Abstract
An embodiment of the invention is directed to a microfabricated, silicon-based, Convection Enhanced Delivery (CED) device. The device comprises a silicon shank portion, at least one individual parylene channel disposed along at least a part of an entire length of the shank, wherein the channel has one or more dimensioned fluid exit ports disposed at one or more respective locations of the channel and a fluid (drug) input opening. The fluid input opening may be configured or adapted to be connected to a fluid reservoir and/or a pump and/or a meter and/or a valve or other suitable control device(s) or apparatus that supplies and/or delivers fluid (eg, a drug) to the microfabricated device. The device may have multiple channels disposed side by side or in different surfaces of the device.
