DEVICE AND METHOD FOR REDUCING HEART VALVE SIZE Russian patent published in 2013 - IPC A61F2/24 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine. Device contains loop-shaped element for size reduction, which has spiral construction, first support ring, located proximally, distal element in form of spiral loop, located distally, and second support ring between first support ring and distal element in form of spiral loop. First support ring and second support ring are made with possibility of location on opposite sides of fibrous ring of said heart valve and are connected with formation of part of spiral construction in form of spiral configuration. Second support ring has smaller diameter than distal element in form of spiral loop. Distal element is made with possibility of covering in fact all heart valve chords in such a way that second ring is made with possibility of changing position of said chords in direction to the centre of said valve when said element for size reduction is introduced with rotation into said heart, thus loop-shaped element for size reduction is made with possibility of ensuring reduction of size of heart valve fibrous ring after said introduction. Set for recovery and method of assistance in recovery or replacement of heart valve are described.

EFFECT: reduction of time for valve replacement or recovery.
