NOTE

  • In this subclass, the following term is used with the meaning indicated: In this subclass, the following term is used with the meaning indicated:
    • "therapy" implies that the treatment, when it aims at destroying sick or abnormal cells, is performed within the limits of healthy cell life, the destruction thereof being undesired, contrary to that which takes place with instruments, devices or methods covered by group A61B 18/00.
