1. A method of replacing a heart valve, comprising:
- endovascularly delivering a replacement valve and an expandable anchor within a delivery device to a vicinity of a heart valve, wherein the expandable anchor has a delivery configuration within the delivery device, a partially-deployed self-expanded configuration, and a fully expanded configuration;
expanding the anchor from the delivery device in the vicinity of the heart valve; and
repositioning the anchor in the vicinity of the heart valve while the expandable anchor is in the partially-deployed self-expanded configuration, wherein the repositioning step occurs without retrieving the anchor into the delivery device.

Abstract
A method for percutaneously replacing a heart valve of a patient. In some embodiments the method includes the steps of percutaneously delivering a replacement valve and an expandable anchor to a vicinity of the heart valve in an unexpanded configuration; expanding the anchor to a deployed configuration in which the anchor contacts tissue at a first anchor site; repositioning the anchor to a second anchor site; and deploying the anchor at the second anchor site.

8. A method of recapturing a replacement heart valve apparatus, comprising:
-
endovascularly delivering a replacement valve and an expandable anchor within a delivery device to a vicinity of a heart valve, wherein the expandable anchor has a delivery configuration, a partially deployed, self-expanded configuration, and a fully expanded configuration; allowing the anchor to self-expand from the delivery configuration in the delivery device to the partially deployed, self-expanded configuration in the vicinity of the heart valve; and retrieving the expandable anchor within the delivery device, wherein retrieving the expandable anchor comprises collapsing the expandable anchor from the partially deployed, self-expanded configuration to the delivery configuration. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)
