Abstract
A catamenial device which is a tampon having a hollow or loosely packed central area and a forward end which flares open to a funnel configuration upon insertion into the vaginal tract of the user to cap the cervix and thereby direct menstrual fluid into the interior thereof. The tampon is removed by pulling a drawstring which is also a pursing string. The string first closes the forward end before exerting removal force on the tampon. Also, the body of the tampon is encased in a fluid barrier so that fluid is captured and retained within the tampon and absorption by the tampon from the vaginal wall is prevented.
