Abstract: The present invention discloses a stent for supporting a sidewall of a lumen which contains a first fluid. The stent comprises a stent body, a film and a photosensitizing layer. The stent body is disposed inside the lumen. The film is adapted to be penetrated by a light and covers the stent body. The photosensitizing layer is disposed on an outer surface of the film for receiving the light to generate a first object, and the film separates the photosensitizing layer and the first fluid. The film and the photosensitizing layer of the present invention can greatly reduce the needed dosage of the photosensitizer while maintaining the effective concentration of the photosensitizer around tumor cells.

Abstract: Carbon dioxide contained within exhaust gas is combined with bivalent metal ions such as calcium ions or the like in concentrated salt water to form precipitated calcium carbonate and then can be expelled out. Such an environmental friendly design is realized by a bottle upside down device with a bottle neck exit on a bottom. A piston inside the device can be elevated to a top portion to produce a near vacuum air pressure inside the device. All the brine, exhaust gas, and oxygen, ozone drawn together into the device can be accelerated to form, at least, precipitated calcium carbonate to reduce carbon dioxide contained within the exhaust gas. Chemical reaction is accelerated by a high voltage discharger below the piston and by flashing a portion of water to atomize the brine. A heater can heat up the near vacuum device to accelerate chemical reaction.
