Abstract

Se provee una de válvula cardíaca de bioprótesis artificial (100) y un método de fabricación de la misma. La bioprótesis artificial de la válvula cardíaca (100) comprende: un marco de válvula (1), una valva de válvula (2) y una estructura auxiliar de válvula. El prospecto de la válvula (2) está conectado a la estructura auxiliar de la válvula, la estructura auxiliar de la válvula está conectada al marco de la válvula (1). Tanto el prospecto de la válvula (2) como la estructura auxiliar de la válvula están hechos de biomateriales. El marco de la válvula (1) está formado integralmente por un material elástico, y la estructura auxiliar de la válvula está preestablecida con una marca de sutura. La bioprótesis de la válvula cardíaca mejora la biocompatibilidad con el cuerpo humano, reduce la altura total de la válvula, acorta el tiempo de sutura y disminuye la posibilidad de trombos o adherencias bacterianas. Además, la bioprótesis artificial de la válvula cardíaca se realiza mediante un procesamiento simple, tiene un excelente cumplimiento con el tejido cardíaco y tiene una vida útil prolongada de la válvula.
