Method of using a retrievable heart valve anchor with a sheath
First Claim
1. A method for endovascularly positioning a replacement heart valve of a patient, the method comprising:
- endovascularly delivering to a vicinity of the patient'"'"'s heart valve a replacement heart valve comprising replacement leaflets coupled to an expandable anchor, the expandable anchor in an unexpanded configuration within a sheath, wherein the expandable anchor comprises a skirt region opposite a lip region;
releasing the anchor from the sheath;
deploying the anchor at a first position by applying at least one of a distally directed force to the lip region of the anchor with a plurality of tubes and simultaneously a proximally directed force to the skirt region of the anchor with a plurality of wires after the anchor is completely out of the delivery sheath, wherein the applied forces are non-hydraulic and non-pneumatic actuation forces;
retrieving the anchor into the sheath after the deploying at a first position step; and
repositioning the valve by releasing the anchor from the sheath and deploying the anchor at a second position.

Abstract
A method for endovascularly replacing a heart valve of a patient. In some embodiments the method includes the steps of: endovascularly delivering a replacement valve and an expandable anchor in an unexpanded configuration within a catheter to a vicinity of the heart valve; deploying the anchor from the catheter; expanding the anchor to contact tissue at an anchor site; and retrieving the anchor into the catheter. The invention also includes an apparatus for endovascularly replacing a heart valve, including: a catheter; a replacement valve configured to be disposed within the catheter for delivery to a vicinity of the heart valve; and an expandable anchor configured to be disposed within the catheter for delivery to a vicinity of the heart valve, to be deployed from the catheter, to be expanded to contact tissue at an anchor site and to be retrieved back into the catheter after having been expanded.
