Replacement valve and anchor
First Claim
1. A replacement heart valve system comprising:
- an anchor having a collapsed endovascular delivery configuration and a foreshortened deployed configuration;
a replacement valve support comprising a valve commissure support portion, the replacement valve support secured to the anchor in the anchor'"'"'s delivery and deployed configurations, wherein the commissure support portion has a length that is substantially the same in the anchor'"'"'s delivery and deployed configurations, wherein the anchor is adapted to foreshorten relative to the commissure support portion; and
a replacement valve supported by the commissure support portion, wherein the commissure support portion maintains substantially the same orientation while the anchor is in the deployed configuration.

Abstract
Apparatus for endovascularly replacing a patient'"'"'s heart valve, including: a replacement valve adapted to be delivered endovascularly to a vicinity of the heart valve; an expandable anchor adapted to be delivered endovascularly to the vicinity of the heart valve; and a lock mechanism configured to maintain a minimum amount of anchor expansion. The invention also includes a method for endovascularly replacing a patient'"'"'s heart valve. In some embodiments the method includes the steps of: endovascularly delivering a replacement valve and an expandable anchor to a vicinity of the heart valve; expanding the anchor to a deployed configuration; and locking the anchor in the deployed configuration.
