Lung Assist II, Inc.

Lung Assist II, Inc. manufactures the Exsufflation Belt®, a wearable, non-invasive abdominal pressure device designed to provide daytime respiratory assistance for patients with ventilation-dependent conditions. The device addresses key limitations of traditional mechanical ventilation modalities—including tracheostomies, nasal masks, and phrenic nerve stimulators—by enabling patients to reduce work of breathing, achieve deeper inspiration, rest respiratory muscles, and restore upper extremity and oral mobility. The Exsufflation Belt is indicated for patients with neurological and neuromuscular disorders (spinal cord injury, muscular dystrophy, ALS), musculoskeletal disorders (kyphoscoliosis), and restrictive pulmonary disease. The device is simple, non-invasive, maintenance-free, and requires minimal training. Lung Assist II positions itself as a scientific research company reinventing and advancing a proven respiratory assist technology to improve quality of life for mechanically ventilated populations. The company is based in Boulder, Colorado.
