The development of the Dornier lithotripter progressed through several prototypes, ultimately culminating in February 1980 with the first treatment of a human by shockwave lithotripsy (SWL). The production and distribution of the Dornier HM3 lithotripter began in late 1983, and SWL was approved by the U.S. Food and Drug Administration in 1984. [26]
The medtech division was sold to an investment company and now bears the name Dornier MedTech. Dornier Medtech manufactures medical equipment, such as the Dornier S lithotripter, HM3, Compact Delta to treat kidney stones. Dornier MedTech also manufactures laser devices for a wide range of applications. [3]
ESWL was first used on kidney stones in 1980. It is also applied to gallstones and pancreatic stones. External shockwaves are focused and pulverize the stone which is located by imaging. The first shockwave lithotriptor approved for human use was the Dornier HM3 (human model 3) derived from a device used for testing aerospace parts.
Laser lithotripsy (LL) has been evaluated against Extracorporeal Shock Wave lithotripsy (ESWL), finding both to be safe and effective. [3] [4] ESWL may be safer for small stones (<10 mm), but less effective for 10–20 mm stones. [3]
Electrohydraulic Lithotripsy (EHL) is a medical procedure which uses targeted shockwaves to break up kidney stones and gallstones. [1] This form of extracorporeal lithotripsy is unique in that the shockwaves are produced by a vaporization bubble expanding and collapsing repeatedly, creating a pressure wave. [1]
Dornier designs were delivered to the Pomorsko Vazduhoplovstvo (Naval Aviation - PV) in 1926, namely the Dornier Komet and Dornier Do Y heavy bombers. The Yugoslavs were familiar with Dornier designs, and on 19 November 1935 Yugoslav pilots test-flew the Do 17 V-3 prototype, D-ABIH, W.Nr. 258. They decided to select the Do 17 for service ...
An email Dornier’s campaign shared with the Statesman showed that the county clerk’s office forwarded the campaign’s second complaint to the Secretary of State’s Office “for review ...
Claude Dornier was always trying to minimize the dependency of his company Dornier Flugzeugwerke on building aircraft, by diversification into other areas. After World War II , and the Allied ban on aircraft production in Germany until the late 1950s, Claude diversified the company's production and encouraged his son Claudius to find new areas.
