Abstract:
1. A non-invasive pulsatile circulatory assistance device assembly facilitating a circulation of a volume of blood in a subject's body, wherein the device comprises: a flexible multilayer structure for applying against at least a portion of said subject's body, said structure comprising a flexible inner layer beside said subject's body and a more rigid outer layer, wherein the inner layer comprises, on at least one portion thereof, a cavity between a microporous wall for putting into contact with the subject's skin and a wall beside the outer layer, said cavity being arranged to receive or convey a substance for application to said subject's skin through said microporous wall; and means for pulsating connected to said multilayer structure in such a manner that the assembly comprising the structure plus the means for pulsating is leaktight, and creating pulsation waves between said inner and outer layers by means of a pulsation fluid, said multilayer structure including means for guiding each of said pulsations progressively in the venous return direction towards an inside space of said subject's body along said portion of said subject's body when said structure is placed on said portion of said subject's body, wherein the means for guiding the pulsations, comprise a gelatinous or granular fluid between said outer and inner layers, performing a progressive propagation of each of the pulsations to propagate progressively in the venous return direction along said structure.
