The Device at a Glance

The new Litho EVO device represents the evolution of Quanta System low power Holmium line (Litho), improving the performances of its predecessors and adding some of the innovations recently introduced with our high power Holmium line.

Litho EVO is designed for enhanced versatility in lithotripsy and soft tissue surgery.

The user guides selection of emission parameters, to save their favorite settings and to switch immediately between different settings thanks to the double footswitch. The use of the MasterPULSE and Vapor Tunnel technologies further empowers the surgeon with advanced treatment tools.


 Reducing retropulsion and modifying tissue cutting gets easier: instead of trying multiple different settings, start with your preferred ones and then adjust the MasterPULSE to tune the effect of laser emission based on your visual feedback. 

Experience fast and more intuitive adjustment of laser settings thanks to the 7 pulse width levels (compared to the traditional 3 steps of the other holmium lasers). 


 Consisting of a Single Specific Long Pulse, this emission mode allows limited retropulsion and fine stone ablation.

The Vapor Tunnel is designed in order to use the minimum peak power in accordance with selected output settings.

High Power with Small Fibers

 Litho EVO device is designed for high performances already with small standard fibers (allowing almost full power even with the smallest fiber diameters). Thanks to this feature, the user shall not refrain from having fiber flexibility and high emission power at the same time.

Guided Modality

 Quanta System enhanced the user-friendliness of this low power system with a guided modality to automatically select proper settings based on the intended treatments

Apart from stone lithotripsy and soft tissue surgery in urology, a dedicated preset is provided also for the fragmentation of biliary stones.

Double Footswitch

The double footswitch enables surgical versatility, by allowing the surgeon to switch from one treatment mode to another immediately instead of asking to a nurse to adjust the settings.

For instance, the user may switch from fragmentation to popcorning or from incision to coagulation modes, speeding up the treatments. 

Wide Range of Fibers

A great versatility in applications requires a wide range of delivery probes. For this reason, Litho EVO laser is compatible with different fiber diameters (200-1000µm) and types.

Apart from standard fibers, our portfolio includes also other fiber models, such as the ball tip fibers (for easier insertion into an already-bent scope).

Compact Design

The light weight and compact tower design of the device allow easy transportation and storage in the hospital, with limited space needed in the OR during the surgical procedure. These features make Litho EVO laser suitable for use in different hospitals and for recurrent relocations, without affecting the performances and condition of the device. 

Wide Range of Applications

Its limited depth of penetration (0.3-0.4mm), together with the incision and hemostasis properties of this radiation, enables a large variety of surgical treatments. Apart from stone fragmentation (urolithiasis, gallstones) and urology treatments (e.g. strictures, tumor resection), Litho EVO device can perform effective soft tissue surgery in other medical specialties, including General Surgery, Arthroscopy and ENT.
