A system for replacing native valve function, the system comprising:
- a prosthetic heart valve having a collapsible and expandable stent, the stent having a plurality of sections, 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 portion of the stent at a first position adjacent a first section of the stent, and a disk coupled to the second end of the body and to a portion of the stent at a second position in a section other than the first section.
A method for occluding a gap between a prosthetic heart valve and adjacent body tissue, the method comprising:
- delivering an occluder to 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;
- 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.
