Pulsatile and non-invasive device for circulatory and haemodynamic assistance

Abstract

The present invention relates to a non-invasive pulsatile circulatory assistance device encouraging the circulation of a volume of blood in a subject's body, the device being characterized in that it comprises: a flexible multilayer structure for applying against at least a portion of said subject's body, said structure comprising a flexible inner layer (102) beside said subject's body and a more rigid outer layer (104); and means for pulsating connected to said multilayer structure in such a manner that the assembly comprising the structure plus the pulsation means is leaktight, the device being characterized in that said pulsation means are adapted to create pulsations between said inner and outer layers by means of a fluid referred to as a “pulsation” fluid, each of said pulsations propagating progressively in the venous return direction along said portion of said subject's body when said structure is placed on said portion of said subject's body.
