Resumen
The invention relates to a teleoperated active annuloplasty system which can be used for the controlled, progressive, reversible and postoperative treatment of mitral insufficiency and other cardiovascular pathologies that can be corrected with the use of annuloplasty rings. The invention is based on the use of a shape-memory actuator ring which can be heated using external devices in order to activate the shape-memory effect which produces the geometric change intended to reduce mitral insufficiency. The prosthesis includes control electronics which receive external commands and act accordingly. The inventive means enable reversible, progressive step-by-step actuation, thereby providing a more controlled method generating less haemodynamic instability and intended for the treatment of various valve diseases.
