The Avery Diaphragm Pacing System consists of surgically implanted receivers and electrodes and an external transmitter with antennas worn directly over the implanted receivers.

The external transmitter and antennas send radiofrequency energy to the implanted receivers just under the skin. The receivers then convert the radio waves into stimulating pulses.

These pulses are then sent down the electrodes to the phrenic nerves, causing the Diaphragms to contract. This contraction causes inhalation of air. When the pulses stop, the diaphragms relax and exhalation occurs. Repetition of this series of pulses produces a normal breathing pattern.
