Patent ID: 8337390

Claim:
An intracardiac device for restoring functional elasticity of cardiac structures, in particular for the treatment of cardiomyopathies and valvulopathies, storing energy from the cardiac structures and ceding energy to the cardiac structures during the cardiac cycle; wherein the intracardiac device comprises an elongated shape and includes an elongated member formed from metal spring wire; the elongated member being at least partially wound in coils that extend circumferentially, along a given section, and is attachable to a cardiac structure; wherein said coils are selected in material, number, and dimension to permit elastic elongation of the intracardiac device higher than 10% of the rest length of the intracardiac device during use, and are adapted to be exposed to blood flow during use; and wherein the device further comprises at least one member directly attachable to the cardiac structure and attached to the elongated member, and the at least one member has an elongated shape and is arranged alongside and along the elongated member and is extendable up to a maximum length in order to limit extension of the elongated member within a given percentage of the rest length of the elongated member, and the attachable member includes a metal mesh tube intersecting with said coils; the metal mesh tube being extendable.
