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; and

a first thin wire gripping layer comprising a resilient material secured to the base assembly; and

a top assembly;

a magnet track disposed within the top assembly;

a second thin wire gripping layer secured to 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 first magnet comprises a neodymium magnet.

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

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

9. 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.

10. The disposable wire holder of claim 9, further comprising a handle track formed within the top layer and overlying the magnet track.

11. The disposable wire holder of claim 10, wherein the first magnet comprises a handle that extends outwardly through the handle track.

12. The disposable wire holder of claim 1, wherein the first thin wire gripping layer comprises a thin rubber layer.

13. The disposable wire holder of claim 1, wherein the second thin wire gripping layer comprises a thin rubber layer.
