  • Publication number: 20050061328
    Abstract: A female condom having a highly elastic resilient pouch portion is able to stretch from an original contracted configuration into an elongated configuration and then return to the original contracted configuration. The pouch may be fashioned with regular convolutions that act in a spring-like manner for biasing the condom into the contracted configuration. Elastic biasing members may be incorporated into the construction of the condom for providing or augmenting the spring-like action of the condom. The condom of the invention may include a contoured V-shaped outer frame which also may have a spring bias incorporated. The outer frame may flex so as to better retain contact with the anatomy of the female when the condom is inserted in the vagina. A retention sponge is located in the closed end of the pouch and can serve as a resilient elastic member in addition to or in place of the pouch.
