A debulking catheter comprising a tissue debulking assembly for removing a contiguous strand of material from a body lumen. An LCD device has the common and pixel electrodes on the same substrate and may be formed of a transparent conductive material to increase the brightness further. In addition, provided is a thin film transistor, including: a gate substrate; a metal oxide semiconductor manufactured to be overlapped with the gate substrate; a source electrode electrically connected to the metal oxide semiconductor; and a drain electrode that is electrically connected to the metal oxide semiconductor and faces the source electrode. Once actuated, the barrier or diverter either stops or diverts any dropped objects prior to the dropped object reaching and potentially damaging the valve member. An additional protuberance going through the inlay is protecting against luxation of the adjacent sliding.
