Device for performing electrostimulation and/or pliotobiostimulation on tissue parts of the human body, in particular on the inner wall of the vagina, in which the device is inserted, comprising a substantially cylindrical body (1), formed by a plurality of intermediate annular elements (8, 9, 10, 11, 12) on top of one another with the formation of a longitudinal stacking. A pair of end annular elements (4, 6) is provided with a transversal wall (2, 3) causing the closing of the stacking and the formation of a longitudinal inner cavity (13). The device also comprises means for mutually connecting the adjacent annular elements imparting mechanical stability to the cylindrical body (1) and sealing to the inner cavity (13). At least one of said intermediate annular elements (8, 9, 10) is adapted to emit electric electrostimulation signals and at least one of said intermediate annular elements (11, 12) is adapted to emit photobiostimulation signals. To this end, the device includes at least one electrostimulation signal generator and at least one photobiostimulation signal emitter, an electronic control unit for controlling said signal generators and emitters according to a predetennined operating program and means for supplying power to said control unit and to said signal generators and emitters, control means (15) being provided for switching the device on and off.L'invention porte sur un dispositif d'électrostimulations et/ou de photobiostimulations de parties de tissu du corps humain, en particulier sur la paroi interne du vagin, dans lequel le dispositif est inséré. Celui-ci comprend un corps cylindrique (1), formé d'un empilement de plusieurs éléments annulaires intermédiaires (8, 9, 10, 11, 12). Les éléments annulaires situés aux extrémités (4, 6) sont pourvue d'une paroi transversale (2, 3), provoquant la fermeture de l'empilement et la formation d'une cavité intérieure longitudinale (13). Le dispositif relie les éléments annulaires adjacents, conférant une sta
