Abstract
An adjustable annuloplasty ring assembly (10) comprises a support ring (30), an adjustable ring (32) nested at least partly within the support ring, and at least one deployable pressing element (34) for deforming the adjustable ring using the support ring (30) as support. Plural pressing elements (34) may be used at different positions around rings. Each pressing element (34) may have a variable extents of deployment, to vary the extent of deformation of the adjustable ring at the position of the pressing element. Each pressing element may comprise a deflectable blade (40), and the state of the blade may be retained by a ratchet (50). The pressing elements may be operated in a predetermined controlled sequence.
