Abstract

An intra-orifice medicament delivery system and formation method involve a housing defining an inner chamber extending along a longitudinal axis, with the chamber wall defining one or more openings therethrough. A retention arrangement extends from the housing, and is adapted to removably retain the housing within a bodily orifice defined by an orifice wall. An osmotic delivery device is disposed within the chamber and includes an osmogen portion and medicament-including portion disposed within a semipermeable membrane. The osmogen portion expands and applies pressure to the medicament-including portion in response to absorption of a liquid from within the bodily orifice permeating through the semipermeable membrane. The medicament-including portion is arranged to emit a medicament in response to the pressure applied by the expanded osmogen portion, with the medicament exiting through a membrane orifice defined by the semipermeable membrane and subsequently exiting the housing through the one or more openings such that the medicament is delivered into the bodily orifice.
