FIELD: medicine.SUBSTANCE: group of inventions relates to medicine. Intracardiac device for recovery of functional elasticity of cardiac structures, accumulating energy from cardiac structures and transmitting energy to cardiac structures during cardiac cycle, has elongated shape, is wound in spirals along specified section and can be fixed to cardiac structure. Spirals are selected by material, number and sizes in such a way as to make it possible for intracardiac device to be elastically elongated within the range from 10% to 50% of the length of intracardiac device in the state of rest, and are subjected to impact by blood flow in the process of exploitation. Device contains elongated link, made from metal wire of springs, wound in spirals along said specified section. At least one link is capable of direct fixation to cardiac structure, is fixed on elongated link, and has elongated shape, and is located near elongated link and along it. Fixed link includes tube from metal net, crisscrossing with said spirals. Tube is capable of stretching. Described is constructive variant of intracardiac device and holding instrument for intracardiac device.EFFECT: inventions make it possible to minimise response of cardiac structures to foreign body in cardiac cavity.10 cl, 27 dwg |
