Is your company developing innovative new technologies targeting heart, lung, blood, or sleep (HLBS)-focused complications of pregnancy? If so, the National Heart, Lung, and Blood Institute (NHLBI) is now participating in the NOSI for  Small Business Initiatives for Innovative Diagnostic Technology for Improving Outcomes for Maternal Health (NOT-EB-21-001). The NHLBI is interested in projects focused on detecting, predicting, and/or monitoring HLBS disorders during pregnancy and/or the post-partum period, as well as projects that enhance the monitoring and management of women with existing HLBS-specific disorders and risk factors who enter pregnancy or are considering becoming pregnant.
