    摘要： The present invention provides a direct cardiac compression device for individualized support at different locations around the heart, the device comprising: a housing shaped to conform to the shape of the heart and to surround the heart; two or more active chambers positioned adjacent to the housing, wherein the two or more active comprise one or more right active chambers positioned on the right ventricle side of the heart and one or more left active chambers positioned on the left ventricle side of the heart, wherein the two or more active chambers are designed to conform to the shape of the heart, each active chamber comprising an inner membrane sealingly attached along its periphery to the housing and an active fluid individually supplied thereto; a right input connection in fluid communication with the one or more right active chambers to ingress the active fluid into each of the one or more right active chambers; a left input connection in fluid communication with the one or more left active chambers to ingress the active fluid into each of the one or more left active chambers, and a driver in fluid communication with each of the right input connection and the left input connection to individually and periodically ingress and egress the active fluid therefrom, wherein the active fluid individually inflates the one or more right active chambers and the one or more left active chambers to compress the heart.
