摘要:
The outer wall of a stiffenig cannula (2) is a discontinuous wall defined by the top of a plurality of projections (4b) extending from the cannula base wall in order to reduce the overall contact surface between the catheter (1) and the cannula (2) so making easy the drawing of the cannula from the catheter once the latter is in the operation location (Fig3).
