About Us

ReSuture works to solve the most pressing needs in surgical education. The story of our company begins with an invention – a novel method to fabricate artificial human vasculature. Our founding team aimed to address the lack of training tools available to surgical residents, and founded ReSuture to bring our invention to residents and surgeons across the world. With a talented team of engineers and dedicated surgeons, we are committed to improving the quality of patient care.
