Patent ID: 7799012

Claim:
A method for treating a brain tumor in a patient comprising: surgically implanting a cranium pump beneath the skull and dura of the patient's brain into a treatment site; coupling the cranium pump to an analyzer unit disposed outside the patient's brain via a fluid exchange catheter; operating the cranium pump within the brain of the patient in order to dispense a medicating agent to the treatment site under control of the analyzer unit; suctioning in a sample of cerebral fluid from the treatment site and transferring it to the analyzer unit; tracking and monitoring the progress of the patient's treatment via the analyzer unit; altering and changing the patient's treatment proactively by controlling the analyzer unit via an external controller communicated to the analyzer unit by an RF link, the external controller allowing proactive alteration of a delivery schedule of medicating agents to the brain of the patient by the cranium delivery pump based on measurements of a plurality of tumor parameters obtained from the cranium delivery pump and quantified by the analyzer unit; displaying the tumor parameter measurements on a display coupled to the external controller; and refilling and replacing a reservoir of medicating agent located in the analyzer unit, wherein suctioning the sample of the patient's cerebral fluid further comprises suctioning the sample cerebral fluid at a variable rate into an intra-membrane reservoir defined between an outer and inner membrane in the cranium pump by the oscillation of a magnetic solenoid and a plurality of pores defined within the surface of the outer membrane and around each distal tip of a plurality of hollow needles coupled to the inner membrane.
