A liquid crystal cell is presented that utilizes a deposited metal gasket moisture barrier and support membrane bonding two opposing plates of glass, a thin film spacer layer to accurately control cell gap thickness, and an optional integrated thermal sensor and heater deposition layer sandwiched therebetween. In order to avoid the problems inherent in extracorporeal ultrafiltration methods, the present invention removes fluid using an intravascular or intracorporeal dual-lumen catheter. The electrode is energized to contract the muscle and alter the airway passage. In response, the laser source may adjust the slope of the emitted beam accordingly.
