Abstract
System and method to improve drug delivery to identified regions in the brain or elsewhere through direct infusion of a therapeutic agent or the like into that region. This direct infusion will allow for greater concentrations of the agent in the target region while reducing concentrations elsewhere in the body where these agents may be toxic. The system and method improves efficacy while reducing unwanted side effects. The system includes an array of multiple, independently targeted, microporous catheters for insertion into the target region and a distribution system that allows for individualized flow control to each catheter. The system may be connected to a reservoir that contains the therapeutic agent, and flow to the system is maintained through one or more pumps. This system will greatly improve on the current single catheter infusion design and shall provide therapy, delivered through multiple catheters, thus delivering the therapy evenly over a customizable volume.
