ABSTRACT:
Delivery devices which include a beneficial agent and an activating mechanism in separate compartments separated by a moveable partition are designed to deliver the beneficial agent in a pulsatile manner through an orifice. The pulsatile delivery is achieved by a band of resilient material which is placed over the orifice. The resilient material is sufficiently tight to substantially seal the orifice when the pressure within the device is below a threshold level while at the same time being capable of being stretched when the internal pressure exceeds the threshold.
