Rotational thrombectomy wire
First Claim
Patent Images
1. A method for removing thrombus in a cerebral artery of a patient comprising:
- introducing a guidewire and a first catheter into the femoral artery;
advancing the first catheter through the vascular system;
removing the guidewire;
providing a housing and a second catheter extending distally from the housing;
providing an introducer sheath;
inserting a rotational thrombectomy wire through the introducer sheath and through the second catheter;
connecting the introducer sheath to the housing;
advancing the thrombectomy wire within the second catheter to access the cerebral artery;
subsequent to advancing the thrombectomy wire within the second catheter operably coupling a motor to the proximal end of the thrombectomy wire; and
activating the motor to rotate the thrombectomy wire to macerate thrombus in the cerebral artery.

Abstract
A rotational thrombectomy wire for breaking up vascular thrombus or other obstructive material having a core having a proximal region and a distal region and being rotatable by a motor. The distal region has a smaller diameter than the proximal region. A cable is coupled to the distal region of the core and extends distally thereof. A torque tube is positioned over the cable and a coil is positioned over a distal portion of the cable. A distal portion of the cable has a non-linear configuration. A first covering material is positioned over the coil.
