A Fourier transform architecture and system for FFT and IFFT processing within multicarrier transceiver is disclosed that includes a programmable butterfly component, a memory and a programmable address generation unit. The stent body may include structural members defining openings through the stent body. The terminal electrodes connected to each lead is arranged at the side faces of the capacitor body. The second segment may be coupled to at least a portion of an exterior surface of the first segment and may have at least one cross-section dimension which is greater than an internal cross-sectional dimension of a delivery lumen.
