Abstract
A heart pump includes a rotative impeller partly inserted into the systemic ventricle, this rotative impeller being equipped with a membrane sutured to the outer wall of the heart in such a way as to secure the rotative impeller to the wall of the heart, a housing arranged inside the systemic ventricle in such a way as to draw up then discharge blood, a motor connected to the housing and arranged partly outside the systemic ventricle in such a way as to facilitate maintenance; an integrated management unit in the epigastric region including a power supply and a rotative impeller control unit; and a wired link between the management unit and the rotative impeller.
Claims19
A heart pump configured to be inserted, in an implanted state, partly into a systemic ventricle of a heart, through a wall of the heart, the heart pump comprising:
- a housing comprising at least one first opening on its side wall to allow for the drawing up of blood directly from the systemic ventricle, and a second opening configured to be inside the systemic ventricle in the implanted state for the discharge of blood directly inside the systemic ventricle through sigmoid valves of the systemic ventricle;
- an impeller inserted inside the housing;
- a motor connected to the housing at an opposite side of the second opening;
- a sealing and fixing membrane fastened to and around the motor;
- a management unit comprising a power supply, and an impeller control unit;
- a wired link between the management unit and the impeller;
- and
- an activity sensor configured to collect cardiac activity to synchronize an operation of the impeller with electrosystolic activity of the heart.
A method of regulating blood flow in a heart by a heart pump, the method comprising:
- providing a heart pump configured to be attached to the heart and configured to be inserted, in an implanted state, partly into a systemic ventricle of the heart, through a wall of the heart, the heart pump including:
- a housing comprising at least one first opening on its side wall in such a way as to allow for the drawing up of blood directly from the systemic ventricle and, a second opening for the discharge of blood directly inside the systemic ventricle through sigmoid valves of the systemic ventricle,
- an impeller inserted inside the housing,
- a motor connected to the housing at opposite side of the second opening,
- a sealing and fixing membrane fastened to and around the motor,
- a management unit comprising a power supply, and an impeller control unit,
- a wired link between the management unit and the impeller, and
- an activity sensor configured to collect cardiac activity to synchronize an operation of the impeller with electrosystolic activity of the heart;
- collecting cardiac activity using the activity sensor to synchronize an operation of the impeller with electrosystolic activity of the heart by identifying a start of electrical activation and synchronizing the impeller with the opening of the valves;
- and
- controlling a speed and an operating time of the pump in order to regulate blood flow when the heart pump is attached to the heart based on predetermined control laws or based on an automatic control instruction relating to cardiac activity and using the activity sensor.
