TWO-PIECE, INTERNAL-CHANNEL OSMOTIC DELIVERY SYSTEM FLOW MODULATOR.

摘要

An osmotic delivery system flow modulator includes an outer shell constructed and arranged for positioning in an opening of a reservoir of an osmotic delivery system, an inner core inserted in the outer shell, and a fluid channel having a spiral shape defined between the outer shell and the inner core. The fluid channel is adapted for delivery of an active agent formulation from the reservoir of the osmotic delivery system.
