摘要

The catheter assembly has the catheter axis which possesses with the basic edge territory and the terminal territory and the time dynamic seal between both. This time dynamic seal has with the 1st part which is connected to the basic edge territory fixed and the 2nd part which is connected to the terminal territory fixed. As for the part, at overlap constitution it is made to engage. As for the time dynamic seal, it is made operation possible with invalid state and operating state. In invalid state, the 1st part and the 2nd part is divided by the air gap which is made time motion possible the terminal territory of the catheter axis vis-a-vis the terminal territory. In operating state, the 1st part and the 2nd part part, because of this the terminal territory that tries seals at least mutually engages stands still vis-a-vis the basic edge territory.
