What does Thoratec Heart Mate II provide as a device?

The Thoratec HeartMate II is classified as a left ventricular assist device (LVAD), which is a mechanical pump used to support heart function and blood flow in individuals with advanced heart failure. This device is implanted to help the left ventricle pump blood to the rest of the body, thereby improving the patient's quality of life and extending survival in those who are not candidates for heart transplantation or waiting for a transplant.

As a left ventricular assist device, the HeartMate II is specifically designed for long-term support, making it different from total artificial hearts, which replace the entire heart, or temporary support systems, which are usually meant for short-term use. It does not provide biventricular support, as it is primarily focused on assisting the left ventricle alone. This specialized function is essential for clinical management of heart failure patients, allowing them to lead more active lives while managing their condition effectively.
