Title
(EN) A CARDIAC PUMP
(FR) POMPE CARDIAQUE
Abstract
(EN)
A cardiac pump (1) comprising a cardiac pump housing (7), a cardiac pump rotor (8), and a bearing assembly (23), the bearing assembly (23) being configured to support the cardiac pump rotor (8) within the cardiac pump housing (7) for rotation about a rotational axis (A-A) of the rotor (8), wherein the cardiac pump rotor (8) comprises a tip profile having rotational variance about the rotational axis (A-A).
(FR)
Une pompe cardiaque (1) comprenant un boîtier de pompe cardiaque (7), un rotor de pompe cardiaque (8) et un ensemble palier (23), l'ensemble palier (23) étant conçu pour supporter le rotor de pompe cardiaque (8) à l'intérieur du boîtier de pompe cardiaque (7) pour une rotation autour d'un axe de rotation (A-A) du rotor (8), le rotor de pompe cardiaque (8) comprenant un profil de pointe ayant une variance de rotation autour de l'axe de rotation (A-A).
