Problems solved by technology

However, the disadvantage of this cardiac prosthesis is that the diastolic duration must be equal to the systolic duration, which does not allow for physiological
In addition, such single-actuator heart prostheses run the risk of pumping the atria without properly filling the ventricles or pumping out fast enough to maintain the correct pressure

Embodiment Construction

[0038] exist figure 1 A known prosthesis P schematically shown in , is used to replace the natural left and right ventricles of a diseased heart (not shown) after resection of the left and right natural ventricles. The cardiac prosthesis P should be able to be accommodated at least approximately in that part of the pericardial cavity left empty by the resection of the native ventricle.

[0039] as in figure 1 As shown schematically in , the cardiac prosthesis P includes:

[0040] - a rigid body 1 in which is arranged an artificial left ventricle 2 comprising a flexible membrane 3 which divides said artificial ventricle 2 in a sealed manner into a chamber 4 for blood circulation and a chamber for hydraulic fluid Chamber 5, said blood chamber 4 for connection on one side to the native left atrium OG communicating with the pulmonary vein VP and on the other side to the aorta AO;

[0041] - a hydraulic actuator 7, for example of the positive displacement motor pump type, which ...

Abstract

Implantable one-piece heart prosthesis. According to the invention, the prosthesis comprises a main hydraulic actuator (13t) arranged between the artificial ventricles (2 and 8) and designed to actuate, with desired flow rates, one (8) of said artificial ventricles, and also an auxiliary hydraulic actuator (7t) designed to correct the diastolic and systolic flow rates of the other (2) of said ventricles.

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...
