Summary for Patent: 6,113,938
Title: Beneficial agent delivery system with membrane plug and method for controlling delivery of beneficial agents
Abstract:An osmotic delivery system for controlled delivery of a beneficial agent includes an implant capsule containing a beneficial agent and an osmotic agent which swells on contact with water causing the release of the beneficial agent over time. The osmotic delivery system has a membrane plug which allows water to pass through the plug from an exterior of the capsule while preventing the compositions within the capsule from passing out of the capsule. A delivery rate for delivery of the beneficial agent from the implant capsule is controlled by varying a core diameter of the membrane plug within a constant diameter capsule. The membrane plug has a variable water permeation rate depending on an extent to which the membrane plug is constrained by the capsule walls.
