Abstract
A total artificial heart having a rotor with an impeller, wherein the rotor is mounted within a pump housing on a hollow shaft. The rotor is magnetically driven to produce rotary motion of the impeller for pumping blood. The motor is disposed within the pump housing such that axial translation within the housing acts as a shuttle valve to alternate flow between pulmonary and systemic circulation.
Claims13
A method for pumping blood in a patient comprising:
- providing a pump comprising a housing having an impeller rotatably and translatably housed within a bore of the housing;
- wherein the pump is configured to rotate the impeller in a first axial position to pump venous blood from venous circulation to a pulmonary circulation and to rotate the impeller in a second axial position to pump blood from a left atrium to arterial circulation.
A method for pumping blood in a patient comprising:
- implanting a pump comprising a housing having first, second, third and fourth vascular connectors, and an impeller rotatably and translatably mounted housed within a bore of the housing;
- and
- connecting the first vascular connector to a left atrium (LA), the second vascular connector to an aorta (AO), the third vascular connector to a right atrium (RA), and the fourth vascular connector to a pulmonary artery (PA);
- wherein the pump is configured to rotate the impeller in a first axial position to pump venous blood from the right atrium to the pulmonary artery and to rotate the impeller in a second axial position to pump blood from the left atrium to the aorta.
