First paragraph (this article has no abstract)

The new proGAV represents the combination of a new adjustable differential-pressure unit including a "brake" in series with a gravitational device. By its construction principle the proGAV should be capable to avoid the main disadvantages of other so-called „programmable" valves: The burden of the necessity for repeated X-ray-controls, the sensitivity to irregular adjustments in MR and the ongoing danger to over drain of adjustable differential-pressure-valves.
