Thulio offers a wide range of application modes, adapting to your needs and enabling smoother procedures.
Dusting mode
Fragmenting mode
Captive Fragmenting mode
Enucleation mode
Soft Tissue mode
Flexible Short Pulse mode
Flexible Long Pulse mode
Dusting mode
Low pulse energy, long pulse duration and high frequency provides fine and fast dusting capabilities that disintegrate particles in 125 μm and smaller.1
Fragmenting mode
High pulse energy, short pulse duration and low frequency for breaking larger or hard stones.
Captive® Fragmenting mode
High pulse energy, long pulse duration and low frequency for breaking larger or hard stones.
Scientifically proven to provide up to 55% reduced retropulsion*2 during fragmentation. The Dornier
Captive mode was developed to decrease the stone
movement during application – potentially reducing
correlating lithotripsy time.
