Apparatus for pancreatic function restoration using membrane with cell systems
A recently granted patent (Publication Number: US11918955B2) discloses an innovative apparatus designed to restore or supplement pancreatic function. The apparatus comprises a functional unit with a membrane separating two channel systems, one of which is populated with pancreatic islet cells to generate functional pancreatic tissue. The membrane is a biocompatible extracellular matrix membrane embedded into a matrix material, with specific characteristics such as a minimum shear stress and transmembrane pressure. The apparatus also includes biological fluid inflow and outflow conduits, vascular channel walls lined with endothelial cells, and can be configured with multiple functional units stacked in parallel layers.
Moreover, the patent details methods for treating patients with insufficient pancreatic function using the apparatus, either by implanting it in the patient or operating it extracorporeally. The manufacturing process involves creating membranes with sacrificial material for the channel systems, submerging them in a scaffold material solution, gelating the material, removing the sacrificial material to form luminal spaces, and populating the second channel system with pancreatic islet cells. This method can also include populating the first channel system with endothelial cells, further enhancing the functionality of the apparatus for pancreatic treatment. Overall, the patent presents a comprehensive approach to addressing pancreatic insufficiency through a sophisticated apparatus and method, offering potential benefits for patients in need of pancreatic function restoration or supplementation.
