Insulin-dependent diabetics may opt for an insulin pump rather than injections. A pump provides much tighter control of the disease, more flexible eating habits, and lower risk of complications. Insulin pumps rely on disposable infusion sets to deliver insulin to the body. Inserting a set means driving its soft, hollow plastic cannula into the skin with a needle that is then withdrawn; the cannula is affixed to the skin with an adhesive patch and connected via tubing to the pump. Given the development cost (and risk) of designing and producing their own infusion set, Smiths challenged Bridge to help them create a product with significant user benefits over existing designs.
