Embodiment Construction

[0047] heart and heart structure

[0048] refer to figure 1 , H refers to the heart, which includes four chambers: left ventricle LV, left atrium LA, right ventricle RV, and right atrium RA; and four valves: mitral valve, aortic valve, tricuspid valve, and pulmonary valve.

[0049] Each ventricle is defined by walls that expand and contract for pumping action, and each valve includes an annulus.

[0050] In this specification, the term cardiac structure refers to the walls of the ventricles and the annulus of the valves.

[0051] figure 1 The dotted line in shows the area Z that may be used for the connection of the intracardiac device according to the invention, which is used to restore the function of the heart structure if the function of the heart structure is not enough to fully perform the function it should perform. . It is obvious that the area Z shown here is for indication only, and the intracardiac device may be implanted in areas other than the area shown.

Abstract

An intracardiac device (101) 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 (83) and is attachable to a cardiac structure; the coils (83) are selected in material, number and dimension so as to allow an elastic elongation of the intracardiac device (101) higher than 10% of the rest length of the intracardiac device (101) and are exposed, in use, to the blood flow.

Description

technical field [0001] The present invention relates to intracardiac devices for restoring the elasticity of cardiac structures. [0002] In particular, the present invention relates to devices for the treatment of cardiomyopathy and valvular heart disease. Background technique [0003] To better understand heart disorders such as cardiomyopathy and valvular heart disease, the purpose of treatment, and what affects the heart, a brief description of heart structure and function is given. [0004] The heart comprises a number of chambers that communicate with each other and through valves and a system of veins and arteries. In the case in question, the heart consists of four chambers: the right atrium, left atrium, right ventricle, and left ventricle, and four valves: the mitral, aortic, pulmonary, and tricuspid valves. Human blood passes from the right atrium, from here through the tricuspid valve, to the right ventricle, and the right ventricle sends blood to the lungs thr...
