Potentially reversible female sterilization device

Contraceptive device comprising an obturator having a body with a cylindrical configuration, made of a flexible material and including two stabilizing deformable stiffeners or wings that can be folded back along the body of the obturator when unactivated, spreading out radially in a fitted situation in an isthmic part of a Fallopian tube, the two stabilizing deformable stiffeners or wings being in opposite positions so that a distal one of the two stabilizing deformable stiffeners or wings is situated to fit in the isthmic part of the Fallopian tube and a proximal one of the two stabilizing deformable stiffeners or wings is situated on edges of a tubal ostium, wherein the device further comprises, along the body, a plurality of projecting forms, having a ridged configuration, running along an entire length of said obturator body in a continuous manner from a tapered bulge of the proximal end to a spherical distal end of a head and having a dual function of blocking a tubal lumen and protecting tubal haustrations, the projecting forms accommodating themselves within alveoli formed in a body of the Fallopian tube and being in contact with some of mucosal folds or haustrations, causing deformation of the alveoli to block and obstruct spermatozoa and to close off other mucosal folds in order to protect their surface and ensure protection of other closed mucosal folds not in direct contact, the contraceptive function of the contraceptive device being reversible.
