Abrégé
(EN) This invention is a minimally invasive device for performing direct cardiac massge including an inflatable bladder (2) mounted on a rigid inflation tube (3). The rigid inflation tube is used to push the bladder into the sternocostal space through an incision in the upper abdomen just below the xiphoid process. After inserting into the sternocostal space, the bladder is repeatedly inflated and deflated to massage the heart and provide the blood flow.
