The HeartMate II ™ and HeartMate 3™ VADs pump blood by spinning and
propelling blood forward. They pull blood out of the heart and push it back
out to the body. The blood does not leave the body. There is an electrical
cord that comes out of the skin and gives the pump power and controls how
it works. The devices can fit in large children, teenagers, and adults. They can
be used for patients who will get a heart transplant or in some patients who
will not get a heart transplant.
