First Claim
Patent Images
1. A system for replacing native valve function, the system comprising:
- a prosthetic heart valve having a collapsible and expandable stent forming cells, the stent having a plurality of sections including an annulus section, a transition section and an aortic section, and a valve assembly disposed in the stent; and
an occluder device comprising an expandable body having a first end and a second end, a fastener coupled to the first end of the body and to a selected strut of the stent at a first position on the annulus section of the stent, and an expandable disk coupled to the second end of the body and passing through a cell of the stent to couple the occluder device to the stent at a second position in a section other than the annulus section.

Abstract
An occluder for sealing gaps between a medical device and adjacent body tissue includes an expandable body configured to fill the gaps between the medical device and the body tissue. The occluder includes a fastener at one end of the body and adapted to couple to a first end of the medical device, and an expandable disk at the other end of the body and adapted to couple to the medical device at a position spaced from the first end.

15. A system for replacing native valve function, the system comprising:
-
a prosthetic heart valve having a collapsible and expandable stent forming cells, and a valve assembly disposed in the stent; and an occluder device comprising an expandable body having a first end and a second end, the first end and the second end being disposed on opposite ends of the body, a fastener extending in a first direction and coupled to the first end of the body, the fastener capable of latching onto an apex of a cell at a first position, and an expandable disk extending in a second direction, opposite the first direction, and coupled to the second end of the body, the expandable disk passing through a cell of the stent to couple the occluder device to the stent at a second position.

16. A method for occluding a gap between a prosthetic heart valve and adjacent body tissue, the method comprising:
-
providing; (1) a prosthetic heart valve having a collapsible and expandable stent forming cells, the stent having a plurality of sections including an annulus section, a transition section and an aortic section, and a valve assembly disposed in the stent; and (2) an occluder device comprising an expandable body having a first end and a second end, a fastener coupled to the first end of the body and to a selected strut of the stent at a first position on the annulus section of the stent, and an expandable disk coupled to the second end of the body and passing through a cell of the stent to couple the occluder device to the stent at a second position in a section other than the annulus section; delivering an occluder into an interior of the heart valve, the occluder including (i) an expandable body, (ii) a fastener coupled to one end of the body, and (iii) an expandable disk coupled to another end of the body; advancing the occluder through a cell of the prosthetic heart valve to an outside of the heart prosthetic valve; coupling the fastener to one end of the prosthetic heart valve; and coupling the expandable disk to the prosthetic heart valve at a position spaced from the one end. - View Dependent Claims (17, 18, 19, 20)
