Thoratec: Heartmate II

HeartMate II is Thoratec's first-line intermediate-to-chronic left ventricular assist device. Designed to dramatically improve survival and quality of life, the HeartMate II was developed with the goal of providing several years of circulatory support for a broad range of advanced heart failure patients. Its small size and quiet operation makes it suitable for a wider range of patients, including women and those of smaller stature.
