Nerve stimulation device
First Claim
1. A nerve stimulation device comprising:
- a pulse generator which generates stimulation pulses;
an electrode arrangement connected to the pulse generator configured to interact with a living subject to deliver the stimulation pulses to stimulate the phrenic nerve;
a cardiac signal detector configured to obtain an ECG signal from the living subject indicative of a degree of stimulation of the vagus nerve of the living subject associated with the stimulation of the phrenic nerve by said stimulation pulses; and
a regulating unit connected to said cardiac signal detector and to said pulse generator for regulating the pulse generator dependent on the ECG signal to reduce said degree of stimulation of the vagus nerve by said stimulation pulses.

Abstract
A nerve stimulation device has a pulse generator for generating stimulation pulses and an output for the stimulation pulses from the pulse generator, which is connectable to an electrode arrangement adapted for interaction with a living being to stimulate the phrenic nerve. The nerve stimulation device is made more safe and effective by the provision of an input connectable to an esophageal electrode for the reception of measurement signals. The esophageal electrode is adapted to be inserted in the esophagus of the living being for obtaining measurement signals. A signal analyzer filters myo-electrical signals from the diaphragm out of the measurement signals and a regulating unit regulates the pulse generator dependent on the myo-electrical signals.
