Diagphragm Pacing Technology

On June 24, 2002, LaszLo was injured and became a C3 tetraplegic. Implanted almost one year to the date of his accident, he was the fourth recipient of the diaphragm pacer for breathing assistance. Laszlo has been off the ventilator 24 hours a day, seven days per week ever since he received the system. He described it as ‘a true blessing’. The surgical procedure to implant the system is considered minimally invasive, and done on an outpatient basis. His surgery took about two hours. The diaphragm pacer consists of five hair thin wires; four that go from the chest down into the diaphragm with the fifth being an anode or ground wire. There are two electrodes attached at phrenic nerve motor points in each diaphragm. The wires are then tunneled through a connector on the chest going directly to the diaphragm pacer. It is a hardwired system. There is no transmitter. The electrodes contract and relax the diaphragm muscle used for breathing, independent of a typical ventilator system.
