A regular metallic, cylindrical tubular needle cannula () is subjected to a metal etching liquid () in the inside lumen () thereby increasing the inside diameter and enhancing the flow properties while maintaining the outside appearance. The inside diameter is only increased over a controlled length () of the full length of the needle cannula () leaving sufficient length and wall thickness to also taper the outside diameter.

Method for chemical etching of a needle cannula

A needle magazine for holding a plurality of injection needles () is described. The needle magazine comprises a first opening adapted to receive the device fluid access portion () of a medical delivery device. Each needle () is selectively moveable from a respective storage position not aligned with said first opening into a needle mounting position aligned with said first opening. The needle magazine further comprises needle positioning means (). configured to alter the mutual position between a needle selected from said plurality of needles () relative to a neighbor needle when said selected needle moves from its storage position to the needle mounting position.
