Abstract
The invention provides exemplary devices and methods electrically stimulating the phrenic nerve. In one embodiment, electrodes are placed posterior and anterior in the region of the cervical vertebrae. Electrical current having a multi-phasic waveform is periodically applied to the electrodes to stimulate the phrenic nerve, thereby causing the diaphragm to contract.
