Advanced Kidney Stone Treatment Lithotripter Arrives In Japan

Dornier MedTech Brings the Most Advanced Kidney Stone Treatment Lithotripter—Dornier Delta® III—to Japan


Dornier MedTech Delta III


Dornier MedTech, a global leader in innovative kidney stone management, has received PMDA (Pharmaceuticals and Medical Devices Agency) regulatory approval to market the Delta® III in Japan. This is the latest generation of the world’s best-selling and most clinically cited lithotripter, the Delta II.


The Delta III reflects Dornier’s continued commitment to develop the most cutting-edge solutions for kidney stone treatment. Compared to its predecessor, the Delta III provides improvements of:

  • Powerful IMAGING (for improved stone visualization)
  • Maximized ENERGY (to treat more stones in more patients)
  • Enhanced EFFICIENCY (with time saving efficiencies to serve more patients)


Powerful IMAGING:   the system provides improved imaging quality with 4 times1 more power and two imaging modalities (Ultrasound or X-ray) for better stone visibility.


Maximized ENERGY: Featuring Dornier’s exclusive Opticouple®, an optical camera system—visualized air bubbles are removed in the coupling gel at the interface of the therapy head and patient’s skin with a hand swipe.  Clinical research2 shows a 43% increase in effectiveness with less shock wave energy needed per treatment.


Enhanced EFFICIENCY:  Additionally, with OptiCouple, urologists can experience higher stone free rates3 and a 25% decrease in treatment time2, allowing doctors to see more patients per day to realize greater revenue.


Said Akira Kinoshita, GM, Dornier MedTech Japan, “About 1 in 10 people worldwide will have a kidney stone at some point in their lifetime, with more than 50% of patients experiencing one or more recurrences. The prevalence of stone diseases more than doubled in Japan during a 40 year period4, so our country’s launch of the popular Delta III lithotripter is a significant benefit not only for urologists but for kidney stone sufferers as well.”
