Abstract:
1. A method comprising: attaching an implantable device in a blood vessel; and after attaching, constricting a valve annulus near the blood vessel by shortening a length of the implantable device in the blood vessel, wherein the implantable device comprises a tubular device having at least two shrink segments, each shrink segment disposed between a different pair of at least three attachable portions attached to the blood vessel, wherein shortening the length comprises expanding the at least two shrink segments, and wherein each of the two shrink segment that is expanded is individually expanded by a different corresponding segment of a balloon by expanding each different corresponding segment of the balloon using a separate lumen, wherein expanding comprises gradually shortening the length of the implantable device by first expanding a shrink segment adjacent to an already attached attachable portion at an end of the implantable device, and then expanding a second shrink segment later.
