Non-invasive pulsatile circulatory assistance device (500, 600) that favors the circulation of a blood volume in the body of an individual, comprising: - a flexible multilayer structure (100) intended to be applied on at least a part of the body of the said individual, said structure comprising a flexible inner layer (102) on the side of the body of said individual and a more rigid outer layer (104), - pulsation means (200, 300, 400), attached to said multilayer structure (100) so that the set structure + pulsation means is tight, and that they create pulsation waves between said internal (102) and external layers (104) by means of a fluid, called pulsation, the said multilayer structure comprising means for guiding each of said pulsations progressively in the direction of venous return into the body of said individual along said body part of said individual suitable when said structure (100) is disposed on said body part of said individual, said means comprising a gelatinous and / or granular fluid that is contained in an intermediate layer (106) between the outer layer (104) and the inner layer (102) that performs the progressive propagation of each of the pulsations in the direction of venous return along said structure (100) and the multilayer structure (100) comprises an intake opening (114) of the fluid of pulsation that comes from the pulsation means (200) between the internal (102) and external (104) layers.Dispositivo de asistencia circulatoria pulsátil no invasivo (500, 600) que favorece la circulación de un volumen sanguíneo en el cuerpo de un individuo, que comprende: - una estructura multicapa flexible (100) destinada a ser aplicada sobre al menos una parte del cuerpo del citado individuo, comprendiendo la citada estructura una capa interna flexible (102) en el lado del cuerpo del citado individuo y una capa externa más rígida (104), - medios de pulsación (200, 300, 400), unidos a la citada estructura multicapa (100) de modo que el conjunto estructura +
