Abstract
The present technology provides intravaginal devices designed to deliver lubricants to the vagina for a sustained period of time. The intravaginal devices include a first segment comprising an outer surface and a lumen containing a lubricant, wherein the first segment is configured to deliver the contents of the lumen to the outer surface, and the first segment comprises a polymer selected from the group consisting of a hydrophilic, semi-permeable elastomer and a hydrophobic elastomer. The lubricant may be an aqueous lubricant. The present technology further provides an intravaginal device including a solid first segment that includes a hydrophilic semi-permeable elastomer, an outer surface and an aqueous lubricant, wherein the first segment is configured to deliver the aqueous lubricant to the outer surface.
