Bilitz Design had its work cut out for it. Not only did it have to solve a particular problem with a delicate surgical procedure, but it had to develop a patentable device to distinguish its client from other competitors. Bilitz delivered on both counts with its injection-molded handle for the basket that is inserted through an endoscope to remove bile duct stones. This handle is lighter than any other on the market, which keeps it from kinking or bending the wire during transport. The designers also added a "spinner" which is a patentable feature that allows the surgeon to turn the basket inside the patient without having to turn the entire handle.
