Claim 15:
16. A method of modifying a valve annulus, the method comprising:
delivering an anchor in a substantially non-coiled state to a valve annulus to be modified; and
deploying the anchor within tissue of the valve annulus such that the anchor self-transitions from the substantially non-coiled state to a pre-shaped coiled state,
wherein delivering the anchor includes constraining the anchor within a lumen of a needle disposed within a catheter, and deploying the anchor within the tissue includes moving at least a portion of the needle beyond the distal end of the catheter, and retracting at least a portion of the needle relative to the anchor to deploy at least a portion of the anchor from the lumen of the needle and thereby allow the anchor to assume the pre-shaped coiled state.
