Patent ID: 8323269

Claim:
A method for delivering medicating agent into the cerebrospinal fluid (CSF) in a patient comprising: surgically implanting a catheter into the CSF of the patient at a defined treatment site; coupling the distal end of the catheter to a magnetically operated spinal pump disposed at the treatment site; coupling the proximal end of the catheter to an analyzer unit disposed outside of the treatment site; operating the pump within the CSF of the patient in order to infuse medicating agent to the treatment site under control of the analyzer unit; suctioning in a sample of the CSF from the treatment site and transferring the CSF sample 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 comprising means for allowing proactive alteration of the delivery schedule of medicating agents to the treatment site of the patient by the spinal pump based on measurements of a plurality of parameters obtained from the spinal pump and quantified by the analyzer unit; displaying the 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 in the sample of the CSF further comprises suctioning the sample of the CSF at a variable rate into an intra-membrane reservoir defined between an outer and inner membrane in the spinal 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 inner membrane.
