Abstract

A hand held vibrating device for vibrating a guide wire used in angioplasty and atherectomy procedures. The vibrating device permits the guide wire to be more easily passed through a stenotic segment of a blood vessel. The vibrating device includes a case, an electric motor mounted within the case, and a clamp member coupled to the electric motor for releasably securing and vibrating the guide wire. In use, the guide wire is threaded through a blood vessel to the site of a stenosis. The guide wire can then be clamped to the vibrating device, which is selectively actuated and manipulated to vibrate and push the guide wire through the stenosis.

Claims

1. In a procedure wherein a guide wire or the like is placed through a blood vessel, a vibrating device for facilitating passage of the guide wire through the blood vessel, said vibrating device comprising:

holding means for releasably holding the guide wire; and

vibrating means coupled to the holding means for vibrating the guide wire such that the guide wire may be held and advanced through the blood vessel.

2. The vibrating device as recited in claim 1 and wherein the holding means includes:

clamp means for releasably securing the guide wire.

3. The vibrating device as recited in claim 2 and wherein:

the clamp means includes a resilient member for contacting the guide wire.

4. The vibrating device as recited in claim 3 and the vibrating means includes an electric motor.

5. The vibrating device as recited in claim 4 and wherein:

electric motor and clamp means are mounted to a case adapted to be hand held.

6. The vibrating device as recited in claim 5 and wherein:

the clamp means is movably mounted to the case in contact with an output shaft of the electric motor.

7. A vibrating device for vibrating a guide wire useful in an angioplasty or atherectomy procedure comprising:

a case sized and shaped to be hand held;

a vibrating motor mounted within the case and having an output member;

a clamp member slidably attached to the hand held case in contact with the output member of the vibrating motor for releasably holding the guide wire and for vibrating the guide wire; and

control means for selectively actuating the vibrating motor.

8. The vibrating device as recited in claim 7 and wherein:

the vibrating motor is an electric motor having an output shaft that moves the clamp member back and forth in a single plane.

9. The vibrating device as recited in claim 8 and wherein:

the control means includes a control circuit formed on a circuit board mounted within the case.

10. The vibrating device as recited in claim 9 and wherein:

the vibrating motor is battery operated.

11. The vibrating device as recited in claim 10 and wherein:

the clamp member includes a base portion and a clip portion each having a resilient member for contacting the guide wire.

12. The vibrating device as recited in claim 11 and wherein:

the control means includes an on-off switch for actuating the vibrating motor.

13. In an angioplasty or atherectomy procedure wherein a guide wire is introduced into a blood vessel and guided through the blood vessel to a stenosis located in the blood vessel, a vibrating device for vibrating the guide wire such that it may be more easily guided through the stenosis, said vibrating device comprising:

a case sized and shaped to be hand held;

an electric vibrating motor mounted within the case and including an output shaft;

a control circuit for operating the vibrating motor mounted within the case and coupled to a power source and to a switch for operating the motor; and

a clamp member for releasably holding the guide wire with the clamp member slidably mounted to the case in contact with the output shaft of the vibrating motor for movement by the vibrating motor.

14. The vibrating device as recited in claim 13 and wherein:

the clamp member includes a counterbored slot that mates with a stepped output shaft of the vibrating motor.

15. The vibrating device as recited in claim 14 and wherein:

the clamp member is slidably mounted on the case for movement in a lateral plane.

16. The vibrating device as recited in claim 15 and wherein:

the clamp member includes a mounting slot that mates with a mounting track formed on the case.

17. The vibrating device as recited in claim 16 and the clamp member includes a resilient member for contacting the guide wire.

18. The vibrating device as recited in claim 17 and the switch for operating the motor includes an exposed push button for manual actuation.

19. The vibrating device as recited in claim 18 and wherein:

the power source for the vibrating motor is a battery mounted to a printed circuit board in the case.

20. The vibrating device as recited in claim 19 and wherein:

the control circuit is configured for recharging the battery with an external power source.

21. The vibrating device as recited in claim 19 and wherein:

the case is formed with a top portion and a bottom portion including internal ribs to form separate compartments for the clamp member, the printed circuit board, and the motor.
