Abstract

A device can easily and releasably secure a medical wire such as a guidewire or a filter wire. In some instances, such a device can include a wire holding device that may be considered to be disposable. A wire holding device may include a base fixture, a clamp fixture, holding apparatus to hold the clamp fixture to the base fixture, releasing apparatus to release the clamp fixture from the base fixture, and selecting apparatus to select between the holding apparatus and the releasing apparatus.

Claims

1. A disposable wire holder configured to releasably secure a medical wire, the disposable wire holder comprising:

a base assembly;

a first magnet disposed within the base assembly, the first magnet having a first polarity;

a second magnet disposed within the base assembly, the second magnet having a second polarity;

a top assembly;

a magnet track disposed within the top assembly; and

a third magnet disposed within the magnet track, the third magnet translatable between an open position in which the third magnet overlies the first magnet and a closed position in which the third magnet overlies the second magnet.

2. The disposable wire holder of claim 1, wherein the top assembly releases from the base assembly when the third magnet is in the open position.

3. The disposable wire holder of claim 1, wherein the top assembly is secured to the base assembly when the third magnet is in the closed position.

4. The disposable wire holder of claim 1, wherein the third magnet has a polarity equal to the first polarity and opposite to the second polarity.

5. The disposable wire holder of claim 1, further comprising at least one hinge securing the top assembly to the base assembly.

6. The disposable wire holder of claim 1, wherein the top assembly comprises a lower surface comprising a gripping surface attached thereto.

7. The disposable wire holder of claim 1, wherein the bottom assembly comprises an upper surface comprising a gripping surface attached thereto.

8. The disposable wire holder of claim 1, wherein the first magnet comprises a neodymium magnet.

9. The disposable wire holder of claim 1, wherein the second magnet comprises a neodymium magnet.

10. The disposable wire holder of claim 1, wherein the third magnet comprises a neodymium magnet.

11. The disposable wire holder of claim 1, wherein the top assembly comprises a top layer, a middle layer and a bottom layer, where the magnet track is formed within the middle layer.

12. The disposable wire holder of claim 11, further comprising a handle track formed within the top layer and overlying the magnet track.

13. The disposable wire holder of claim 12, wherein the first magnet comprises a handle that extends outwardly through the handle track.

14. A medical wire clamp, comprising:

a base fixture;

a clamp fixture;

holding means to hold the clamp fixture against the base fixture;

releasing means to release the clamp fixture from the base fixture; and

selecting means to select between the holding means and the releasing means.

15. The medical wire clamp of claim 14, further comprising wire gripping means disposed between the base fixture and the clamp fixture.

16. The medical wire clamp of claim 14, wherein the medical wire clamp is configured to secure a medical wire when the holding means holds the clamp fixture against the base fixture.

17. The medical wire clamp of claim 14, wherein the medical wire clamp is configured to release a medical wire when the releasing means releases the clamp fixture from the base fixture.

18. A method of using a medical wire clamp, the medical wire clamp comprising a base fixture, a clamp fixture, holding means to hold the clamp fixture against the base fixture and releasing means to release the clamp fixture from the base fixture, the method comprising steps of:

advancing a medical wire to a treatment site, the medical wire including a proximal portion and a distal portion;

positioning the distal portion of the medical wire within the medical wire clamp; and

activating the holding means to hold the clamp fixture to the base fixture, thereby securing the medical wire.

19. The method of claim 18, further comprising a step of advancing a catheter over the medical wire subsequent to activating the holding means.

20. The method of claim 19, further comprising a step of activating the release means to release the clamp fixture from the base fixture subsequent to withdrawing the catheter.
