1. A sustained release drug delivery system comprising:
- a drug reservoir comprising a therapeutically effective amount of an agent;
an inner tube having first and second open ends and covering at least a portion of said drug reservoir, wherein said inner tube is impermeable to the passage of the agent, dimensionally stable and capable of supporting its own weight; and
an outer layer, permeable to the passage of said agent, covering only a portion of said inner tube,wherein, upon implantation, agent is released through at least one of the open ends.

Abstract
A method and device for treating a mammalian organism to obtain a desired local or systemic physiological or pharmacological effect is provided. The method includes administering a sustained release drug delivery system to a mammalian organism in need of such treatment at an area wherein release of an effective agent is desired and allowing the effective agent to pass through the device in a controlled manner. The device includes an inner core or reservoir including the effective agent, an impermeable tube which encloses portions of the reservoir, and a permeable member at an end of the tube.
