Abstract:
1. A method of treating a subject having a neurological disorder by targeting a hippocampus in a brain, comprising the steps of: providing an outer tube; providing an inner tube; ensleeving said inner tube within a lumen of said outer tube, said inner tube extending distally from said lumen of said outer tube, said inner tube having an diameter along its length that is less than an internal diameter of said outer tube, such that said inner tube can be ensleeved within and extend distally from said lumen of said outer tube, said inner tube having a proximal end and a distal end, said distal end of said inner tube having an obtuse bend; providing a bendable, small gauge tube; ensleeving said bendable, small gauge tube within a lumen of said inner tube, said small gauge tube extending distally from said lumen of said inner tube at an angle resulting from said obtuse bend at said distal end of said inner tube, such that a distal end of said small gauge tube is external to said inner tube; said bendable, small gauge tube having an diameter along its length that is less than an internal diameter of said inner tube, such that said bendable, small gauge tube can be ensleeved within and extend distally from said lumen of said inner tube, manipulating said bendable, small gauge tube into a plurality of bends that are structured to permit said catheter to reach and deliver a substance to said hippocampus in said brain, said plurality of bends consisting of a first bend at an angle of about 150° and a second bend at an angle of about 90°, said second bend being distal to said first bend along an extent of said small gauge tube; coupling a pump tube to a proximal end of said outer tube; positioning a cap near the connection between said pump tube and said outer tube; and coupling an infusion or osmotic pump to said cap, such that said pump tube is positioned within a hollow interior of said infusion or osmotic pump, said hollow interior of said infusion or osmotic pump holding said substance to be delivered to said hippocampus in said brain, said substance being liquid based and selected from the group consisting of a compound, a biological, and a dye for treating said neurological disorder; and using more than one of said catheter on said brain of said subject, whereby a first of said substance may be delivered to a first region of the brain of the subject and a second of said substance may be delivered to a second region of the brain of the subject wherein said first substance does not mix with said second substance.
