PROSTHETIC CARDIAC VALVE, METHOD OF PROSTHETIC CARDIAC VALVE TESTING FOR DYSFUNCTION AND RELATED DEVICE FOR IMPLEMENTATION THEREOF

摘要

FIELD: medicine; cardiology. ^ SUBSTANCE: said valve comprises a ring box and a number of indented leaves to be attached thereto. The ring box is supplied with an opened conductive element arranged therein or on its surface. Fastening indents for each leaf are interconnected in pairs with the conductive element contacting to the conductive element of the ring box. The method involves fitting the valve with a radiator and recording electromagnetic radiation within radio frequency band therefrom, as well as determining the dysfunction by frequency response deviation from the reference received from a standard valve. The device for valve testing for dysfunction comprises a receiving antenna representing a multi-turn spiral arranged on the external surface of the patient's body at the minimum distance between the valve and the antenna connected to a recording unit. ^ EFFECT: possibility to examine dysfunction of the valve in service. ^ 3 cl, 1 dwg
