Abstract
Surface micro-machined micro-needles () are formed as single needles () or in two-dimensional or three-dimensional micro-needle arrays (). The micro-needles () are fabricated on a substrate () which can remain attached to the micro-needles () or can be subsequently removed. The two-dimensional or three-dimensional micro-needle arrays () can have cross-coupling flow channels () which allow for pressure equalization, and balance of fluid flow within the micro-needle arrays (). Each of the micro-needles () has a micro-channel () therethrough that provides communication between at least one input port () at a proximal end of the micro-needles (), and at least on output port () at an opposite distal end.
