Abstract :
Diabetes mellitus is a chronic metabolic disorder characterized by persistent hyperglycaemia resulting from defects in insulin secretion, insulin action, or both. Effective glycemic control is essential to prevent long-term complications such as cardiovascular diseases, neuropathy, nephropathy, and retinopathy. Conventional insulin delivery methods, including multiple daily injections and external insulin pumps, have improved diabetes management; however, these approaches are often associated with limitations such as patient discomfort, inconsistent insulin absorption, risk of hypoglycemia, and poor treatment adherence. To overcome these limitations, implantable insulin delivery systems have emerged as an innovative approach for achieving more precise and physiological insulin administration. These devices provide continuous and controlled insulin release directly within the body and typically consist of an insulin reservoir, pumping mechanism, catheter, and programmable control unit. Recent technological advancements include implantable insulin pumps, closed-loop artificial pancreas systems, and bioartificial pancreas models integrating continuous glucose monitoring with automated insulin delivery. Additionally, emerging strategies involving nanotechnology, glucose-responsive biomaterials, and smart insulin formulations are being explored to enhance efficiency and safety. These advanced systems improve glycemic regulation, reduce injection burden, and enhance patient compliance. Despite promising benefits, challenges such as surgical risks, device malfunction, infection, high cost, and long-term biocompatibility concerns remain. Future developments focusing on miniaturization, automation, advanced sensing technologies, and stem cell-derived beta-cell implants may transform diabetes therapy. Overall, implantable insulin delivery systems represent a significant advancement toward achieving improved glycemic control and improving the quality of life for individuals living with diabetes.
