Abstract
A ventricle unloading device intended to be implanted inside a patient's blood vessel portion through which a blood flow circulates. The device includes: a stator, a rotor arranged around the stator, the rotor having a driving impeller and a impeller engine, the impeller being an unducted impeller aimed at rotating freely within the blood vessel portion, and a static anchoring element displaying a circular part which is configured to extend around the impeller. The circular part of the static anchoring element defines a circulation area intended to contain the entire blood flow circulating through the blood vessel portion, the activation of the rotor is a pulsatile activation, and the activation is synchronized with the patient's heart contraction.
