Abstract
Devices and methods useful for sensing or measuring a pressure and remotely indicating or communicating that pressure are provided. The devices and methods have particular utility in sensing pressures in implantable medical devices and more particularly in hydrocephalus shunts. In one exemplary embodiment, an implantable valve can include a housing having a reservoir adapted to receive fluid flow therethrough between an inlet port and an outlet port. The implantable valve can also include a needle-penetrable septum to allow fluid delivery to the reservoir and/or a needle guard disposed within the housing and adapted to protect the radio frequency tag from a needle penetrating into the housing. A radio frequency (RF) tag can be disposed within the reservoir and can be adapted to change one or more of its electromagnetic characteristics in response pressure applied thereto by fluid in or flowing through the reservoir. The RF tag can produce a response to a wireless signal characterized by the one or more electromagnetic characteristics that correlates to a pressure of fluid in or flowing through the reservoir.
