| titleOfInvention | Osmotic delivery device having a two-way valve and dynamically self-adjusting flow channel |
| abstract | An implantable, osmotically-driven delivery system having a dynamic, two-way valve (10) and self-adjusting, variable geometry fluid (1) flow channel. As pressure within the agent delivery system goes up, the fluid channel narrows , thereby restricting flow. At exceptionally high pressures, the valve can be designed to close altogether at the orifice or delivery end, or it can provi de a minimal leak path so that a maximum fluid flow is never exceeded. At zero or very low pressures, the valve will close completely at the beneficial agent reservoir end, isolating the beneficial agent formulation from external flui d infiltration and thereby eliminating diffusion of external fluid into the beneficial agent formulation. |
