Highly Efficient and Safe to Use in Urology, Gynaecology ... - Liamed

Company Profile
Limmer Laser GmbH is a German company, specialising in the design,
manufacture and sale of medical lasers and accessories. Our products
cover all the major disciplines of human, dental and veterinary medicine.
For each discipline a broad range of high quality accessories is available,
such as the VACULAS smoke evacuator. The product range includes CO2
Lasers, Diode Lasers and Specialty Lasers.
Instead of simply focusing on separate devices, our philosophy is to create
multipurpose, integrated and highly functional work stations. Working
with our many loyal customers all over the world, and our established
network of suppliers and distributors, we will continue to provide
innovative solutions for modern medicine far into the future.
We have a strong emphasis on research and development, production,
service and training. Working in conjunction with hospitals and
physicians is just as important as good communication. Product quality is
our No. 1 priority: Our company is certified to the stringent European
Quality Standard EN ISO 13485:2003.

FREDDY 400 plus
Speed - Safety - Stonefree
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.
Highly flexible fibre probes allow intracorporeal
lithotripsy in bladder, ureter and kidney
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 Main Advantages Technical Characteristics Overview
Extremely effective
Fragments even the hardest stone material, while softer stones can be selectively
precision treated
Extremely safe
The laser’s Antiperforation Mode avoids any unintentional coagulation or
perforation of soft tissue
Extremely versatile - within its discipline
This laser can only destroy stones - but does this remarkably well and without the
many possible complications seen, for example, with Ho:YAG lithotripters
Extremely flexible
The special fibre probes are optimised for use in combination with flexible
Ureterenoscopes (URS) and can be applied in both ureter and kidney
Easy to use
The device is preconfigured and ready to use immediately after being switched on
Highly Efficient and Safe to Use in
Urology, Gynaecology and Gastroenterology
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.

Fragmentation of
a Bladder Stone
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.
