In connection with 'Katheter' (catheter), the verbs 'legen' (to insert/place), 'ziehen' (to remove), and 'tragen' or 'haben' (to wear/have, when it is inside the body) are often used.

'der Schlauch' and 'der Katheter' can both be a flexible, hollow part through which fluids flow. 'Schlauch' is the general word for everyday life, technology, or the garden, for example for water or air. 'Katheter' is a medical word. It is inserted into the body, for example to drain urine or administer medication. Learners may confuse the words because a catheter looks like a thin tube. In a hospital, however, you say 'Katheter', not simply 'Schlauch', when you mean the medical device.
Nach der Operation kontrolliert die Ärztin den Katheter.
After the operation, the doctor checks the catheter.
Im Garten ist der Schlauch geplatzt, deshalb läuft Wasser auf den Weg.
