Abstract

A guidewire for medical procedures can be stored in a coiled configuration with a clamp. The clamp comprises a guidewire introducer funnel, which can be removably coupled to a hub of a catheter. The clamp comprises an adaptor to allow it to be removably coupled to a guidewire storage tube. The clamp comprises an interior channel configured to allow a guidewire to be advanced therethrough, and the interior channel can be coupled to the introducer and an adaptor that can be coupled to the back end of the clamp.

Claims

1. A clamp for facilitating guidewire storage, the clamp comprising:

a first portion, a second portion, and a pivotable portion therebetween;

an interior channel in the first or second portion configured to allow a guidewire to be advanced therethrough; and

a proximal adapter coupled to the interior channel and adapted to be removably coupled to a guidewire storage tube,

wherein the first and second portions are foldable or pivotable relative to one another about the pivotable portion to open or close the clamp, and

wherein the first and second portions comprise inward-facing surfaces configured to approximate or contact one another when the clamp is closed, the upper surfaces having one or more surface features to facilitate capture of the guidewire between the upper surfaces of the first and second portions.

2. The clamp of claim 1, wherein the one or more surface features comprise a high friction material or coating.

3. The clamp of claim 2, wherein the high friction material or coating is soft and compliant so as to minimize damage to a guidewire captured between the first and second portions.

4. The clamp of claim 1, wherein the proximal adapter is a male adapter sized and shaped to fit an interior of a guidewire storage tube.

5. The clamp of claim 1, wherein the proximal adapter is a female adapter sized and shaped to fit an exterior of a guidewire storage tube.

6. The clamp of claim 1, wherein the one or more surface features comprise teeth, ridges, or ribs to facilitate capture of one or more guidewire loops when the clamp is closed

7. The clamp of claim 1, wherein the first portion comprises a first set of teeth and the second portion comprises a second set of teeth, the first and second sets being complementary to one another.

8. The clamp of claim 7, wherein the first and second set of teeth fit within one another when the first and second portions are folded to close the clamp.

9. The clamp of claim 7, wherein tips of the first and second set of teeth abut one another when the first and second portions are folded to close the clamp.

10. The claim of claim 1, wherein the one or more teeth shaped to accommodate one or more guidewire loops comprises a plurality of cut-outs arranged in series, each cut-out being configured to accommodate a single guidewire loop.

11. The clamp of claim 1, wherein the one or more teeth shaped to accommodate the one or more guidewire loops comprises a cut-out having a plurality of semi-circular sections, the cut-out being configured to accommodate a plurality of guidewire loops.

12. The clamp of claim 1, further comprising a first end coupled to the first portion and a second end coupled to the second portion, the first and second ends being removably coupleable to one another.

13. The clamp of claim 12, wherein the first end comprises one or more teeth to capture the second end when the first and second portions are folded or pivoted relative to one another to close the clamp.

14. The clamp of claim 1, further comprising a guidewire introducer coupled to the interior channel, wherein the guidewire introducer has a guidewire lumen open to the interior channel, an open proximal end to receive the guidewire and direct the guidewire into the guidewire lumen, and a distal funnel tip to couple with a proximal hub of a catheter.

15. The clamp of claim 14, wherein the guidewire introducer further comprises a grasping mechanism to secure the guidewire received in the guidewire lumen.

16. The clamp of claim 14, wherein the guidewire introducer is removably coupled to one or more of the first or second portions.

17. A clamp for facilitating guidewire storage, the clamp comprising:

a first portion, a second portion, and a pivotable portion therebetween;

an interior channel in the first or second portion configured to allow a guidewire to be advanced therethrough; and

a proximal adapter coupled to the interior channel and adapted to be removably coupled to a guidewire storage tube,

wherein the first and second portions are foldable or pivotable relative to one another about the pivotable portion to open or close the clamp,

wherein the first and second portions comprise inward-facing surfaces configured to approximate or contact one another when the clamp is closed, the inward-facing surfaces having one or more surface features to facilitate capture of the guidewire between the inward-facing surfaces of the first and second portions,

wherein the one or more surface features comprise teeth, ridges, or ribs to facilitate capture of one or more guidewire loops when the clamp is closed,

wherein one or more of the first or second portions comprise one or more teeth,

wherein the one or more teeth are shaped to accommodate one or more guidewire loops,

wherein the one or more teeth shaped to accommodate the one or more guidewire loops comprises a cut-out having a plurality of semi-circular sections, the cut-out being configured to accommodate a plurality of guidewire loops, and

wherein the clamp further comprises a soft membrane over at least a portion of the cut-out.

18. The clamp of claim 17, wherein the first portion comprises a first set of teeth and the second portion comprises a second set of teeth, the first and second sets being complementary to one another.

19. The clamp of claim 18, wherein the first and second set of teeth fit within one another when the first and second portions are folded to close the clamp.

20. The clamp of claim 18, wherein tips of the first and second set of teeth abut one another when the first and second portions are folded to close the clamp.

21. The clamp of claim 17, wherein the proximal adapter is a male adapter sized and shaped to fit an interior of a guidewire storage tube.

22. The clamp of claim 17, wherein the proximal adapter is a female adaptor sized and shaped to fit an exterior of a guidewire storage tube.

23. The clamp of claim 17, wherein a portion of the one or more teeth shaped to accommodate one or more guidewire loops comprises a plurality of cut-outs arranged in series, each cut-out being configured to accommodate a single guidewire loop.

24. The clamp of claim 17, wherein the soft membrane comprises a high friction material or coating.

25. The clamp of claim 17, wherein the high friction material or coating is soft and compliant so as to minimize damage to a guidewire captured between the first and second portions.

26. The clamp of claim 17, further comprising a first end coupled to the first portion and a second end coupled to the second portion, the first and second ends being removably coupleable to one another.

27. The clamp of claim 26, wherein the first end comprises one or more teeth to capture the second end when the first and second portions are folded or pivoted relative to one another to close the clamp.

28. The clamp of claim 17, further comprising a guidewire introducer coupled to the interior channel, wherein the guidewire introducer has a guidewire lumen open to the interior channel, an open proximal end to receive the guidewire and direct the guidewire into the guidewire lumen, and a distal funnel tip to couple with a proximal hub of a catheter.
