The phrenic nerve controls the diaphragm, which is the main muscle used for breathing. The electrode is connected to a receiver that is usually placed in the chest wall. An external transmitter then ...

An external transmitter then sends radiofrequency signals to the receiver, causing the electrode to stimulate (pacing) the phrenic nerve. The pacing makes the diaphragm contract. The aim is to help ...

Instead of trying to make an air-tight piston, he added a rubber membrane and a clever valve system to create a diaphragm air engine. This GIF is worth 115 words A round rubber diaphragm with a ...

Diaphragm valves get their name from a flexible disc which comes into contact with a seat at the top of the valve body to form a seal. A diaphragm is a flexible, pressure responsive element that ...

Now that at least four manufacturers have produced a complete MRI-conditional pacing system, with various types of leads available (tined, screw-in, etc.), either of these two problems do not ...

Diaphragm pumps are positive displacement pump which move gases, liquids, or gas-liquid mixtures via a reciprocating diaphragm. They are highly reliable because they do not include internal parts that ...

Respiratory failure usually causes death in MND patients within 2-3 years of symptom onset. Diaphragm pacing involves surgically placed electrodes that stimulate diaphragm muscle contraction in place ...

A diaphragmatic hernia (DH) is an opening in your diaphragm, the muscular sheet that separates your thoracic (chest) cavity from your abdomen. It's often a congenital condition (birth defect), but ...
