ABSTRACT:
A cannula assembly especially for medical use is disclosed which virtually eliminates coring during the piercing of a barrier. The cannula assembly includes a hollow cylindrical shank and a piercing tip removably mounted in and closing one end of the shank. Pressurized introduction of fluid through the shank forces the piercing tip out of engagement with the shank, placing opposite sides of the barrier in fluid communication.
