MICRO NEEDLE FOR TRANSPORTING FLUID ACROSS OR INTO A BIOLOGICAL BARRIER AND METHOD FOR PRODUCING SUCH A MICRO NEEDLE

摘要

The invention relates to a micro needle (1) for transporting fluid across or into a biological barrier. The micro needle comprises a shaft (2) having a hollow channel (3) ending in a tip (4) having a bevel at a predetermined angle. According to the invention the shaft is provided with an indentation (5) starting at the tip and running in longitudinal direction over a part of the outer surface having the shortest shaft length such that the channel has an unround cross section in the tip region. The invention further relates to a method for producing a micro needle according to the invention.
