A catheter for administering medication into the endolymphatic sacs of the cochlea of the inner ear in humans, through at least one membrane of the inner ear. The catheter is designed with at least one outflow aperture at one end for the medication being administered and with an anchoring element. A medication dosage system can be connected to the other end of the catheter. The outflow aperture can be fed through the membrane of the inner ear and the anchoring element is designed so that it can anchor itself against this membrane.
