A device for epicardial support and/or the assuming of cardiac activity having a double membrane (1) consisting of an elastic inner membrane (2) and a non-expandable outer membrane (3) as well as a closed cavity (4) formed therebetween which can be inflated and deflated by means of a fluid exhibiting a first chamber (6) allocated to the right ventricle (5) and a second chamber (8) allocated to the left ventricle (7). With the objective of further developing a device of the type as indicated at the outset so that same provides for simple device operability while maintaining the advantage of being able to augment only one ventricle, it is provided for the first chamber (6) and the second chamber (8) to be connected to one another by means of at least one valve (9) in a dividing wall (10) separating the two chambers (6, 8).
L'invention concerne un dispositif d'assistance épicardique et/ou de reprise de l'activité cardiaque. Ce dispositif comprend une membrane double (1) présentant une membrane interne élastique (2) et une membrane externe (3) non extensible et, entre ces deux membranes, une cavité (4) fermée, gonflable à l'aide d'un fluide et dégonflable. Cette cavité comprend une première chambre (6) associée au ventricule droit (5) et une deuxième chambre (8) associée au ventricule gauche (7). L'invention vise à améliorer le dispositif de type susmentionné de manière à faciliter l'utilisation du dispositif tout en conservant l'avantage d'une augmentation possible d'un seul ventricule. A cet effet, la première chambre (6) et la deuxième chambre (8) sont en communication par au moins une valve (9) placée dans une paroi de séparation (10) qui sépare les deux chambres (6, 8).
