Abstract
The invention relates to a sequential pneumatic control device, supplied with electric energy, for a total cardiac prosthesis (4) formed by a biventricular monobloc assembly with pneumatic operation, this device being contained in at least one sealed case (10) implantable in the human body; this device comprises an enclosure forming a drive fluid reserve defined by a wall at least partially flexible (12) subjected to the internal pressure of the human body, whereby the initial pressure of the drive fluid is made permanently dependent on said internal pressure of the body, which serves as a reference pressure.
