An improved condom is provided by coating the inner and or outer surface of the condom base with a dissolvable element containing an agent material for delivering the agent material during sexual intercourse. The dissolvable element is made of dissolvable polymer material and/or complex carbohydrate material which are food grade materials and have selected dissolution properties, such that it remains in substantially solid form before use, and dissolves due to human body temperatures and moisture during use to release the agent material in a desired timed release and dosage. The dissolvable element is preferably a film made of polyvinyl alcohol, polyethylene oxide, hydroxypropyl methyl cellulose and/or carboxymethyl cellulose. The dissolvable element may be formed as a single layer of film or a laminate of different film layers for compound release properties. The dissolvable element is at least partially foamed using inert gases, such as nitrogen, to adjust its dissolution properties. The agent material can be selected from the group consisting of spermicides, anti-infectives, anti-inflammatories, antibodies, steroids, vasoactive agents, sensory modifying agents, anti-oxidants, preservatives, plasticizers and mixtures thereof. The condoms can be used for sexual intercourse involving penis with vagina, rectum or mouth.

A contraceptive diaphragm has a cup-shaped body molded from a thermoplastic or thermosetting material, and a rim formed with the diaphragm body having a thickness and an inner core structure sufficient to provide a desired bending resilience for use of the diaphragm without any metal spring therein. The thermoplastic or thermosetting material is preferably a silicone rubber. In one embodiment, the rim is molded with a solid inner core structure with a circular cross-section of between 0. 060 to 0. 375 inch outer diameter. In another embodiment, the rim is formed by an outer layer molded around an inner core in the form of a plastic, injection- or compression-molded ring. The molded plastic ring is preferably made of an acetal plastic material with an outer diameter of between 0. 040 to 0. 250 inch. The plastic ring may have two or more cutout portions formed spaced apart along its circumference for defining flexing points on the diaphragm rim.

A dissolvable element containing an agent material is used for local administration of the agent material in an internal body area. The dissolvable element is made of dissolvable polymer material and/or complex carbohydrate material which are food grade materials and have selected dissolving properties, such that it remains in substantially solid form before use, and dissolves due to human body temperatures and moisture during use to release the agent material in a desired timed release and dosage. As a contraceptive, the dissolvable element is preferably a film made of polyvinyl alcohol, polyethylene oxide, hydroxypropyl methyl cellulose and/or carboxymethyl cellulose. The dissolvable element may be formed as a laminate of different film layers for compound release properties, or it may be ground into particles and incorporated in a tampon or suppository. The dissolvable element may be foamed as a means for increasing its dissolution rate. The agent material can be a spermicide, such as Nonoxynol-9, and/or a drug or medication.
