Laparoscopic diaphragm pacing for tetraplegia.

(1) The NeuRx DPS is a laparoscopically implanted device that provides ventilatory support. (2) This device stimulates the diaphragm muscle, rather than the phrenic nerve, and is intended to lead to less risk of nerve damage than other therapies.(3) This technology provides an alternative to mechanical ventilation, and allows patients to increase day-to-day freedom and minimize the risk of respiratory infection. (4) The NeuRx DPS safety profile is based on clinical testing, which began with clinical trials starting in 2000. It has the potential to reduce costs, but this has not been well established.
