PneumRx has developed a minimally invasive device to treat emphysema. Their innovative implantable deviceis designed to improve lung function in patients with emphysema by reducing lung volume. The PneumRx Coilsare implanted through a bronchoscope in a simple and short procedure, under conscious sedation or general anesthesia. Due to the limited efficacy of drug treatment for emphysema, this new technology addresses a high unmet medical need. PneumRX was acquired by BTG in December 2014.
