  • Osmotic delivery system, osmotic delivery system semipermeable body assembly, and method for controlling delivery rate of beneficial agents from osmotic delivery systems
    Patent number: 6923800
    Abstract: Osmotic delivery system semipermeable body assemblies that control the delivery rate of a beneficial agent from an osmotic delivery system incorporating one of the semipermeable body assemblies are provided. A semipermeable body assembly or plug includes a semipermeable body which is positionable in an opening of an osmotic delivery system. The semipermeable body has a hollow interior portion having a size selected to obtain a predetermined liquid permeation rate through the semipermeable body. Because the beneficial agent in the osmotic delivery system is delivered at substantially the same rate, the osmotic agent imbibes liquid which has permeated through the plug from a surrounding environment, and the liquid permeation rate through the plug controls the delivery rate of the beneficial agent from the osmotic delivery system.
