    • A delivery system is disclosed. The system is useful for the preprogrammed, unattended delivery of at least one beneficial agent to a pre-selected environment of use. The system comprises (I), a beneficial agent (II), a delivery module comprising, (a) a closed tubular member twined about itself to form a multiplicity of continuous, entwined, mated members, the members having, (b) an internal reservoir for storing agent in an amount for execution of the program, (c) a rate controller which maintains the rate of agent delivered in an effective amount from the members throughout the life of the system, (d) an energy source for transferring agent from the reservoir to the environment, and, (e) a portal for releasing agent from the members to the environment, (III), a platform which integrates the module into a unit sized, shaped and adapted for insertion and retention in the environment, and, (IV) a program which provides for the controlled release of agent to produce the desired beneficial effect over a prolonged period of time.
