Abstract: A catheter system (100) for treating a treatment site (106) includes an energy source (124), a catheter fluid (132), and an emitter assembly (129). The emitter assembly (129) includes (i) at least a portion of an energy guide (122A) having a guide distal end (122D) that is positioned near the treatment site (106), (ii) a plasma generator (133), and (iii) an emitter housing (260) that is secured to the energy guide (122A) and the plasma generator (133). The emitter housing (260) includes (a) a first housing section (262) that is secured to the energy guide (122A) at or near the guide distal end (122D), (b) a second housing section (264) that is one of secured to and integrally formed with the plasma generator (133), and (c) a connector section (266) that is coupled to and extends between the first housing section (262) and the second housing section (264).

Abstract: An encoder implements a residual-free palette encoding mode in which a block of pixels is used to derive a palette table having a number of palette colors less than a number of pixel colors in the block of pixels, and to derive a color map representing each pixel of the block with a corresponding index number associated with a palette color that most closely matches the pixel's color. The calculations of residuals representing errors between the predicted palette colors and the actual pixel colors are omitted during the encoding process, thereby facilitating implementation of less complex palette mode encoder hardware at the expense of slight loss of color accuracy. Moreover, when multiple encoding modes are available, the encoder can employ the residual-free palette encoding mode when the rate-distortion cost or other cost of using this mode is determined to be the lowest cost of the plurality of encoding modes.
