Synapse Biomedical is advancing into Canada with its device designed to help pace the diaphragm for spinal cord injury victims with breathing problems. The Cleveland company said it won Health Canada approval for its NeuRx diaphragm pacing system for ventilator-dependent spinal cord injury patients who can't control their diaphragms. NeuRx is implanted through laparoscopic surgery and electronically stimulates the diaphragm muscles to help it contract, mimicking natural breathing, and it helps patients avoid using a mechanical ventilator. The product gained a CE mark in 2007. In the U.S., it has had FDA approval since 2008. Item
