Speed - Safety - Stonefree Highly Efficient and Safe to Use in Urology, Gynaecology and Gastroenterology The FREDDY 400 plus lithotripsy laser is the new standard for effective, safe and fast stone therapy. Using specialised, state of the art technology, this device guarantees tissue-protective treatment of even the hardest bladder, kidney or bile duct stones, in a faster and more cost-effective way than any other stone therapy currently available. The innovative Antiperforation Mode avoids the coagulation or perforation of surrounding tissue. In contrast to traditional laser lithotripters, for example based on Ho:YAG lasers, FREDDY 400 plus only affects solid material. This extraordinary safety feature results in shorter treatment and recovery times for the patient, as virtually no collateral damage can occur. The energy of the FREDDY 400 plus is transmitted by highly flexible fibre probes, fragmenting stones by a sequence of shockwaves. The extraordinary Dual Pulse of the device (see diagram) consists of a major infrared pulse with wavelength of 1.064 nm, along with a 532 nm green energy pulse which is highly absorbed by the stone material. During treatment, a high energy plasma beam is created between the fibre tip and the stone, which is converted into a mechanical shockwave during contact with solid stone material. This effect is athermal and therefore guarantees the protection of soft tissue even on direct contact with the fibre probe.
