A shunt 102 including an implantable housing having a proximal end and a distal end. A pressure sensitive valve 214 is contained within the housing at a position between the proximal end and the distal end, and capable of controlling a flow of fluid between the fluid inlet port and the fluid outlet port. The shunt further including a sensor assembly 216 fluidly coupled to the pressure sensitive valve, wherein the sensor assembly is mechanically actuated and capable of detecting the flow of fluid through the pressure sensitive valve. A condition of the shunt can be detected by detecting a flow of fluid through the shunt and generating a signal indicative of a period of fluid flow through the implantable shunt based on the detecting. The signal can be output to an external device capable of determining, from the signal, whether the shunt is malfunctioning. |
