Caption: The yellow cast of an innovative new catheter design created by a 3D printer is shown on the left along with the finished prototype on the right. The markings indicate the urinary duct (U), the flexible inner wall (i.w.) between the urinary duct and the inflation channel (I) and the stiff exterior wall (e.w.). Pressurizing the narrow chamber deforms the main channel, dislodging biofilm so that it can be flushed from the tube.
