Abstract
The invention concerns a medical device for implantation in a body, comprising a stimulation unit, a sleep detector unit having at least one signal input which is adapted to detect a sleep condition of the body and to produce a sleep signal, an apnea detector unit which is adapted to detect sleep apnea in dependence on at least one body signal caused by the body and to produce an apnea signal, a therapy unit which is at least indirectly connected to the stimulation unit! the sleep detector unit and to the apnea detector unit and which is adapted to produce, in dependence on the apnea signal and the sleep signal, at least one apnea therapy signal which represents therapy information for preventing and/or for the treatment of sleep apnea, and to send same to the stimulation unit. The medical device has a position sensor, which is operatively connected to the signal input of the sleep detector unit and adapted in dependence on its inclination about at least one spatial axis extending through the position sensor in relation to the horizontal to alter at least one of its electrical properties.
