Abstract

Devices and methods for unwrapping (or otherwise overcoming the entanglement of), or preventing the wrapping of, guidewires and similar elongated medical devices deployed (or about to be deployed) in vessels of a patient. Embodiments have sufficient flexibility to be deployed by distally threading at least one lumen over a guidewire, and sufficient torqueability to enable axial rotation of the combination to unwrap the entangled devices or prevent further entanglement as additional guidewires are advanced through other lumens.

Claims

AMENDED CLAIMS received by the International Bureau on 18 June 2008 (18.06.2008) We claim:
1. An apparatus for use with guidewires prone to entanglement during advancement into a vessel, the apparatus comprising a main body, having proximal and distal ends, combined with at least two lumens supported by the main body; in which the apparatus has sufficient flexibility to be advanced through the vessel before at least one of the guidewires is advanced into the vessel through one of the lumens of the apparatus, to thereby prevent entanglement of the guidewires; in which the apparatus is further characterized by sufficient torqueability to enable axial rotation of the apparatus to prevent entanglement of the guidewires.
2. An apparatus for use with guidewires prone to entanglement during advancement into a vessel, the apparatus comprising a main body, having proximal and distal ends, combined with at least two lumens supported by the main body; in which the apparatus has sufficient flexibility to be advanced through the vessel after the guidewires are advanced into the vessel before the apparatus; in which the apparatus disentangles the guidewires by being advanced through the vessel over the guidewires, each guidewire passing though one of the lumens; the apparatus further characterized by sufficient torqueability to enable axial rotation of the apparatus to disentangle the guidewires.
3. [Cancelled.]
4. [Cancelled.]
5. The apparatus of claim 1 or 2, further comprising at least one lumen extension extending distally from the distal end of the main body; and further in which at least one lumen extends distally from the distal end of the main body throughout its respective lumen extension to a distal opening of such lumen.
6. The apparatus of claim 1 or 2, in which at least one lumen has a proximal opening on the proximal end of the main body.
7. The apparatus of claim 1 or 2, in which at least one lumen has a proximal opening intermediate between the proximal and distal ends of the main body.
8. The apparatus of claim 1 or 2, in which the main body comprises a flexible material, and each lumen comprises a loop at the distal end of the main body.
9. The apparatus of claim 1 or 2, in which each lumen is a portion of a single passage having two distinct portions, such that a single guidewire may fit into a portion but not migrate to another portion.
10. The apparatus of claim 1 or 2, in which each lumen is a portion of a single passage and the two lumens are partially joined together.
11. The apparatus of claim 1 or 2, in which each lumen is a portion of a single passage and the passage comprises a neck-like region between the two lumens.
12. A method for unwrapping guidewires advanced into a vessel, the guidewires each having respective proximal ends and distal ends, comprising:
a) providing an apparatus comprising a main body combined with at least two lumens;
b) threading each lumen onto respective proximal ends of guidewires;
c) distally advancing the apparatus through the vessel over the guidewires; and
d) twisting the main body as necessary to unwrap the guidewires.
13. The method of claim 12, further comprising:
e) removing the apparatus from the unwrapped guidewires.
14. The method of claim 12, in which the vessel is a portion of vasculature.
15. The method of claim 12, in which the vessel is a portion of one of lymphatic, urinary, reproductive, respiratory, or digestive systems.
16. The method of claim 12, in which at least one lumen is defined within the main body.
17. The method of claim 12, in which at least one lumen is defined outside the main body.
18. The method of claim 12, in which the main body defines exactly two lumens.
19. A method for preventing the entanglement of guidewires within a vessel, each guidewire having respective proximal ends and distal ends, the method comprising:
a) providing an apparatus comprising a main body having a distal end, combined with at least two lumens,
b) distally advancing the apparatus into the vessel;
c) advancing at least one guidewire into a respective lumen; and
d) removing the apparatus from the vessel over the proximal ends of the guidewires.
20. The method of claim 19, in which the vessel is a portion of vasculature.
21. The method of claim 19, in which the vessel is a portion of one of lymphatic, urinary, reproductive, respiratory, or digestive systems.
22. The method of claim 19, in which at least one lumen is defined within the main body.
23. The method of claim 19, in which at least one lumen is defined outside the main body.
24. The method of claim 19, in which the main body defines exactly two lumens.
25. The method of claim 19, in which a first guidewire is advanced into the vessel prior to advancing the apparatus into the vessel, after which the apparatus is advanced into the vessel over the first guidewire, followed by advancing a second guidewire through the respective lumen.
26. The method of claim 19, in which the second guidewire is initially outside the respective lumen.
27. The method of claim 19, in which the second guidewire is initially preloaded within the respective lumen.
21
28. An apparatus for unwrapping guidewires advanced into a vessel or preventing the entanglement of guidewires to be advanced into a vessel, comprising a main body, having proximal and distal ends, combined with two lumens defined within the main body; and at least one lumen extension extending distally from a distal end of the main body, in which at least one lumen extends distally from the distal end of the main body throughout its respective lumen extension to a distal opening of such lumen; the apparatus having sufficient flexibility to be advanced through the vessel over at least one of the guidewires, and sufficient torqueability to enable axial rotation of the apparatus to unwrap or prevent entanglement of the guidewires.
29. The apparatus of claim 28, further comprising a handle connected to the proximal end of the main body.
30. The apparatus of claim 28, in which at least one lumen has a proximal opening on the proximal end of the main body.
31. The apparatus of claim 28, in which at least one lumen has a proximal opening intermediate between the proximal and distal ends of the main body.
32. The apparatus of claim 28, in which each lumen is a portion of a single passage having two distinct portions, such that a single guidewire may fit into a portion but not migrate to another portion.
33. The apparatus of claim 28, in which each lumen is a portion of a single passage and the two lumens are partially joined together.
34. The apparatus of claim 28, in which each lumen is a portion of a single passage and the passage comprises a neck-like region between the two lumens.
