ABSTRACT:
A catamenial tampon comprising an elongated core of conventional highly absorbent fibrous material which is relatively incompressible and enclosed by a sheath of open-celled resilient foam. The foam transmits by capillary action, fluids from the exterior of the tampon inwardly to the fibrous core. The reticulated foam sheath also isolates the core from the effects of compression which may be caused by muscular activity or by withdrawal.
