Natus Medical designs and manufactures audiological and neurological diagnostic and screening products. While the company's focus has historically been on infants (newborn hearing screening, neonatal monitoring), it has expanded its product line to include an array of screening and diagnostic systems for use with children and adults. Its systems detect such neurological conditions as epilepsy and balance and sleep disorders. Natus also manufactures newborn and infant care products to diagnose and treat brain injury and jaundice. The company sells its wares in more than 100 countries through a direct sales force and distributors.
