Magnetic breather pump and a method for treating a brain tumor using the same
First Claim
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, andwherein 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.

Abstract
A magnetically controlled pump is implanted into the brain of a patient and delivers a plurality of medicating agents at a controlled rate corresponding to the specific needs of the patient. The current invention comprises a flexible double walled pouch that is formed from two layers of polymer. The pouch is alternately expanded and contracting by magnetic solenoid. When contracted, a medicating agent is pushed out of the pouch through a plurality of needles. When the pouch is expanded, surrounding cerebral fluid is drawn into the space between the double walls of the pouch from which it is drawn through a catheter to an analyzer. Cerebral fluid drawn from the patient is analyzed. The operation of the apparatus and hence the treatment is remotely controlled based on these measurements and displayed through an external controller.
