Walz Lithotron EL 27 Compact TECHNOLOGIES FOR MEDICAL APPLICATIONS Large Stone Management Where other equipment is limited our Walz EHL helps The Technology: Micro-spark plasmas are produced between bipolar electrodes at the centre of the tip of the flexible probes by short high voltage pulses. The rapidly expanding and collapsing spark plasma bubbles generate micro shock waves with steep edges and minimized tensile phases in the surrounding liquid. Additionally, micro liquid jets with high velocity are produc­ ed which are directed at the stone. The Effects: These micro shock waves in...
