Latest Patents

Among Hammerman's latest patents are groundbreaking inventions that address critical challenges in organ transplantation. His first significant patent is focused on the "Inducement of organogenetic tolerance for pancreatic xenotransplant." This approach establishes organogenetic tolerance through the transplantation of pig embryonic pancreas, allowing for subsequent implantation of porcine islets without the need for immune suppression. In this method, porcine pancreatic primordia are implanted into a mammalian subject, inducing tolerance before porcine islet cells are introduced.

Another notable invention is the "Chimeric pancreas," which presents innovative methods for increasing the pancreatic mass of a mammalian recipient. This process involves harvesting immature pancreatic tissue from a donor and implanting it into the peritoneal cavity of a recipient to develop a functioning chimeric pancreas that can produce insulin. This invention not only outlines methods for immunosuppression but also aims to enhance the vascularization and maturity of the transplanted tissue.
