ABSTRACT:
A catamenial tampon is provided for precluding the bypass of menstrual fluid in use while simultaneously being easy to remove after use. The tampon comprises a generally cylindrical absorbent body having a ring slidably engaged around the body, the ring also being attached to the insertion end of the absorbent body. The ring comprises material which will expand when in place within the vagina to preclude menstrual fluid bypass. A withdrawal string is attached to the cylindrical body whereby, when the tampon is being removed by force exerted on the cylindrical body by means of the withdrawal string, the cylindrical body is disengaged from the ring and removed from the tampon followed by the attached ring.
