    摘要: Bei einem Verfahren zur Herstellung einer in Körpergewebe einstechbaren Mikronadel (12), bei welchem eine Nadelspitze (20) und ein vorzugsweise kapillarer Sammelkanal (14) für Köperflüssigkeit geformt wird, ist es vorgesehen, dass zumindest ein Teil eines aus einem Flachmaterial vorgefertigten Vorformlings (38) zu einer Rohrstruktur (22) umgeformt wird, so dass der Sammelkanal (14) im Bereich der Rohrstruktur (22) zumindest im Wesentlichen ringförmig geschlossen wird.

    摘要: A method is provided for forming a feature on a needle. In particular, a hollow, metal cannula (10) has a first end, a second end and a substantially constant outer diameter extending over at least a portion of its length. An annular metal sleeve (40) is provided that has a proximal shoulder and a distal shoulder. The length of the annular sleeve is less than the length of the constant diameter portion of the cannula. The sleeve has an inner diameter approximately equal to or less than the outer diameter of the constant diameter portion of the cannula. Two edges extend axially along the length of the sleeve, from the proximal shoulder to the distal shoulder, thereby defining a slit. The sleeve is positioned on the cannula at the constant outer diameter portion in an interference fit. An additional mechanical junction is provided to secure the sleeve to the cannula. For example, the sleeve may be welded to the cannula using a laser welder at at least one edge of the sleeve near one of either the proximal face or the distal face. Alternatively and additionally, the sleeve may be crimped or glued to the cannula. In accord with another aspect of this invention, a needle is provided made in accord with this method.
