The present invention relates to a device for administration to the mammary gland cavity of a subject including at least one active agent; and, at least one carrier material; and, characterized in that the environment into which the device is inserted into activates dispersion of the active agent. In further embodiments, a muco-adhesive material is used as a retainer material for the carrier material/active agent mixture.
