1. A respiration promoting apparatus to coordinatedly stimulate a first Phrenic nerve and a second Phrenic nerve of a patient for activating a diaphragm of the patient, comprising:
a first coil unit configured to be positioned at a neck of the patient only on an area above the first Phrenic nerve of the patient to stimulate a first Phrenic nerve of the patient;
a second coil unit configured to be positioned at the neck of the patient only on an area above the second Phrenic nerve of the patient to stimulate a second Phrenic nerve of the patient; and
a control unit configured to coordinatedly providing current to the first coil unit and to the second coil unit,
wherein each of the first and second coil units is associated with only one of the first and second Phrenic nerves,
wherein the first coil unit has a non-flat first coil winding formed from a conductive elongate component,
wherein the second coil unit has a non-flat second coil winding formed from a conductive elongate component,
wherein the control unit comprises a power supply coupled to the first coil winding of the first coil unit and to the second coil winding of the second coil unit, wherein the control unit is configured such that the power supply provides current through the first coil winding in a circulation direction and through the second coil winding in the same circulation direction,
wherein the first coil unit has a first housing encasing the first coil winding and the second coil unit has a second housing encasing the second coil winding, and
wherein the first and the second housing with the first and the second coil winding are configured to position and orient the first and second coil windings relative to the patient and relative to each other.
