A startup created to develop catheter-based technologies for replacing the mitral valve. Annulon has leveraged the large animal testing laboratory and the engineering/prototyping capabilities of Gorman-Gillespe Structural Heart (GGSH) to sequentially develop a sutureless mitral valve design, a minimally invasive off-pump mitral valve replacement technology, and a totally percutaneously placed mitral valve. An extensive patent portfolio has been created to protect the related intellectual property. Annulon is currently in discussion with several device companies regarding the development of a strategic partnership to bring these devices to clinical practice.
