The biopsy needle production is made 100% internally starting from the importation of the steel, titanium and nitinol from the most important supplier world wide. after that the tube and wire start to become needle by, the cutting and sharpting operation. A very sofisticate electro polish system has been implemented to offer the best smooth surface on the metal part, and guarantee a soft penetration. Years of research and experiance on the sharping give us the possibility to develop new geometry of sharping that guarantee the maximum petetration with the minimum pain. Accurate microscope assembling ends the "opera".
