  • Process for Shaping a Needle Cannula
    Publication number: 20140243761
    Abstract: A regular metallic, cylindrical tubular needle cannula (1) is subjected to a metal etching liquid (5) in the inside lumen (11) 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 (14) of the full length of the needle cannula (10) leaving sufficient length and wall thickness to also taper the outside diameter if so wanted.
