Abstract

A rotatable thrombectomy wire for breaking up thrombus or other obstructive material including an inner core composed of a flexible material and an outer wire surrounding at least a portion of the inner core. The outer wire has a sinuous shaped portion at a distal region. The inner core limits the compressibility of the outer wire. The outer wire is operatively connectable at a proximal end to a motor for rotating the wire to macerate thrombus.

Claims (16)

1. A thrombectomy apparatus for breaking up thrombus or other obstructive material comprising a handle, a sheath, a battery, a motor powered by the battery, and a sinuous thrombectomy wire having first and second outer wires wound to form a coil, a blunt elongated flexible tip, a metal tip for connecting the flexible tip to the coil, and an inner core composed of a material to limit the compressibility of the coil, at least at a distal tip turns of the first wire occupy a space between adjacent turns of the second wire forming a closed pitch, the coil having a sinuous portion and surrounding at least a distal region of the inner core, the inner core having a sinuous portion within the sinuous portion of the coil, the sinuous portion of the inner core and the coil movable from a straighter configuration within the sheath for delivery to a sinuous configuration when exposed from the sheath wherein a portion of the metal tip extends over the outer wires, the metal tip extending distally for a first distance from a distal end of the coil, and the flexible tip is positioned over the metal tip and extends distally therefrom a second distance, the second distance exceeding the first distance.

2. The thrombectomy apparatus of claim 1 , wherein the distal end of the coil formed by the outer wires is non-tapered.

3. The thrombectomy apparatus of claim 1 , wherein the metal tip includes a dumbbell shape.

4. The thrombectomy apparatus of claim 1 , wherein the flexible tip is injection molded over the metal tip.

5. The thrombectomy apparatus of claim 4 , wherein the metal tip has a dumbbell shape and the flexible tip is injection molded over the dumbbell shape of the metal tip.

6. The thrombectomy apparatus of claim 1 , wherein the inner core has a diameter to fill an inside of the coil.

7. The thrombectomy apparatus of claim 1 , wherein the inner core is attached to the coil at a distal tip.

8. The thrombectomy apparatus of claim 1 , further comprising a polymeric material surrounding at least a distal portion of the coil to cover interstices of the coil.

9. The thrombectomy apparatus of claim 8 , wherein the inner core is composed of at least two twisted wires of stainless steel.

10. The thrombectomy apparatus of claim 8 , wherein the polymeric material is a coating.

11. The thrombectomy apparatus of claim 8 , wherein the polymeric material is a shrink wrap material.

12. The thrombectomy apparatus of claim 8 , wherein the outer wires do not extend beyond a terminal end of the inner core.

13. The thrombectomy apparatus of claim 8 , wherein the polymeric material is positioned proximal of the flexible tip.

14. The thrombectomy apparatus of claim 13 , wherein the polymeric material is positioned proximal of the metal tip.

15. The thrombectomy apparatus of claim 8 , wherein the polymeric material is positioned proximal of the metal tip.

16. The thrombectomy apparatus of claim 8 , wherein a proximal end of the metal tip is adjacent a distal end of the polymeric material.
