Acclarent's medical technology helps people breathe easy without surgery. The company created the Balloon Sinuplasty, a minimally-invasive device used to treat patients with chronic sinusitis. The Balloon Sinuplasty opens blocked sinuses by inflating a balloon in the sinus cavity instead of cutting away bone and tissue, and patients can return to work as soon as the next day. The FDA-approved device is marketed directly to ear, nose, and throat (ENT) doctors in the US and internationally. Acclarent is a unit of medical equipment maker Ethicon, which is in turn a Johnson & Johnson subsidiary.
