This $250,000 National Science Foundation Engineering (47.041) Project Grant funds the development of a novel annuloplasty ring prototype for minimally invasive mitral valve repair. North Carolina State University will lead an interdisciplinary team to design, 3D print, and test ring structures using magnets for catheter-guided magnetic assembly within pig hearts and tissue phantoms. The compact ring design aims to enable percutaneous delivery and diameter reduction through catheters to improve leaflet coaptation and treat mitral valve regurgitation as an alternative to open-heart surgery. Duke University will oversee materials selection, 3D printing, mechanical testing, prototype design advising, and commercialization/entrepreneurship mentoring under a sub-award as part of the effort to translate the technology. The award period is from April 1, 2022 through March 31, 2024.
