ABSTRACT:
An implantable pressure-activated microvalve is disclosed. The valve includes a chamber that can be coupled to an external reservoir. A deflectable diaphragm is fluidically coupled to the chamber and arranged such that pressure of an in vivo fluid will bear against the deflectable diaphragm. When the pressure exceeds a selected threshold, the diaphragm deflects and allows material within the chamber to mix with the in vivo fluid.
