Methods and devices for providing a gas pathway between the nasopharynx and the Eustachian tube are provided. Each imaging pixel may include floating diffusion metal lines associated with a floating diffusion node in that imaging pixel, pixel output metal lines associated with a pixel output, and additional metal lines. The means for effecting fluid flow cooperates with the fluid-transporting features to merge fluids from the fluid-transporting features in a manner effective to produce an output stream from the common outlet that exhibits at least one desired characteristic generated as a result of the differing dwell times. The bottle body has an opening and ribs. The method and arrangement afford a tie bar function.
