Use: For Endoscopic fragmentation of Biliary and Urinary Stones

The AUTOLITH^® is a high output, computer controlled lithotripsy device which provides greater patient safety, increased stone treatment effectiveness and ease of operation. It is indicated for Biliary and Urinary stone treatments.

• Easy to understand and use. Minimal set-up required and lightweight transport. Can be hand carried from one location to the next. Wearing safety goggles is not required.
• Designed with complete consideration to today’s economical contraints and budgets.
• Long lasting and durable with infrequent servicing required.
• Only 3 probe sizes to consider makes reordering the disposables a simple task.
• The computer controlled AUTOLITH^® provides a precise balance of pulse energy based on the probes size used. This prevents power overload to the probe which increases patient safety and extends the life of the disposable probe.
• The AUTOLITH^® monitors the effects of the disposable probe operation to estimate probe life.

Electrohydraulic Lithotripsy (EHL)

Electrohydraulic lithotripsy (EHL) was the first form of contact lithotripsy developed and dates back to the early 1970’s. EHL can fragment calculi of all compositions.

Electrohydraulic lithotripsy, the first technique used for intracorporeal stone fragmentation, utilizes a fine probe containing two electrodes (BiPolar Technology) separated by an area of insulation. An electric current is passed between two electrodes creating a tiny spark, which vaporizes the water (.9% normal physiological saline) at the end of the probe. This spark gap creates a cavitation bubble, which rapidly expands, creating a shock wave. Once the cavitation bubble collapses a secondary pressure wave is created which is then transmitted to the closely adjacent stone. At the stone-saline interface, the difference in acoustic impedance causes energy to be released, resulting in stone fragmentation. This process is exactly similar to (ESWL) shock wave lithotripsy in generating a spark gap, however, the difference in EHL is that the shock wave is not focused, so the stone must be placed where the shock wave is generated.
