OncoSil Medical (formerly NeuroDiscovery) is a medical device company focused on localized treatments for patients with pancreatic and liver cancer. It offers OncoSil System, a brachytherapy device that implants a pre-determined dose of beta radiation via injection under endoscopic ultrasound (EUS) guidance. The beta particles emitted by OncoSil travel a short distance in the tissue causing damage to targeted cell DNA, which renders them incapable of further cell division and proliferation.
