The thoracic diaphragm, or simply the diaphragm, is a large flat muscle positioned within and across the bottom of the rib cage. Shaped like an open parachute, it separates the lungs from the stomach area. The diaphragm performs an important function in respiration. When it contracts, air is drawn into the lungs. Then, the muscle relaxes and air is expelled.
Diaphragm paralysis is the loss of control of one or both sides of the diaphragm. This causes a reduction in lung capacity. Patients with diaphragm paralysis may experience shortness of breath, headaches, blue lips and fingers, fatigue, insomnia, and overall breathing difficulty.
Causes of diaphragm paralysis include, but are not limited to:
- Direct trauma to the phrenic nerve (the nerve that controls the function of the diaphragm), either from surgery, radiation, or tumor
- Central neurological disorders such as a brain or brainstem stroke
- ALS (commonly known as Lou Gehrig’s Disease), multiple sclerosis, muscular dystrophy, or other neuromuscular diseases
- Spinal cord disorders and quadriplegia
Patients with a paralyzed diaphragm who have functioning phrenic nerves can seek treatment with the Avery Diaphragm Pacing System System.
The diaphragm pacing system uses surgically-implanted electrical impulses to rhythmically stimulate the phrenic nerve which helps restore breathing function. The surgery is performed by placing an electrode around the phrenic nerve, either in the neck or in the chest.
Patients with diaphragm paralysis who use the Avery Diaphragm Pacing System System may experience improved respiratory function and lower infection rates. Other benefits of the diaphragm pacing system include improved mobility, normalized breathing and speech patterns, and ease of eating and drinking.

The Avery Diaphragm Pacing System System
The Avery Diaphragm Pacing System System is the only diaphragm-pacing system with full pre-market approval from the USFDA and CE marking privileges under the European Active Implantable Medical Device Directive for both adult and pediatric use. In addition, its system of using small implanted radiofrequency receivers rather than electrode wires that pass directly through the skin may decrease a patient’s risk of infection and ongoing wound care management issues.
