Our team is passionate about transforming the lives of people who struggle with the current post-surgical drain options. After witnessing the experience of people who live with JP drains, we felt compelled to create a solution that has the potential to profoundly help people. With years of clinical interviews and engineering research, we decided to start SOMAVAC® Medical because we wanted to help patients now.
