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.

The invention relates to a marking of cartridges, carpules or any kind of package. The marking can be in an electronically readable form while being transparent. Hereby a marking with improved security for avoiding reading errors which ensures a mandatory visual inspection of content is obtained. The transparent conductor can be in form of a polymer, an ITO and the like. These transparent conductors are used in an improved marking technique, which further improves reading security. The invention may e.g. be used in connection with medication delivery devices for self-treatment of a disease, e.g. diabetes.

In a method of making a replication tool, replication parts for both two dimensional optical elements, such as are fabricated using micro-forming techniques, and three dimensional optical elements, that are typically formed using cutting techniques are present on the replication tool. A method of manufacturing a replication tool for a planar optical sheet includes mounting at least one optical element part on a base to form a master part and forming a conductive metal layer over the master part. The method also comprises electrochemically depositing over the conductive metal layer to form an electrochemically deposited layer, separating the electrochemically deposited layer from the master part. The invention also relates to the replication tool itself and optical circuits formed using the replication tool.
