Abstract

An arterial blockage percussive drill having a guiding sleeve, a drilling wire slidably coupled to the guiding sleeve and a percussive actuator coupled to the drilling wire to longitudinally oscillate the drilling wire into an arterial blockage.

Claims (19)

1. An arterial blockage percussive drill, comprising:

a vented guiding sleeve;

a drilling wire slidably coupled to said vented guiding sleeve;

a percussive actuator coupled to said drilling wire to longitudinally oscillate said drilling wire into an arterial blockage;

a perforated disk debris crusher coupled to said drilling wire to crush debris drilled out by said drilling wire and oscillated by said percussive actuator; and

a perforated disk debris filter coupled to said drilling wire to filter crushed debris and pass efflux to vents in said vented guiding sleeve.

2. The arterial blockage percussive drill of claim 1 , further comprising a guiding sleeve retractor.

3. The arterial blockage percussive drill of claim 1 , further comprising a guiding element coupled to said drilling wire to center said drilling wire in an artery.

4. The arterial blockage percussive drill of claim 1 , further comprising a portable housing coupled to said percussive actuator.

5. The arterial blockage percussive drill of claim 1 , further comprising a mountable housing coupled to said percussive actuator.

6. The arterial blockage percussive drill of claim 1 , wherein said percussive actuator is piezoelectric.

7. The arterial blockage percussive drill of claim 1 , further comprising a fluid access port coupled to said guiding sleeve to transport fluids to said drilling wire.

8. The arterial blockage percussive drill of claim 1 , further comprising a controller to modulate a stroke of said percussive actuator.

9. The arterial blockage percussive drill of claim 1 , wherein said percussive actuator is comprised of at least one of a stepped horn, a flextensional horn and a percussive rotary horn.

10. The arterial blockage percussive drill of claim 1 , wherein said guiding sleeve is angularly articulable.

11. The arterial blockage percussive drill of claim 1 , further comprising a rotary actuator coupled to said drilling wire to rotate said drilling wire.

12. The arterial blockage percussive drill of claim 11 , wherein said rotary actuator oscillates said drilling wire.

13. The arterial blockage percussive drill of claim 11 , wherein said rotary actuator rotates said drilling wire in one angular direction.

14. The arterial blockage percussive drill of claim 1 , wherein said arterial blockage is a total occlusion.
