A reversible leave in contraceptive device includes an obturator having a body with cylindrical configuration, made of a flexible material and including two stabilizing deformable stiffeners that can be folded back along the obtorator body when unactivated, spreading out radially in a fitted situation in the isthmic part of the Fallopian tube. The stiffeners are in opposite positions so as to fit on one side in the isthmic part of the tube (for the distal side) and, on the other (proximal end) on edges of a tubal ostium. A plurality of projecting forms, having a ridged configuration, run along the entire length of the obturator body in a continuous manner from a tapered bulge of the proximal end to a spherical distal end of the head, and block the tubal protect tubal haustrations. The forms cause deformation of the alveoli to block spermatozoa and close off other mucosal folds. |
