FREDDY® Technology Now Available for Bile Duct Stones

FREDDY® Technology Now Available for Bile Duct Stones


Successful Laser Treatment Now Available for Bile Duct Stones
FREDDY® technology is effective, safe, cost-efficient and very gentle on patients

(Berlin, November 20, 2001) Between 8 and 10 million people in Germany suffer from gall stones. The risk of getting gall stones increases as we get older and women are more at risk than men. The main causes of gall stones are the consumption of fatty foods, obesity and repeated periods of strict fasting. Many people do not even know that they have gall stones. However, medical assistance is necessary when they cause acute pains in the upper stomach. These pains are usually accompanied by nausea and vomiting as well as a jaundiced appearance. In cases such as these, operating is generally the only answer.

To date, it has proven difficult to remove stones located in the bile duct. This situation, however, is now a thing of the past because W.O.M. WORLD OF MEDICINE AG’s FREDDY® technology offers a new patented efficient, safe and gentle method of treating patients with bile duct stones. The FREDDY® technology is a new laser procedure that was developed especially for the treatment of stones. This method is already being used successfully for the removal of stones in the ureter, bladder and kidney.

When treating bile duct stones, a quartz glass fiber is pushed through the gullet, stomach and duodenum with the help of an endoscope right up to the stone. The quartz glass fiber transfers the laser impulses. The Laser U100 is capable of disintegrating even the hardest stones in a very short period of time. The resulting fragments are small enough to be removed with a little basket, a small forceps or can be washed out. The FREDDY® technology is highly targeted and safe. Unlike other medical lasers such as those used in plastic surgery the Laser U100 can neither perforate nor burn soft body tissue. This means that it is virtually impossible to damage surrounding tissue, thereby generally rendering follow-up treatment superfluous.

Initial studies conducted at the University of Erlangen-Nuremberg show that significantly better treatment results can be achieved with the Laser U100 than with other methods of treatment even for complex bile duct stone removal. These stones can usually be removed using FREDDY® technology in only one treatment session. This accelerates the patients’ recovery and minimizes pain, allowing them to leave the hospital only a few days after receiving treatment. In this regard, the cost benefits of this procedure are considerable: short hospital stays help reduce health service costs.

W.O.M. WORLD OF MEDICINE AG has been listed on the Neuer Markt at the Frankfurt Stock Exchange since June 13 2001 and is considered one of the pioneers in the field of minimally invasive surgery. The group employs over 280 people at its locations in Berlin, Ludwigsstadt (Upper Franconia), Gröbenzell (Munich), Orlando (USA) and New Delhi (India). WORLD OF MEDICINE develops, produces and sells a range of products that has been developed especially for minimally invasive surgery. It is divided up into three corporate units:

The pump systems and insufflators produced by Flow&FluidWORLD® prepare for endoscopic treatment by carefully inflating body cavities with liquids and gases.
These gentle procedures are visualized and documented using VisionWORLD light sources, monitors, cameras and video documentation systems. LaserWORLD opens up new applications for laser-supported minimally invasive treatment with its innovative technology. The main focus here is on the new, highly efficient and patient-friendly FREDDY® technology for laser shock wave lithotripsy.
