titleOfInvention |
Osmotic delivery system having space efficient piston |
abstract |
An osmotic delivery system having a space efficient piston. The enclosure has an interior holding the piston, a beneficial agent, and an osmotic agent including a tablet. The piston is movable with respect to an interior surface of the capsule, and defines a movable seal with the interior surface of the capsule. The moveable seal separates the osmotic agent from the beneficial agent. The piston has a recess that receives at least a portion of the osmotic agent. The osmotic agent imbibes liquid from a surrounding environment through a semipermeable body to cause the piston to move and in turn cause delivery of the beneficial agent from the capsule. |
