Methods and related liquid crystal display devices are disclosed that reduceavoid a tearing effect in displayed images. Embodiments include an outer catheter assembly common to any mode of usage having a guide catheter having a lumen through which a guidewire and the greater portion of a hypo-tube carrying a flow director are passed and advanced. A pricing method suspends trading for a period of time if a price difference between two bids or offers by the same trader is too great. Another embodiment deflects the dispensing end from the main axis of the tube body, to facilitate targeted introduction of flowable material, even when the access path does not align the tube body along the natural geometric axes of the treatment site. The second tab is designed not to interfere with the first band end portion while expanding the band. The method further includes substituting each of the plurality of data regions with at least one OFDM symbol having variable duration, in which each of the at least one OFDM symbol has a cyclic prefix extension.
