Abstract:
1. An apparatus for delivering medicating agents directly to the brain of a patient comprising; a magnetically operated cranium delivery pump disposable in the brain at a treatment site; a fluid exchange catheter coupled to the cranium delivery pump; a subdermally implantable chemotherapy pump device (CPD) coupled to the fluid exchange catheter; an external controller communicated to the CPD by means of an RF the external controller capable of altering 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 CPD; and a display coupled to the external controller, wherein the magnetically operated cranium delivery pump further comprises a head portion and a base portion and wherein an magnetic actuator is coupled to each said head and base portions of the pump, the surface of the head and base portions of the pump being coupled within each respective end of the magnetic actuator, wherein the magnetic actuator operates to alternate the cranium delivery pump between a contracted configuration and an expanded configuration to provide a pump cycle, and wherein the magnetic actuator further comprises an oscillating electromagnetic solenoid, an internal drug inlet fluidly coupled to a medicating agent reservoir, and an internal sampling fluid outlet fluidly coupled to a intra-membrane reservoir.
