AnelleO is a medical device company that is developing a 3D printed intravaginal ring that can be used as a platform for treating a wide range of women's health conditions. Their first product, AnelleO PRO involves the only single administration of progesterone for infertility. Their technology enables controlled drug-release kinetics with up to 100% drug release, as well as rapid manufacturing and custom sizing. The manufacturing method allows for formulation of biologics and drug combinations not possible with traditional technologies. AnelleO was founded by Rahima Benhabbour, professor at the Eshelman School of Pharmacy/UNC_NCSU Joint Biomedical Engineering Department, and Post Doctoral Fellow Rima Janusziewicz.
