A system and method for automatically adjusting a Continuous Cycling Peritoneal Dialysis therapy to minimize the potential for excess intra-peritoneal volume. The delay time of the rising edge of the output voltage from the previous level shift unit is compensated by the delay time of the falling edge of the output voltage from the next level shift unit, and the delay time of the falling edge of the output voltage from the previous level shift unit is compensated by the delay time of the rising edge of the output voltage from the next level shift unit. A catheter for delivering the stent of the invention may include a balloon having a comparably flared shape and an inverse conical distal end. By maintaining information pertinent to prevailing wireless conditions, quality of service requirements, pilot signal reports, mobility management considerations, and so on, of transmissions within the cell, significant interference reduction can be implemented for the macro coverage area, or nearby coverage areas. Each rail defines two locking slots adjacent to opposite ends of the rail.
