Abstract

Настоящее изобретение относится к искусственному клапану, содержащему створки в сборе, имеющие по меньшей мере одну створку (3), прикрепленную к опорному элементу (2), причем створка имеет свободный край (5), который может перемещаться между первым положением, в котором свободный край отклоняется от поверхности (700) закрывания так, чтобы биологическая жидкость могла протекать через клапан, и вторым положением, в котором свободный край примыкает к поверхности закрывания для закрывания клапана, причем створка без пульсирующей нагрузки на клапан может образовывать высоту Н смыкания более 0,1 мм по длине свободного края. Такой искусственный клапан обеспечивает надлежащие характеристики в течение продолжительного времени и может изготавливаться с использованием различных материалов створок. Изобретение также относится к створкам в сборе для использования в искусственном клапане и к способам изготовления искусственного клапана, включая изготовление створок в сборе.
