摘要： 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.

摘要： A cochlear implant of a cochlear implant system is described. The cochlear implant comprises electrodes which are mechanically connected to one another and can be inserted in a row in the form of a spiral into a cochlea in order for auditory nerve receptors to be stimulated, a control circuit that can specifically apply electric pulses to the individual electrodes, and an energy source. The control circuit allows the electrodes to be fed in a pulsed manner with electric signals generated by a processor from the acoustic signals, and auditory nerve receptors adjacent to the electrodes to be stimulated. The electrodes are components of modules, each of which comprises its own decoder-and-control circuit for decoding module addresses and stimulation signals and generating electric pulses for the electrodes. Encoded module addresses and stimulation signals generated from acoustic signals are applied to inputs of the decoder-and-control circuit.

摘要： The invention is related to a surgical device for patient-specific guidance of at least one tool used during a surgical intervention, comprising at least the following features: a) at least one carrier system which is arranged for fixation on a bone structure of a patient, b) at least one guiding system connectable to the carrier system, the at least one guiding system comprising at least one base module and at least one guiding part for precisely defined guidance of at least one tool used during the surgical intervention, c) at least one connecting means for establishing a mechanical connection between the at least one guiding part and the at least one base module, wherein the connecting means comprises at least a non-fixed operating state and a fixed operating state, wherein in the non-fixed operating state the at least one guiding part can be adjusted relative to the base module in a patient-specific adjustment and in the fixed operating state the at least one guiding part is mechanically fixated relative to the at least one base module in the patient-specific adjustment, d) at least one mechanical interface for connecting the carrier system to the guiding system, comprising first interface means of the carrier system and second interface means of the guiding system, wherein the first interface means can be connected via form fit with the second interface means, thereby ensuring a defined adjustment of the guiding system relative to the carrier system by means of form fit. The invention is further related to a method for preparation of such a surgical guidance device.

摘要： The invention relates to an irradiation device and a corresponding method for irradiating a radiation absorbing medium, as well as a hearing aid device and a laser surgery device comprising such an irradiation device. A radiation source is configured to generate one or more pulses of electromagnetic radiation and to irradiate the medium with the one or more pulses of electromagnetic radiation. A control unit is configured to control the radiation source such that the time course of the power or intensity of at least one pulse of the one or more pulses of electromagnetic radiation exhibits a rising slope and/or a falling slope, wherein the rising slope and/or falling slope has a maximum gradient which is smaller than a predetermined gradient value, whereby a generation of optoacoustic waves in the medium in response to the rising slope or falling slope, respectively, is avoided or significantly reduced.
