Centrifugal Pump Technology

As blood is drawn into the DuraHeart pump, a paddlewheel-like component (impeller) forces the blood toward the outside walls and expels it through an opening.

Congestive Heart Failure (CHF)

Left Ventricular Assist System

A class of medical devices that helps the left side of the heart pump oxygen-rich blood through the body. Also called a Left Ventricular Assist Device.


Acronym for Left Ventricular Assist Device. Same as Left Ventricular Assist System (LVAS).


Acronym for Left Ventricular Assist System. A device designed to help the left side of the heart to pump blood to the body.

Magnetic Levitation

Through electromagnetics and position sensors, the impeller is suspended within the blood chamber.

Mechanical Circulatory Support (MCS)

A type of treatment used for end-stage heart failure patients. As the population continues to age and heart failure rates continue to grow, MCS is becoming a more frequent alternative for patients.


Venous or arterial occlusion is a state of being closed or shut.


Passed through the skin.

Pulmonary Artery

Receives blood from the right ventricle and carries it to the lungs to be “refueled” with oxygen.

Right Atrium

Right Ventricle

Receives blood from the right atrium and pumps it through the pulmonary artery to the lungs to pick up oxygen.


Occurs when a blood clot forms and then breaks off and travels to another part of the body via the bloodstream.
