Dear Victor,
anything 22G is useless.
I managed to find at home just one PERICAN (epidural needle with Tuohy
needle) from BRAUN MENSUNGEN , that is made also by Braun Mensungen
factory in Malaysia. It is 18G x 3 1/4" (or 1.3 x 80mm), commonly used by
anesthesiologists.
At least your people will see what is the best needle for subaponeurotic
(for you) and intrathecal cell transplantation
