Devices, systems, and methods for a valve replacement

Abstract

Disclosed are valve replacement devices, systems, and methods. Valve replacement devices may comprise one- or two-piece systems comprising a receiver body (also called an adapter) and a valve assembly with replacement leaflets attached to and located within the receiver body. In two-piece systems, the valve assembly may be removable from the receiver body such that both can be delivered together or separately, and the receiver body may remain implanted while the valve assembly may be removed and replaced. Also described are devices, systems, and methods related to delivering, removing, and replacing a valve replacement. Such delivery methods may include transseptal insertion of a new minimum leaflet structure, and securement of the valve replacement using several securement type (e.g., supra-annular, sub-annular, radial, leaflet securement, etc.). Also described is a braided helical design that mimics the heart's natural movement, and a flange structure for assisting the functioning of the valve replacement.
