Claim 4:
5. A method comprising:
supplying a drug for treatment of a disease to a body space via an implanted catheter and delivery system;
monitoring pressure of fluid in the body space with an implanted pressure sensor;
measuring at least one optical absorption profile of cerebrospinal fluid (CSF);
communicating the measured at least one optical absorption profile of the CSF to an external monitor; and
wirelessly communicating the monitored pressure of the fluid to the external monitor using an implanted wireless communication subsystem,
where supplying a drug for treatment of a disease to a body space via an implanted catheter and delivery system comprises supplying the drug through an implanted vascular access port (VAP) communicated to the implanted catheter and delivery system, and
where measuring at least one optical absorption profile of the CSF comprises introducing light from an LED bundle into an optical sensing chamber filled with the CSF and reflecting the introduced light back to a photodetector.
