Abstract

A method is provided, including positioning an annuloplasty structure along an annulus of an atrioventricular valve of a subject, the annuloplasty structure including a sleeve having a lumen. The annuloplasty structure is fastened to the annulus. Thereafter, an elongate member is advanced into the lumen, such that an elongate contraction-restricting element of the elongate member occupies a longitudinal contraction-restricted portion of the sleeve. Thereafter, a contractible portion of the sleeve is contracted, while the contraction-restricting element restricts contraction of the contraction-restricted portion of the sleeve.
