Abstract
An access cannula which includes a dwell tube that serves as an access during treatment. A blocking device that maintains the dwell tube kinked in an idle position. In the idle position, the dwell tube is maintained kinked, preferably at a predetermined kink point that corresponds to a position in which a force exerted by the blocking device upon the dwell tube, the elastic reset force of the dwell tube and, where appropriate, a pressure prevailing in the dwell tube, balance one another.
