ATRIOVENTRICULAR VALVE STENT WITH NATIVE VALVE FOLD AND HOLD MECHANISM Russian patent published in 2020 - IPC A61F2/24 

FIELD: medical equipment.

SUBSTANCE: atrioventricular valve stent has tubular shape with subannular front side, subannular posterior side and subannular lateral sides. Subannular front side comprises self-releasing clamping component for capturing the leaf of native valve, forming direct extension of subannular front side, if the stent is folded, and is bent if the stent is in the unfolded state. Clamping component forms an integral part of the stent. Each subannular lateral side has greater length than subannular front side if stent is in unfolded state.

EFFECT: technical result consists in improvement of reliability of native valve blocking in atrioventricular stent implantation.
