Title
(EN) MECHANICAL HEART VALVE PROSTHESIS
(FR) PROTHESE MECANIQUE DE VALVULE CARDIAQUE
Abstract
(EN)
Mechanical heart valve prostheses (10) are disclosed that inherently reduce the probability of thrombus formation by minimizing blood flow disturbance, high shear stress, and stagnation. The pivot configuration includes a recess (19), preferably in the housing (12), that has a profile which promotes smooth blood flow.
(FR)
L'invention concerne des prothèse (10) mécaniques de valvules cardiaques permettant de réduire de façon inhérente la probabilité de la formation de thrombi du fait qu'elles minimisent les perturbations du flux sanguin, les contraintes de cisaillement élevées, et la stagnation. Leur configuration en pivot comporte un évidement (19), pratiqué de préférence dans le logement (12), qui, de par son profil facilite un écoulement régulier du sang.
