Abstract

A percutaneous medical device that may include a stopper having a first end, a second end and a lumen therebetween, the stopper having first state where the lumen has a first cross-sectional area and a second state where the lumen has a second cross-sectional area less than the first cross-sectional area, the stopper having a slit between the first end and the second end when in the first state, the slit defining a gap, the stopper when in the second state having no bias to move to the first state at body temperature, the stopper having a distance of less than 3 cm between the first end and the second end and apparatus and methods of use pertaining thereto.

Claims

1. A kit for the conversion of a guidewire into a distal protection guidewire, comprising:

a distal protection member having a lumen therethrough for receiving any guidewire having a outer diameter of a certain size or less; and

a stopper fixable to a guidewire, the stopper having a lumen extending from a proximal end of the stopper to a distal end of the stopper.

2. The kit of claim 1, wherein the lumen of the stopper is substantially empty.

3. The kit of claim 1, wherein the stopper has a first state where the lumen has a first cross-sectional area and a second state where the lumen has a second cross-sectional area less than the first cross-sectional area.

4. The kit of claim 3, where the stopper has an arcuate shape in the first state and a closed loop shape in the second state.

5. The kit of claim 1, further comprising a second stopper fixable to a guidewire, the second stop having the same size as the first stopper.

6. The kit of claim 1, further comprising a second stopper fixable to a guidewire, the second stopper being fixable to guidewire of larger cross-sectional area than the first stopper.

7. The kit of claim 1, wherein the stopper is plastically deformable from the first state to the second state.

8. The kit of claim 1, further comprising a tool for fixing the stopper to a guidewire.

9. The kit of claim 8, wherein the tool has a pair of jaws having opposing surfaces whose profiles correspond to the profile of the outer surface of the stopper.

10. The kit of claim 8, wherein the tool has a stopper for preventing the jaws from closing beyond a certain point.

11. The kit of claim 10, wherein the stopper is a pair of opposing surfaces on the jaws.

12. The kit of claim 1, wherein the stopper is attached to the distal protection member

13. A method of converting a guidewire into a distal protection guidewire, comprising the steps of:

providing a distal protection member having a distal end a proximal end and a lumen therebetween, the distal protection member having a first compact state and a second expanded state for trapping emboli; and

providing a first stopper defining an inner cross-sectional area, the stopper having a first state where the inner cross-sectional area has a first magnitude and a second state where the inner cross-sectional area has a second magnitude less that the first magnitude, the stopper having an outer profile in the second state such that the distal protection member cannot pass over it.

14. The method of claim 13, wherein the stopper is compressible from the first state to the second state.

15. The method of claim 13, further comprising the step of providing a tool for fixing the stopper to a guidewire.

16. The method of claim 13, further comprising the step of providing a second stopper, the second stopper having a first state where the inner cross-sectional area has a first magnitude and a second state where the inner cross-sectional area has a second magnitude less that the first magnitude, the second stopper having an outer profile in the second state such that the distal protection member cannot pass over it.

17. The method of claim 13, wherein the step of providing the first stopper includes the step of providing the first stopper in the first state to a medical facility that performs therapeutic treatments of patients.

18. A method of converting a guidewire into a distal protection guidewire, comprising the steps of:

providing a first stopper in a first state to a medical facility that performs therapeutic treatments of patients, the stopper defining a lumen having an inner cross-sectional area, the first state being where the inner cross-sectional area has a first magnitude and the stopper having a second state where the inner cross-sectional area has a second magnitude less that the first magnitude, the stopper having an outer profile in the second state such that the distal protection member cannot pass over it.

19. A percutaneous medical device, comprising

a stopper having a first end, a second end and a lumen therebetween,

the stopper having first state where the lumen has a first cross-sectional area and a second state where the lumen has a second cross-sectional area less than the first cross-sectional area,

the stopper having a slit between the first end and the second end when in the first state, the slit defining a gap,

the stopper when in the second state having no bias to move to the first state at body temperature,

the stopper having a distance of less than 3 cm between the first end and the second end;

and

no member having a length of greater than 10 cm.

20. The device of claim 19, wherein the stopper has an inner surface having a texture.

21. The device of claim 20, wherein the texture is a plurality of ribs disposed on the inner surface.

22. The device of claim 19, wherein the stopper has a cylindrical profile in the second state.

23. The device of claim 19, wherein the stopper has a spherical profile in the second state.

24. The device of claim 19, wherein the stopper Is plastically deformable.

25. The device of claim 24, wherein the stopper includes a material selected from the group of tin, silver and gold.

26. The device of claim 25, wherein the stopper comprises a shape memory material that biases the stopper to the second state at body temperature.

27. The device of claim 26, wherein the stopper is biased to the first state at a temperature higher than body temperature.

28. The device of claim 19, wherein the stopper Is made of a material that is elastically deformable between the first state and the second state.

29. The device of claim 19, further comprising a sterile package surrounding the stopper.

30. The device of claim 29, wherein the lumen is empty.

31. The device of claim 29, further comprising a spacer removably disposed in the lumen.

32. The device of claim 19, wherein the stopper is affixable to a guidewire by moving the stopper to the second state when on the guidewire.
