MiRus

Marietta, Georgia, United States

MiRus LLC is a privately held medical-device and biomaterials company headquartered in Marietta, Georgia. Its own company profile reports founding in 2015 and launch in 2016. Led by interventional cardiologist Jay Yadav, it develops proprietary molybdenum-rhenium (MoRe) superalloys, implants and procedural systems for spinal, orthopedic and structural-heart disease. Its platform also includes surgical navigation and remote physiological monitoring. MiRus reports FDA 510(k) clearance of its first MoRe spine implant in 2019 and subsequent product-specific clearances, including the IO Expandable Wedge Osteotomy System announced in February 2026; this does not constitute approval of every product or disease indication. Its SIEGEL transcatheter aortic valve remains investigational and was not approved for commercial distribution in any country in the May 2026 announcement. The STAR randomized pivotal trial had begun enrolling patients in April 2026 under investigational authorization. In July 2021 the company completed a USD65 million growth financing led by Mammoth Scientific and unnamed multigenerational family offices. Boston Scientific announced a USD1.5 billion strategic payment in May 2026 for approximately 34% minority equity and an exclusive TAVR acquisition option; its SEC filing specifies 33.75% nonvoting equity and a prior USD100 million payment included in a total USD1.6 billion paid package, with equity versus option allocation undisclosed. The additional USD3 billion option-exercise payments are conditional future consideration, not funded capital. MiRus remains a distinct minority-held company; a full acquisition of its TAVR business has not been verified as completed.
