Vivos Inc. is a radiation oncology medical device company. The Company has developed an Yttrium-90-based injectable Precision Radionuclide Therapy medical device to treat tumors in animals (IsoPet) and humans (RadioGel). Using the Company’s proprietary hydrogel technology, PRnT uses highly localized radiation to destroy cancerous tumors by placing a radioactive isotope directly inside the treatment area. The injection delivers therapeutic radiation from within the tumor without the entrance skin dose and associated side effects of treatment that characterize external-beam radiation therapy. This feature allows the safe delivery of higher doses needed for treating non-resectable and radiation-resistant cancers. University veterinary hospitals use the IsoPet Solutions division to demonstrate animal cancers’ safety and therapeutic effectiveness. RadioGel is a hydrogel liquid containing tiny yttrium-90 phosphate microparticles that may be administered directly into a tumor.
