METHODS FOR TREATING ALZHEIMER'S DISEASE

Abstract

A method and system for treating Alzheimer's disease wherein blood, spinal fluid or brain cavity fluid is circulated into and outside of the body by means of blood pumps or other external circulatory systems. While passing through the pumping system, the amyloid plaques and Tao tangles are filtered from the fluids and returned to the body lowering the protein levels, and in the process, reduce symptoms. In one embodiment a patient's blood is filtered using a pump to circulate the blood from the patient to the collection vessel where an electrical current will cause anything that has a positive charge to be attracted to a cathode plate suspended in the collection vessel for later disposal. In an alternate embodiment a patient's brain and/or spinal fluid a pump operates to circulate a flushing fluid. The pump will circulate the solution from the collection vessel to the patient.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In the drawings which illustrate the best mode presently contemplated for carrying out the present disclosure:

[0015] FIG. 1 is a schematic illustration of a method and system for filtering and removing amyloid plaques and/or Tau tangles from the blood stream of a patient; and

[0016] FIG. 2 is a schematic illustration of a method and system for filtering and removing amyloid plaques and/or Tau tangles from the brain fluid and/or spinal fluid of a patient.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

[0017] Now referring to the drawings, FIGS. 1 and 2 illustrate generally a method and system for treating Alzheimer's disease and more particularly an electrochemical method of removing amyloid plaques and Tau tangles from the blood stream or from fluids circulating in and around brain tissues. As will be described in further detail below, in a first embodiment a patient's blood is filtered using a pump to circulate the blood from the patient to the collection vessel where an electrical current will cause anything that has a positive charge to be attracted to a negative cathode plate suspended in the collection vessel for later disposal. In an alternate embodiment a patient's brain and/or spinal fluid a pump operates to circulate a flushing fluid. The pump will circulate the solution from the collection vessel to the patient.

[0018] The present disclosure provides a means by which the body's natural electrochemical state can assist with an electrochemical deposition system for the removal of plaque from the brain, blood and spinal fluid. Amyloid Plaque and Tau Tangles are two protein molecules that are naturally occurring in the brain, blood and spinal fluid. It is reasonably certain that the accumulation of these proteins disrupts the part of the brain cells that channel the distribution of electrical signals. As noted above, there is ongoing research that suggests that removing these proteins may be a way of reducing Alzheimer's symptoms.

[0019] As generally known in electrochemical processes, current flow is from positive (anode) to negative (cathode). It is known that plaques and proteins are positively charged. The system of the present disclosure employs a negatively charged body (cathode) over which blood or other fluid containing the positively charged plaques or proteins are transported. As a result, the positively charged particles are electrochemically attracted to the cathode for removal to a cathode plate contained in a collection vessel.

[0020] Extracorporeal removal of pathogens or pathogen-related molecules is an upcoming scientifically investigated adjunct to the current palette of treatment options for known blood diseases and infections. Several membranes and filters with a specific binding profile are currently available for clinical use in available blood filtering systems.

[0021] In the present disclosure, blood, spinal fluid or a brain cavity flushing fluid may be circulated into and outside of the body (extracorporeally) by means of blood pumps or other external circulatory systems. While passing through the pumping system, the amyloid plaques and Tao tangles are filtered from the fluids and returned to the body lowering the protein levels, and in the process, reduce symptoms.

[0022] Turning now to FIG. 1, a first method and system is illustrated for the filtering of blood. A positive lead (anode) 12 extending from a low voltage/low current DC power source 14 positive lead (anode), is connected to the patient's body 16. A negative lead (cathode) 18 also extends from the low voltage/low current DC power source 14 and is connected to a metal plate 20 suspended from the center of a collection vessel 22.

[0023] Two ports are provided in the collection vessel, one port contains an IV tube 24 connected to the inlet for a pump 26. Another IV tube 28 is connected to an outlet of the pump 26 and then to the patient's vein 30. The other port contains an IV tube 32 connected to an artery 34. It should be appreciated that while two IV tubes 24, 28 are described many pumps 26 operate such that a continuous IV tube is directed through the pump body and as such the IV tubes 24, 28 may be a single continuous IV tube.

[0024] In some embodiments, a positron emission tomography dye (PET) Imaging Marker may be added to the patient's blood that binds to the plaques to be removed to facilitate the removal of plaque and imaging to confirm the plaque has been removed.

[0025] In operation, the pump 26 circulates blood from the patient 16 to the collection vessel 22. The current at the anode 18 plate 20 causes anything that has a positive charge (patient is the anode) to be attracted to the cathode plate 20 suspended in the collection vessel 22 for later disposal. Since the travel of direct current is from positive (anode) to negative (cathode), any debris (plaques, proteins, etc.) attached to the body organs not belonging there, will be electromagnetically attracted to the cathode 18 plate 20 suspended in the collection vessel 22.

[0026] Turning now to FIG. 2, an alternate method and system is illustrated for the filtering and or flushing of brain and/or spinal fluid.

[0027] A positive lead (anode) 12 extending from a low voltage/low current DC power source 14 positive lead (anode), is connected to the patient's body 16, preferably at the patient's head. A negative lead (cathode) 18 also extends from the low voltage/low current DC power source 14 and is connected to a metal plate 20 suspended from the center of a collection vessel 22.

[0028] Two ports are provided in the collection vessel, one port contains an IV tube 24 connected to the inlet for a pump 26. Another IV tube 28 is connected to an outlet of the pump 26 and then to a first hole drilled in the patient's skull to allow electrolytic flushing solution to enter. The other port contains an IV tube 32 connected to a second hole drilled in the patient's skull thereby allowing exit of the flushing fluid. It should be appreciated that while two IV tubes 24, 28 are described many pumps 26 operate such that a continuous IV tube is directed through the pump body and as such the IV tubes 24, 28 may be a single continuous IV tube.

[0029] In some embodiments, a positron emission tomography dye (PET) Imaging Marker may be added to the flushing fluid that binds to the plaques to be removed to facilitate the removal of plaque and imaging to confirm the plaque has been removed.

[0030] In operation, the pump 26 circulates electrolyte solution to the patient 16 to flush the plaques and proteins to the collection vessel 22. The current at the anode 18 plate 20 causes anything that has a positive charge (patient is the anode) to be attracted to the cathode plate 20 suspended in the collection vessel 22 for later disposal. Since the travel of direct current is from positive (anode) to negative (cathode), any debris (plaques, proteins, etc.) attached to the body organs not belonging there, will be electrochemically attracted to the cathode 18 plate 20 suspended in the collection vessel 22.

[0031] After this procedure is completed, a suction drain is employed to remove the electrolyte solution and the brain is flushed clear of liquid.

[0032] It can therefore be seen that the present disclosure provides an effective method of removing amyloid plaques and/or Tau tangles from the blood stream. Further, the present disclosure provides an electromechanical method of removing amyloid plaques and Tau tangles from the blood stream or from fluids circulating in and around brain tissues. For these reasons, the present disclosure is believed to represent a significant advancement in the art, which has substantial commercial merit.

[0033] While there is shown and described herein certain specific structure embodying the invention, it will be manifest to those skilled in the art that various modifications and rearrangements of the parts may be made without departing from the spirit and scope of the underlying inventive concept and that the same is not limited to the particular forms herein shown and described except insofar as indicated by the scope of the appended claims.
