Method and device for endovascular treatment of the Alzheimer's disease

An endovascular method of treating a patient suffering from Alzheimer's disease comprising the steps of:

• conducting preoperative examination of the patient for detecting changes that occurred in the patient's brain in connection with Alzheimer's disease and for defining angioarchitechtonica of the arteries and capillaries in the affected zone of the brain;
• providing a microcatheter device comprising at least a first channel and a second channel, a plurality of microcatheters of gradually reducing diameters for coaxial insertion one into another through the first channel, a light-guiding optical-fiber device connected to a low-power laser source and insertable into the innermost of said at least three microcatheters, and a source of a cleaning liquid for the supply into the area being treated through the second channel;
• puncturing and catheterizing the common femoral artery of the patient for installing an introducer;
• inserting a first microcatheter of said plurality into the introducer;
• coaxially inserting and moving forward the second microcatheter of said plurality into the first microcatheters;
• coaxially inserting and moving forward the third microcatheter of said plurality into the second microcatheters;
• if necessary, sequentially inserting and moving forward other microcatheters of said plurality into the preceding microcatheter until reaching the affected zone of the microcirculation bloodstream in the patient's brain;
• inserting the light-guiding optical-fiber device coaxially into the innermost catheter of said plurality;
• guiding the light-guiding optical-fiber device to the affected zone through the innermost catheter;
• and
• restoring the circulation and collateral bloodstream in the brain with regeneration of the surrounding brain tissue by conducting laser treatment of the affected zone through a coronary blood vessel adjacent to the affected zone.
