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.
1. A method for endovascularly replacing a patient's heart valve, the method comprising: endovascularly delivering a replacement valve and an expandable anchor to a vicinity of the heart valve;expanding the anchor to a deployed configuration; andlocking the anchor in the deployed configuration to pr
1. A method for endovascularly replacing a patient's heart valve, the method comprising: endovascularly delivering a replacement valve and an expandable anchor to a vicinity of the heart valve;expanding the anchor to a deployed configuration; andlocking the anchor in the deployed configuration to prevent contraction of the anchor from the deployed configuration,wherein the locking step comprises connecting a first interlocking element associated with a first anchor region with a second interlocking element associated with a second anchor region,wherein the expanding step comprises axially moving the first interlocking element toward the second interlocking element, andwherein expanding the anchor to the deployed configuration comprises applying an actuation force on the anchor with a deployment tool. 2. The method of claim 1 wherein locking the anchor in the deployed configuration comprises axially locking the anchor in a foreshortened configuration. 3. The method of claim 1 wherein applying the actuation force on the anchor with the deployment tool comprises applying the actuation force on the first interlocking element or the second interlocking element. 4. The method of claim 3 wherein applying the actuation force on the first interlocking element or the second interlocking element comprises applying a proximally directed actuation force on the first interlocking element or the second interlocking element. 5. A method for endovascularly replacing a patient's heart valve, the method comprising: endovascularly delivering a replacement valve and an expandable anchor to a vicinity of the heart valve;expanding the anchor to a deployed configuration; andlocking the anchor in the deployed configuration to prevent contraction of the anchor from the deployed configuration,wherein the expanding step comprises applying an actuation force on the anchor through an actuator, andwherein the applying step comprises applying a proximally directed force on the anchor. 6. The method of claim 5 further comprising releasing the actuator from the anchor. 7. The method of claim 5 wherein the expanding step comprise moving a first anchor region toward a second anchor region. 8. A method for endovascularly replacing a patient's heart valve, the method comprising: endovascularly delivering a replacement valve and an expandable anchor to a vicinity of the heart valve;expanding the anchor to a deployed configuration; andlocking the anchor in the deployed configuration to prevent contraction of the anchor from the deployed configuration,wherein the expanding step comprises applying an actuation force on the anchor through an actuator,wherein the applying step comprises applying a distally directed force on the anchor. 9. The method of claim 8 further comprising releasing the actuator from the anchor. 10. The method of claim 8 wherein the expanding step comprise moving a first anchor region toward a second anchor region.
