Artificial device deployment apparatus
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 The delivery device and deployment member can then be withdrawn from the vessel, whereby the deployment member disengages from the anchoring element, leaving the artificial device implanted in the vessel.
1. An apparatus for modifying blood flow within a vascular vessel, comprising:
a delivery device having a lumen;
at least one elongate deployment member slidably received within said lumen;
an artificial implant device comprising a valve and having at least one anchoring element for anchoring the artificial implant device to walls of the vessel, said at least one anchoring element releasably and directly engaged with said at least one elongate deployment member;
a deflecting element slidably received in the delivery device independent of the at least one elongate deployment member, the deflecting element having a distal region presenting an angled portion positionable distally of a distal end of the delivery device; and
wherein a lateral surface of the at least one elongate deployment member is movable against and along a surface of the angled portion of the deflecting element so as to deflect the at least one elongate deployment member and the at least one anchoring element toward a wall of the vascular vessel.
2. The apparatus of claim 1 , wherein the at least one anchoring element comprises a barb.
3. The apparatus of claim 1 , wherein said at least one elongate deployment member includes a plurality of elongate deployment members and wherein said at least one anchoring element includes a plurality of anchoring elements each releasably engaged with a corresponding one of said elongate 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 , wherein said at least one elongate deployment member has an end that is curved.
10. An apparatus for modifying blood flow within 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;
at least one anchoring element releasably and directly engaged with said at least one deployment member;
at least one valve leaflet attachable to said at least one anchoring element a deflecting element slidably received in the delivery device, the deflecting element having a distal region slidably positionable distally of a distal end of said delivery device and distally of said at least one anchoring element releasably engaged with said at least one deployment member; and
wherein said distal region is configured to deflect said at least one deployment member toward a wall of the vascular vessel upon movement of said at least one deployment member against said distal region.
11. The apparatus of claim 10 , wherein said distal region presents an angled portion, and wherein a lateral surface of the at least one deployment member is movable against and along a surface of the angled portion so as to deflect the at least one elongate deployment member toward the wall of the vascular vessel.
12. The apparatus of claim 10 , wherein the at least one anchoring element comprises a barb.
13. An apparatus for deploying an artificial implant device within a vascular vessel, comprising:
a delivery device having a lumen;
at least one elongate member slidably received within said lumen;
an artificial implant device comprising a valve and having at least one barb for anchoring the artificial implant device to a wall of the vessel, the at least one barb releasably and directly engaged with the at least one elongate member; and
an elongate element slidably received in the delivery device, the elongate element having a distal region presenting an angled portion positionable distally of a distal end of the delivery device; and
wherein a lateral surface of the at least one elongate member is movable against and along a surface of the angled portion when the angled portion is positioned distally of the distal end of the delivery device, so as to deflect the at least one elongate member and thereby the at least one barb toward a wall of the vascular vessel.
14. The apparatus of claim 13 , wherein the at least one elongate member includes a plurality of elongate members and wherein the at least one barb includes a plurality of barbs each releasably engaged with a corresponding one of the elongate members.
15. The apparatus of claim 13 , wherein the at least one barb is configured to disengage from the at least one elongate member when sufficient force is applied to separate the elongate member from the barb.
16. The apparatus of claim 13 , wherein the artificial implant device comprises a flexible material.
17. The apparatus of claim 13 , wherein at least a portion of said artificial implant device is receivable within said delivery device.
18. The apparatus of claim 13 , wherein said at least one elongate member is configured to receive a portion of said at least one barb.
19. The apparatus of claim 13 , wherein said at least one elongate member is configured to receive at least a portion of said artificial implant device.
