Abstract:
1. An adjustable annuloplasty device comprising: a body member comprising a shape memory material; an energy absorption enhancement material configured to absorb energy in response to a first activation energy, said energy absorption enhancement material in thermal communication with said shape memory material; wherein said body member has a first size of a body dimension in a first configuration and a second size of said body dimension in a second configuration; wherein said body member is configured to be implanted in said first configuration into a heart; wherein said body member is configured to transform from said first configuration to said second configuration in response to said first activation energy; wherein said second configuration is configured to reduce a dimension of a cardiac valve annulus in said heart; wherein said body member has a third size of said body dimension in a third configuration; wherein said third size is larger than said second size; and wherein said body member is configured to transform to said third configuration in response to a second activation energy to increase said dimension of said cardiac valve annulus.
