Abstract
A method and assembly is provided which allows measurement of intracranial fluid characteristics at the intracranial region of the brain. The invention contemplates a method of implanting a ventricular catheter having one end residing in the ventricular region and the other end exiting the cranial region at a distal location. A grooved needle allows placement of a transducer tipped catheter and rerouting of both the ventricular, in-dwelling catheter and the transducer tipped catheter placed within the in-dwelling catheter. Intracranial fluid characteristics are monitored by an electrically coupled distal monitor. Further, access to the intracranial fluid is also provided to allow either short-term or long-term withdrawal or injection of intracranial fluid.
