1. A modular prosthetic valve device comprising a plurality of modules and a self-assembled element, wherein said modules are capable of being assembled to form said valve device in the body, if necessary, using said self-assembled element. The device according to claim 1, characterized in that said plurality of modules comprises a plurality of valve sections, each of said valve sections having a first end, a second end, a base and a peak, said valve sections being continuously assembled in an unassembled state and can be collected in the working configuration using the specified self-assembly element, while the specified number of valve sections has a circular axis and a vertical axis, and the specified circular axis extends from the first end of the first valve section at the indicated row to the second end of the last valve section of the specified row, and the indicated vertical axis is determined by the base-to-vertex configuration of said valve sections, wherein said self-assembled element is attached along said circular axis. 3. The device according to claim 1, characterized in that said plurality of modules comprises a valve component, said valve component comprising a substantially flat leaf structure in an unassembled state having a first end and a second end, a base-to-vertex configuration, a rotary axis and a vertical axis axis, wherein said circular axis extends between said first and second end, and said vertical axis is defined by said base-to-vertex configuration of said unassembled sash substructure, pr1.
