A lithotriptor is a
medical device used in the
non-invasive treatment of
kidney stones (urinary calculosis) and
biliary calculi (stones in the
gallbladder or in the
liver). The scientific name of this procedure is Extracorporeal Shock Wave Lithotripsy (ESWL). Lithotripsy was developed in the early 1980s in Germany by Dornier Medizintechnik GmbH (now known as Dornier MedTech Systems GmbH), and came into widespread use with the introduction of the HM-3 lithotriptor in 1983. Within a few short years, ESWL revolutionized treatment of calculosis. It is estimated that more than one million patients are treated annually with ESWL in the USA alone.
