Caption: This series of photos demonstrates how an innovative new catheter can be kept free of biofilms. When biofilm builds inside the catheter (denoted by the pink substance in the left image), pressure is forced through the neighboring channel (the dotted line in the left image and the expanded 'P' space in the central graphic) causing it to rapidly expand into the main shaft. The result is the dislodging of the biofilm, as evident in the final image.
