Abstract
Abstract A heart massager for substernal heart massage is disclosed. The heart massager has a heart-contacting member having a surface which is at least partially concave for contacting the heart, cushioning on the surface of the contact member, and a handle attached to the heart-contacting member for manually manipulating the massager. The partially concave surface allows the heart-contacting member to conform to the shape of the heart. The handle is substantially upright with respect to the surface of the heart-contacting member. The handle is significantly offset from a central portion of the heart-contacting member in the region where it attaches to the member. The cushioning covers substantially the entire surface of the heart-contacting member so as to form a solid surface.
