Prosthetic heart valves and devices, systems and methods for prosthetic heart valves

摘要

Described herein is a unique sutureless heart valve that includes a deployment mechanism having a plurality of fasteners. The plurality of fasteners may be actuated at least two states: a disengaged state wherein said plurality of fasteners are retracted, and an engaged state wherein said plurality of fasteners are extended; and further comprising a deployed state wherein said plurality of fasteners, when extended, are irreversibly locked such that said heart valve is securely deployed at the target surgical site. The valve deployment mechanism comprises a ring assembly comprising a first annular member onto which said plurality of fasteners are associated and a second annular member peripheral to said first annular member and comprising a series of windows through which individual fasteners of said plurality of fasteners project.

1. A sutureless heart valve for use in heart valve replacement surgery at a target surgical site, the sutureless heart valve comprising
a valve component that promotes unidirectional blood flow; and a valve deployment mechanism outwardly associated with said valve component, said valve deployment mechanism comprising a first annular member onto which a plurality of movable fasteners are associated and movable to at least two states: a disengaged state wherein said plurality of fasteners are retracted; and an engaged state wherein said plurality of fasteners are extended; wherein the plurality of fasteners move to the engaged state by rotating the first annular member at the target surgical site in a first direction such that the plurality of fasteners catch surrounding, tissue and return to the disengaged state when rotating the first annular member in a second direction opposite to the first direction; and wherein said valve deployment mechanism comprises a deployed state wherein said plurality of fasteners, when extended, are rigidly irreversibly locked such that said heart valve is securely deployed at the target surgical site.
