Adjustable annuloplasty ring and system

An adjustable annulopasty ring assembly, the assembly comprising:

• a support ring,
• an adjustable ring nested at least partly within the support ring, and
• at least one pressing element deployable to deform the adjustable ring by using the support ring as a support, for adjusting the shape of the adjustable ring,
• wherein at least a portion of the at least one deployable pressing element is configured to remain, in use during deployment of the pressing element, generally at a predetermined position along a periphery of at least one of the rings.

An adjustable annuloplasty ring assembly, the assembly comprising:

• a support ring,
• an adjustable ring nested at least partly within the support ring, and
• at least one pressing element deployable to deform the adjustable ring by using the support ring as a support, for adjusting the shape of the adjustable ring,
• wherein the at least one pressing element is controllable to have a variable extent of deployment at the position of the pressing element, to define a variable deformation of the adjustable ring with respect to the support ring,

An adjustable annuloplasty ring assembly, the assembly comprising:

• a support ring,
• an adjustable ring nested at least partly within the support ring, and
• at least one pressing element deployable to deform the adjustable ring by using the support ring as a support, for adjusting the shape of the adjustable ring,
• wherein the at least one deployable pressing element comprises a deflectable blade configured to bow in response to application of mechanical force to at least a portion of the deflectable blade.
