Abstract

A device for grasping a body part is preferably a catheter having a proximal end and distal end, the proximal end being juxtaposed a user while in use. A grasping section is attached to the catheter near or at the distal end. The grasping section has a first position wherein a body part may be received by the grasping section and a second position wherein the grasping section grasps the body part with sufficient force to enable the operator to move the body part to a desired location.

Claims

1. A catheter for grasping a body part comprising:

a proximal end that is juxtaposed an operator when being used;

a distal end comprising a grasping section, the grasping section having an open position and a closed position thereof, the grasping section not grasping the body part when in the open position and grasping the body part when in the closed position; and

wherein when in closed position, the grasping section is configured to grasp the body port with sufficient force to enable the operator to move the body part to a desired location.

2. The catheter of claim 1 wherein the grasping section is comprised of wire mesh.

3. The catheter of claim 2 wherein the wire mesh comprises nitinol.

4. The catheter of claim 2 wherein the wire mesh comprises stainless steel.

5. The catheter of claim 2 wherein the wire mesh has a generally circular cross section between 0.006 inches and 0.020 inches in diameter.

6. The catheter of claims 2 wherein the wire mesh has a generally circular cross section between 0.008 inches and 0.015 inches in diameter.

7. The catheter of claim 2 wherein the wire mesh is formed in a criss-cross pattern.

8. The catheter claim 2 wherein the wire mesh comprises struts that are substantially parallel to one another.

9. The catheter of claim 8 wherein each of the struts is between 0.006 inches and 0.020 inches in thickness.

10. The catheter of either of claims 8 wherein each of the struts has a width of between 0.010 inches and 0.030 inches.

11. The catheter of any of claim 1 wherein the grasping section has a proximal end and a distal end.

12. The catheter of claim 11 wherein the distal end of the grasping section is open when the grasping section is in its open position and the distal end is at least partially grasping the body part when the grasping section is in its closed position.

13. The catheter of either claims 11 wherein the distal end has an inward-facing edge for grasping a body part.

14. The catheter of any of claims 1 wherein the grasping portion comprises hooks for holding the body part when the grasping section is in its closed position.

15. The catheter of claim 13 wherein the inward-facing edge is discontinuous.

16. The catheter of any of claims 1 wherein there is an opening defined in the grasping section when the grasping section is in its open position, the opening for enabling the body part to be positioned therethrough and into a cavity in the grasping section.

17. The catheter of claim 16 wherein the opening is not at the distal end of the grasping section.

18. The catheter of claim 1 that has an inner tube and an outer tube, wherein the outer tube surrounds the interior tube and is movable relative the interior tube.

19. The catheter of claim 18 wherein the outer tube has a first position wherein the grasping section is in its open position, and a second position wherein the grasping section is in its closed position.

20. The catheter of either of claim 18 wherein the outer tube does not cover the grasping section when the outer tube is in its first position, and the outer tube at least partially covers the grasping section when the outer tube is in its second position.

21. The catheter of claim 20 wherein the grasping section is in its open position when the outer tube is in its first position and the catheter is in its closed position when the outer tube is in its second position.

22. The catheter of claim 1 that has a tip at its distal end.

23. The catheter of claim 22 wherein the tip is rounded.

24. The catheter of claim 22 wherein the tip is removable.

25. The catheter of claim 22 wherein the distal tip is attached to a stylus.

26. The catheter of claim 25 wherein the stylus is removable.

27. The catheter of claim 25 wherein the stylus is positioned in a lumen in the inner tube.

28. The catheter of claim 26 wherein the inner tube has a lumen and the stylus is positioned in the lumen prior to removal.

29. A catheter for grasping a body part, the catheter comprising:

a proximal end that is juxtaposed an operator when being used;

a distal end;

a grasping section juxtaposed the distal end, the grasping section having an open position and a closed position thereof, the grasping section not grasping the body part when in the open position and grasping the body part when in the closed position; and

wherein the grasping section grasps the body port with enough force to enable the operator to move the body part to a desired location.

30. The catheter of claim 29 that has an inner tube wherein the grasping section is at least partially formed on or attached to the inner tube.

31. The catheter of claim 29 wherein the inner tube has a lumen and there is an innermost tube retained at least partially inside the lumen.

32. The catheter of claim 31 wherein the grasping section is at least partially attached to or formed integrally with the innermost tube.

33. The catheter of claim 32 wherein the innermost tube has a first position and a second position, the grasping section being in its open position when the innermost tube is in its first position and being in its closed position when the innermost tube is in its second position.

34. The catheter of claim 29 wherein the grasping section has a first end attached to or integrally formed with an inner tube and a second end attached to or integrally formed with an innermost tube.

35. The catheter of claim 33 wherein the innermost tube extends outside of the lumen of the inner tube when in its first position and extends further outside of the lumen of the inner tube when in its second position.

36. The catheter of claim 29 that further includes an outer sheath that surrounds the inner sheath.

37. The catheter of claim 36 wherein the outer sheath has a first position wherein it covers the grasping portion and second position wherein it does not cover the grasping portion.

38. The catheter of claim 29 that further comprises a distal tip.

39. The catheter of claim 38 wherein the distal tip is rounded.

40. The catheter of claim 38 wherein the distal tip is solid.

41. The catheter of claim 38 wherein the distal tip is not removable.
