Abstract
In various aspects, systems and methods involve catheters having infusion sections with permeable membranes that develop significant back pressure to enhance uniform delivery of the drug over an infusion section; catheters that have two or more infusion sections spaced apart along the length of the same catheter, catheters that include two or more infusion sections serviced by independent lumens (such that, e.g., different drug solutions can be delivered to the different infusion sections); implantable drug delivery systems with pumps and multiple reservoirs from which drugs can be delivered; systems that are capable of delivering drug solutions with selected densities; etc. Methods for delivering a drug to a brain through a spinal canal include delivering hypobaric solutions containing the drug.
