ABSTRACT:
The invention features an innovative vaginal sponge contraceptive device that has active spermicide. The active spermicide allows the device to be used instantly upon removal from its sealed packet. The sponge is of a sufficient size such that swelling agents, contained therein, maintain the sponge in pressured contact with the vaginal wall to prevent slippage from cervical contact. A low level of spermicide allows for effectiveness without irritation. A deodorant, contained in the sponge, provides for continuous use over a 24-hour period.
