1. A method for measuring ventricular pressure, comprising:

  • positioning a distal end of a ventricular catheter within a patient'"'"'s ventricle;

    coupling a proximal end of the ventricular catheter to a valve inlet formed on an implantable valve having a valve assembly and a pressure sensor disposed therein, and coupling a valve outlet formed on the valve to a drainage catheter such that fluid flows from the ventricle through the implantable valve to the drainage catheter, wherein a rate of fluid flowing through the valve is controlled by the valve assembly disposed within the implantable valve; and

    obtaining a pressure measurement of the fluid flowing through the valve using the pressure sensor disposed within the valve, wherein the pressure sensor is located upstream of the valve assembly within the valve and thus the pressure measurement is made prior to the fluid flowing into the valve assembly.
