Abstract: A system includes a stent Including a first end for arrangement on a tubal ostium, a second end for arrangement on a bony isthmus of smaller diameter than a diameter of the first end, and adjacent to the second end a length portion of decreasing diameter. The system further includes an applicator for placement of the stent in a Eustachian tube. The applicator has a proximal end for handling the applicator and a distal end for receiving the stent. The distal end includes an inner part which has at least one area that is plastically deformable by manual force, for adaptation to a patient-dependent access angle of the Eustachian tube, and an outer tube which surrounds the inner part at a radial distance and which delimits an annular gap for receiving the stent, with the stent in the annular gap made of nitinol and being self-expanding.
