Description

technical field

[0001] The invention relates to an implantable integral heart prosthesis. Background technique

[0002] From the document US-5135539, a cardiac prosthesis implantable in the pericardial cavity of a patient is known, which is capable of replacing the natural left and right ventricles of the patient after resecting them, and comprising:

[0003] - a rigid body in which are arranged an artificial left ventricle and an artificial right ventricle, each of these artificial ventricles comprising a flexible beating membrane:

[0004] a flexible pulsating membrane capable of beating under the action of hydraulic fluid, and

[0005] A flexible pulsatile membrane is arranged in a cavity which is divided in a sealed manner by said membrane into two chambers, one for blood circulation and the other for said hydraulic fluid, the blood chamber of the artificial left ventricle It is used to connect with the natural left atrium and aorta, while the blood chamber of the arti...
