A left ventricular cardiac assist pump, including an inlet opening (18) and a discharge opening (20) aligned in an axial direction, the pump including a casing (11) spaced from a stator (13) and a rotor (12) comprising an impeller (16) and a shaft (17), with at least one connecting spacer (14) connecting the casing (11) and the stator (13), the impeller (16) being configured to direct the blood towards the casing (11) and the discharge opening (20), whereby blood flows through the pump principally between the casing (11) and the rotor-stator assembly (15). The casing (11) and the connecting spacers (14) are each formed of a mesh structure (125, 126) made of a resilient shape memory material. |
