Claim 9:
10. A method for use at a native valve of a heart of a subject, the method comprising:
advancing, to the heart:
a distal portion of a delivery tool, the delivery tool including:
a shaft that extends to the distal portion of the delivery tool,
a capsule disposed at the distal portion of the delivery tool, and
a balloon, coupled to the shaft, and

an implant disposed within the capsule, and including a tubular frame and an array of shape-memory flanges arranged around an outside of the tubular frame, the tubular frame compressed around the balloon, and the flanges constrained within the capsule;

subsequently, exposing the flanges from the capsule such that the flanges automatically deflect radially outward away from the tubular frame, and such that the array defines an inter-flange distance;
subsequently, by partially inflating the balloon to a partially-inflated state:
(i) partially radially expanding the tubular frame, and (ii) partially increasing the inter-flange distance;

while the balloon remains in the partially-inflated state, pressing the flanges against a downstream surface of the native valve by moving the implant in an upstream direction; and
subsequently, by further inflating the balloon to a further-inflated state, further radially expanding the tubular frame.
