Abstract
An implantable medication delivery apparatus including a flow path coupling a medication reservoir to a device outlet port where the flow path includes a regulator means for limiting the magnitude of pressure transferred downstream from the medication reservoir. The regulator means is configured to respond to the reservoir pressure exceeding a certain threshold for closing a valve located downstream from the reservoir. The valve closure functions to isolate the device outlet port from further reservoir pressure increases which otherwise could induce unintended medication flow from the device outlet port.
