomy wire having a core and a component positioned over the core, the component spaced proximally from a distalmost tip of the thrombectomy wire to increase a diameter of the thrombectomy wire in a region spaced from the distalmost tip to increase torsional stiffness of the thrombectomy wire for pushability to the cerebral artery; inserting the thrombectomy wire into the vascular system; advancing the thrombectomy wire to the cerebral artery; operatively connecting the thrombectomy wire to a motor after insertion of the thrombectomy wire into the vascular system, the step of connecting the thrombectomy wire performed by a clinician; and activating the motor to rotate the thrombectomy wire to macerate thrombus in the cerebral artery.
