Rotational thrombectomy wire

1. A rotational neurovascular thrombectomy wire for breaking up vascular thrombus or other obstructive material in a cerebral artery, the thrombectomy wire comprising a core having a proximal portion and a distal portion, a cable extending distally of the core and a hypotube coupling the cable to the core, the cable having a first diameter and the hypotube having a second diameter greater than the first diameter, at least a first covering material positioned over the cable to provide a smoother transition from the hypotube to the cable and increase the stiffness of the cable, the wire insertable into the cerebral artery and rotatable by a motor to macerate cerebral clots or other obstructive material in the cerebral artery.

2. The neurovascular thrombectomy wire of claim 1 , further comprising a second covering material over the first covering material.

3. The neurovascular thrombectomy wire of claim 2 , wherein the second covering material comprises a polymer jacket.

4. The neurovascular thrombectomy wire of claim 2 , wherein the cable has a third covering material.

5. The neurovascular thrombectomy wire of claim 4 , the third covering material is positioned between the cable and the second covering material.

6. The neurovascular thrombectomy wire of claim 4 , wherein a distal coil is positioned over a distal end of the cable, and the third covering material terminates proximal of the distal coil.

7. The neurovascular thrombectomy wire of claim 2 , wherein a distal coil is positioned over a distal end of the cable, and the second covering material extends over the distal coil.

8. The neurovascular thrombectomy wire of claim 1 , further comprising a first coil positioned over the distal portion of the core to increase rigidity for pushablility through the cerebral artery.

9. The neurovascular thrombectomy wire of claim 1 , wherein the core has a tapered region at a section coupled to the hypotube so the hypotube is positioned over the tapered region.

10. The neurovascular thrombectomy wire of claim 9 , further comprising a first coil positioned over the distal portion of the core to increase stiffness of the wire.

11. The neurovascular thrombectomy wire of claim 10 , wherein the first coil is positioned proximal of the hypotube.

12. The neurovascular thrombectomy wire of claim 1 , wherein a distal coil is positioned over a distal end of the cable, a distal portion of the wire including the distal coil having a sinuous shape.

13. The neurovascular thrombectomy wire of claim 1 , wherein the first covering material comprises a polymer jacket.

14. The neurovascular thrombectomy wire of claim 1 , wherein a proximal portion of the cable is stiffer than a distal portion of the cable.

15. A rotational neurovascular thrombectomy wire for breaking up vascular thrombus or other obstructive material in a cerebral artery, the thrombectomy wire comprising a core having a proximal portion and a distal portion, a cable extending distally of the core and a hypotube coupling the cable to the core, the wire insertable into the cerebral artery and rotatable by a motor to macerate cerebral clots or other obstructive material, the wire having a sinuous portion to create a wave pattern upon rotation to macerate thrombus within the cerebral artery.

16. The neurovascular thrombectomy wire of claim 15 , wherein the cable has a first diameter and the hypotube has a second diameter greater than the first diameter.

17. The neurovascular thrombectomy wire of claim 15 , wherein the sinuous portion is movable from a straighter delivery position to a second position to expose the sinuous portion within the cerebral artery.

18. The neurovascular thrombectomy wire of claim 17 , further comprising a coil at a distal tip portion of the wire.
