There are many significant advantages of the Jarvik 2000® compared to larger VADs. The Jarvik 2000 is small enough to fit inside the left ventricle which is not the case with larger VADs. Larger VADs also require creation of a “pump pocket” which creates a site for discomfort and possible infection. The Jarvik 2000 does not require a pump pocket because of its small size. With only one moving part, it is also totally silent.
