Abstract

This invention relates to medical devices for manipulating medical implants such as, for example, stents, distal protection filters, and septal occluders in a patient'"'"'s body, and the methods of use thereof. Generally, a medical device of the invention includes a sleeve and an expandable component joined to the sleeve which transitions between a collapsed configuration and a deployed configuration for capturing a medical implant in a patient'"'"'s body.

Claims

1. A medical device for manipulating a medical implant in a patient'"'"'s body comprising:

a sleeve comprising a lumen, a distal end and a proximal end;

an expandable component, wherein at least a portion of the expandable component is joined to the sleeve, the expandable component transitioning between a collapsed configuration when the expandable component is enclosed by the sleeve, and a deployed configuration, wherein a portion of the expandable component is extended beyond the distal end of the sleeve.

2. The medical device of claim 1, wherein manipulating comprises capturing the medical implant.

3. The medical device of claim 2, wherein capturing comprises delivering the medical implant in the patient'"'"'s body.

4. The medical device of claim 2, wherein capturing comprises retrieving a medical device from the patient'"'"'s body.

5. The medical device of claim 1, wherein the expandable component is reciprocatably moveable relative to the sleeve.

6. The medical device of claim 1, wherein the sleeve is reciprocatably moveable relative to the expandable component.

7. The medical device of claim 1, wherein at least a portion of the expandable component is joined to the distal end of the sleeve.

8. The medical device of claim 1, wherein the expandable component comprises a conical shape in the deployed configuration.

9. The medical device of claim 1, further comprising an elongate member.

10. The medical device of claim 9, wherein the at least a portion of the expandable component is secured to the elongate member.

11. The medical device of claim 9, wherein the elongate member is slideably moveable within the lumen of the sleeve.

12. The medical device of claim 1, wherein the expandable component is sized and shaped to manipulate a septal occluder in a patient'"'"'s body.

13. The medical device of claim 1, wherein the expandable component is sized and shaped to manipulate a distal protection filter in a patient'"'"'s body.

14. The medical device of claim 1, wherein the expandable component comprises a mesh.

15. The medical device of claim 14, wherein the mesh is cylindrical.

16. The medical device of claim 1, wherein the expandable component comprises braided material.

17. The medical device of claim 1, wherein the expandable component comprises an elastomeric tube.

18. A method for manipulating a medical implant in a patient'"'"'s body comprising:

providing a medical device comprising a sleeve comprising a lumen, a distal end and a proximal end and an expandable component, wherein at least a portion of the expandable component is joined to the sleeve, the expandable component transitioning between a collapsed configuration when the expandable component is enclosed by the sleeve, and a deployed configuration wherein a portion of the expandable component is extended beyond the distal end of the sleeve.

19. The method of claim 18, wherein manipulating comprises capturing the medical implant.

20. The method of claim 19, wherein capturing comprises recovering the medical implant from the patient'"'"'s body.

21. The method of claim 19, wherein capturing comprises delivering the medical implant inside the patient'"'"'s body.

22. The method of claim 18, wherein the medical implant is selected from the group consisting of a septal occluder, a stent and a distal protection filter.

23. The method of claim 18, further comprising an elongate member slideably moveable within the lumen of the sleeve.

24. A medical device for capturing a medical implant in a patient'"'"'s body comprising:

a sleeve means;

an expandable means, wherein at least a portion of the expandable means is joined to the sleeve means, the expandable means transitioning between a collapsed configuration when the expandable means is enclosed by the sleeve means, and a deployed configuration, wherein a portion of the expandable means is extended beyond the sleeve means; and

means for deploying the expandable means beyond the sleeve means.
