心内構造物の機能的な弾性を回復させるための心臓デバイス、心臓デバイスを保持するための器具、および心臓デバイスの心臓への埋め込み方法

摘要

An intracardiac device for restoring the functional elasticity of the cardiac structures, in particular for the treatment of cardiomyopathies and or valvulopathies, by storing energy from the cardiac structures and ceding energy to the cardiac structures during the cardiac cycle, has an elongated shape, is at least partially wound in coils and is attachable to a cardiac structure; the coils are selected in material, number and dimension so as to allow an elastic elongation of the intracardiac device higher than 10% of the rest length of the intracardiac device and are exposed, in use, to the blood flow.
