Abstract

The auxiliary artificial heart according to the main patent comprises by way of improvement a single-body flexible envelope connected to the single-body pump and which surrounds the heart, and whose elastic wall is adhesively bonded to the inelastic wall bordering the spaces corresponding to each ventricle, the inelastic covering being double, allowing elastic bags such as those existing in the armbands of blood-pressure measurement devices to be inserted between the two sheets, opposite the cardiac cavities to be assisted.

Description

"COEUR ARTIFICIEL AUXILIAIRE "
La présente invention concerne un coeur artificiel auxiliaire selon le brevet principal 8306330, qui est caractérisé par une pompe monocorps sans valve ni soupape, dont le volume intérieur communique avec la cavité entre coeur et péricarde."AUXILIARY ARTIFICIAL HEART"
The present invention relates to an auxiliary artificial heart according to main patent 8306330, which is characterized by a unibody pump without valve or valve, the internal volume of which communicates with the cavity between heart and pericardium.

Une variante du procédé consiste à entourer le coeur d'une enveloppe souple, mais inextensible doublée à l'intérieur d'une membrane souple, extensible, dont elle est séparée par un espace cloisonné de façon à être partagé en deux, l'un correspondant au V.G., l'autre au V.D.A variant of the method consists in surrounding the core with a flexible, but inextensible envelope lined inside a flexible, extensible membrane, from which it is separated by a partitioned space so as to be divided in two, one corresponding at VG, the other at VD

Ces espaces aboutissent à deux orifices séparés.These spaces lead to two separate orifices.

Ces orifices sont abouchés à deux branches d'un tube en "Y", la branche unique étant abouchée à la pompe, et étant munie d'un volet distributeur permettant de moduler le débit entre les deux autres branches.These orifices are connected to two branches of a "Y" tube, the single branch being connected to the pump, and being provided with a distributor flap allowing the flow between the two other branches to be modulated.

I1 est ainsi possible d'assister soit uniquement le V.G., soit uniquement le V.D., soit les deux ensemble, en fonction de leur degré d'insuffisance respectif, tout en préservant les autres cavités de toute compression inutile. It is thus possible to assist either only the V.G., or only the V.D., or both together, according to their respective degree of insufficiency, while preserving the other cavities from any unnecessary compression.

Cette compression peut se faire à l'aide de liquide ou de gaz, ce dernier présentant une inertie moindre que le liquide.This compression can be done using liquid or gas, the latter having less inertia than liquid.

Cette solution se comporte comme un véritable coeur artificiel pouvant fonctionner même en cas d'insuffisance cardiaque au dernier stade, et ce de façon durable.This solution behaves like a real artificial heart that can function even in the event of heart failure at the last stage, and this in a sustainable way.

Elle évite certains des problèmes de la solution péricardique : résorption de liquide propulseur, non sélectivité de l'assistance, risque d'infection du péricarde, risque de fuite du liquide propulseur, tout en laissant subsister un risque d'irritation du péricarde, qui nécessitera peut etre un traitement anti-inflammatoire. It avoids some of the problems of the pericardial solution: absorption of propellant liquid, non-selectivity of the assistance, risk of infection of the pericardium, risk of leakage of the propellant liquid, while leaving a risk of irritation of the pericardium, which will require can be an anti-inflammatory treatment.

La paroi élastique est collée à la paroi non élastique en bordure des espaces correspondant à chaque ventricule.The elastic wall is glued to the non-elastic wall at the edge of the spaces corresponding to each ventricle.

L'enveloppe non élastique étant double permet l'introduction entre les deux feuillets de sacs élastiques, tels ceux existants dans les brassards à tensiomè- tre, en regard des cavités cardiaques à assister.Since the non-elastic envelope is double, it allows the introduction between the two sheets of elastic bags, such as those existing in blood pressure cuffs, facing the cardiac cavities to be assisted.

L'enveloppe extérieure peut être rigide avec un système d'ouverture et de fermet permettant une mise en place rapide, la membrane élastique étant simple, les bords collés, ou doubles, simplement fixée en regard des cavités à assister.The outer envelope can be rigid with an opening and closing system allowing rapid installation, the elastic membrane being simple, the edges glued, or double, simply fixed opposite the cavities to be assisted.

L'enveloppe extérieure comporte un secteur de recouvrement permettant une adapta tion à toutes les tailles de coeur, avec un système de coeur, avec un système de fixation de la double membrane élastique permettant d'ajuster la prothèse à tout taille ou toute conformation de coeur.The outer casing has a covering sector allowing adaptation to all sizes of heart, with a heart system, with a system for fixing the double elastic membrane allowing the prosthesis to be adjusted to any size or any conformation of the heart. .

L'enveloppe selon l'invention peut etre adaptée à tout système destiné à assiste le coeur par tout moyen s'apparentant au massage cardiaque. The envelope according to the invention can be adapted to any system intended to assist the heart by any means akin to cardiac massage.
