TWO-PIECE, INTERNAL-CHANNEL OSMOTIC DELIVERY SYSTEM FLOW MODULATOR WITH SPIRAL FLUID CHANNEL

摘要

Disclosed is an osmotic delivery system flow modulator (200). The modulator includes an outer shell (202), an inner core (204), and a fluid channel (206). The outer shell is constructed and arranged for positioning in an opening of a reservoir of an osmotic delivery system, and includes an inner surface (212). The inner core is inserted in the outer shell, and includes an outer surface (210). The fluid channel has a spiral shape defined between the inner surface of the outer shell and the outer surface of the inner core, and is adapted for delivery of an active agent formulation from the reservoir of the osmotic delivery system.
