Abstract

Described, in certain aspects of the invention, are apparatuses and methods for deploying artificial devices within the vascular system. One apparatus includes a delivery device having a lumen and a deployment member slidably received within the lumen. This apparatus further includes an artificial device having an anchoring element releasably engaged with the deployment member. Such an apparatus can be percutaneously delivered to a site within a vascular vessel, and thereafter manipulated so that the anchoring element attaches to the vessel wall. The delivery device and deployment member can then be withdrawn from the vessel, whereby the deployment member disengages from the anchoring element, leaving the artificial device implanted in the vessel.

Claims

1. An apparatus for deploying an artificial implant device within a vascular vessel, comprising:

a delivery device having a lumen;

at least one elongate deployment member slidably received within said lumen; and

an artificial implant device having at least one anchoring element for anchoring the artificial implant device to walls of the vessel, said at least one anchoring element releasably engaged with said at least one deployment member.

2. The apparatus of claim 1, having at least one elongate deployment member releasably engaged with a plurality of anchoring elements.

3. The apparatus of claim 1, having a plurality of elongate deployment members and a plurality of corresponding anchoring elements releasably engaged with said deployment members.

4. The apparatus of claim 1, wherein said at least one anchoring element is configured to disengage from said at least one elongate deployment member when sufficient force is applied to separate the deployment member from the anchoring element.

5. The apparatus of claim 1, wherein said artificial implant device comprises a flexible material.

6. The apparatus of claim 1, wherein at least a portion of said artificial implant device is receivable within said delivery device.

7. The apparatus of claim 1, wherein said at least one elongate deployment member is configured to receive a portion of said at least one anchoring element.

8. The apparatus of claim 1, wherein said at least one elongate deployment member is configured to receive at least a portion of said artificial implant device.

9. The apparatus of claim 1 having a plurality of elongate deployment members, wherein at least one of said plurality of elongate deployment members is configured to receive at least a portion of another elongate deployment member.

10. The apparatus of claim 1, wherein said at least one elongate deployment member has an end that is curved.

11. The apparatus of claim 1, further comprising a deflecting element for selectively deflecting said at least one elongate deployment member toward vessel walls.

12. The apparatus of claim 11, wherein said deflecting element is attached to said delivery device.

13. The apparatus of claim 11, wherein said deflecting element is at least partially received within said delivery device.

14. The apparatus of claim 11, wherein said delivery device provides said deflecting element.

30. The apparatus of claim 1, wherein the deployment member defines a lumen, and wherein the artificial implant device is received in and deployable from the lumen of the deployment member.

15. A method, comprising:

percutaneously delivering at least one anchoring element and at least one deployment member to a site within a vascular vessel, said at least one anchoring element releasably engaged with said at least one deployment member;

percutaneously attaching said at least one anchoring element to a wall of said vessel; and

withdrawing said at least one deployment member from said vessel, whereby said at least one anchoring element remains attached to said wall.

16. The method of claim 15, wherein said percutaneously delivering comprises deploying the at least one anchoring element from a lumen of a percutaneously advancable device.

17. The method of claim 16, wherein said percutaneously advancable device incorporates a deflecting element, said deflecting element adapted to selectively deflect said at least one deployment member toward a wall of said vessel.

18. The method of claim 16, wherein said deflecting element is slidably received within said percutaneously advancable device.

24. The method of claim 15, wherein a plurality of deployment members are releasably engaged with a plurality of corresponding anchoring elements.

19-23. -23. (canceled)

25-27. -27. (canceled)

28. An apparatus for attaching at least one anchoring element to a wall of a vascular vessel, comprising:

a delivery device having at least one deployment member passageway therethrough;

at least one deployment member slidably received within said at least one passageway; and

at least one anchoring element releasably engaged with said at least one deployment member.

29. The apparatus of claim 28, further comprising at least one valve leaflet attachable to said at least one anchoring element.

34. The apparatus of claim 28, also comprising an artificial implant device, wherein said anchoring element is attached to or incorporated into the artificial implant device, and wherein the artificial implant device is received in and deployable from a lumen of the deployment member.

35. The apparatus of claim 34, wherein said anchoring element is positioned at least partially external of the lumen of the deployment member.

37. The apparatus of claim 28, wherein the anchoring element comprises a barb.
