A cardiac massage device (10) deployable by a minimal invasive procedure for applying pulsatory pressure to a ventricular wall of a heart includes an inflatable receptacle (12) deployable between a closed insertion state and an open state. The open state of the device is configured for substantially enveloping the ventricular portion of the heart. A plurality of support elements (14) are mechanically linked to the inflatable receptacle so as to deploy the inflatable receptacle to its open state. Preferably, the support elements are implemented as flexible rods resiliently biased to return to a pre-defined shape and a retaining mechanism (22) is provided. Also described is a deployment technique employing suction clamping and a two-stage trocar (40, 42). |
