ABSTRACT:
A vaginal spermicide distributing membrane comprises a relatively thin flexible membrane having a plurality of integral rings of thicker dimension on one or both sides thereof. Each ring can have a depression along its surface that functions as a receptacle for spermicide. The rings provide sufficient resistance to deformation so that when the membrane is flexed for insertion in the vagina, it will tend to assume a planar shape and be held in contact with the vaginal mucosa. The rings keep the device properly positioned and function as successive barriers to sperm migration. Loops provided along the periphery of the membrane assist in its insertion and removal.
