AORTIC VALVE PROSTHESIS Russian patent published in 2019 - IPC A61F2/06 A61F2/24 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment. Aortic valve assembly comprises carcass able to receive compressed configuration and expanded configuration. Frame comprises an inflow section, an outflow section and a connecting section located between the inflow section and the outflow section. Influx section has multiple legs, which radially protrude outwards in expanded configuration. Connecting section has higher flexibility than inflow section. Assembly module of leafs and skirt has several flaps connected to connecting section, valve skirt extending from flaps towards section of frame influx, as well as a section of the collar. Legs and section of the cuff in the expanded configuration form the cuff to provide contact with the native aortic ring. Each of the plurality of legs has a first portion which extends vertically from the inflow portion along the same plane as the carcass, and then passes through the first curved into the second portion, which extends radially outward and perpendicular to the first portion, after which it passes through a second bend in third part, which is perpendicular to second part. End of third part is made in the form of eye. Embodiments of the aortic valve assembly design and embodiments of the aortic valve assembly deployment method are disclosed.

EFFECT: technical result consists in providing the possibility of substitution of calcinated native valves.
