Abstract
An everting toroid for use in delivering a powdered, fluid, or aerosolized pharmaceutical composition, or other composition, to an internal body cavity, such as the urethra, or other cavity, is contained within a tubular housing and may be extended therefrom and retracted back into the tubular housing. The composition may be distributed on the surface of the everting toroid when made from an impermeable membrane, contained within the toroid when made from a permeable membrane, or may be injected through the lumen thereof via an aerosol wand which releases the composition as the toroid and/or wand are withdrawn from the cavity.
