Dual-Pulsation Bi-Ventricular Assist Device

A ventricular assist device comprising:

• a sac for wrapping around a portion of a heart, the sac having one or more inflatable chambers for compressing the heart when the chambers being inflated;
• and
• a manifold having a first and a second pathway intersecting with each other at an angle, the first pathway being completed embedded in the aorta with the second pathway leading toward outside of the aorta,
• wherein during a systolic phase the inflatable chambers inflate while blood flows out of the aorta through the second pathway of the manifold, and during a diastolic phase the inflatable chambers deflate while blood flows into the aorta through the second pathway of the manifold.
