A method for employing a pre-assembled drainage catheter assembly for the insertion of a drainage catheter percutaneously. The assembly includes a trocar, a cannula, a catheter stiffener, and a catheter. The drainage catheter assembly is operated between a pre-assembled condition, a first step condition and a second step condition. In the first step insertion the trocar and cannula are inserted into a patient's body for obtaining a specimen fluid before the catheter is inserted. In the second step the catheter is inserted for collecting fluid. |
