Vivonics, in collaboration with physician researchers from Vanderbilt University Medical Center, developed a pulmonary artery flow restrictor system, covered by US Patent 10,568,634, for use in treating congenital heart disease. The device is designed to be deployed and adjusted minimally invasively via a percutaneous catheter by a cardiac surgeon, potentially avoiding an invasive surgical procedure. This technology has been licensed, through Vanderbilt University, to Influent Medical, LLC of Tennessee, which is further developing and commercializing the device.
