Abstract
Laser-based systems and method for treatment of calculi. The system can include a laser configured to emit pulsed laser energy and a controller configured to control the laser. The laser can be modulated to operate in one of a dusting, fragmentation, or reduced retropulsion operational mode. One or more of these operational modes include pulses comprised of sub-pulses.
Claims20
A laser system for treating calculi, comprising:
- a laser configured to emit pulsed laser energy having a wavelength a range of 1.85 to 2.2 microns (μm) inclusive;
- and
- a controller configured to control the laser such that the pulsed laser energy is emitted as a sequence of sub-pulse groups separated in time by a pulse repetition interval, and each sub-pulse group includes at least two sub-pulses separated in time by a sub-pulse interval that is in a range of 0-10 milliseconds (ms), wherein
- each sub-pulse of the sub-pulse group has a pulse duration in a range of 0.001-5 ms inclusive,
- each sub-pulse of the sub-pulse group has an energy in a range of 0.001-1 Joules (J) inclusive, and
- the pulse repetition interval is in a range of 1-1000 ms inclusive.
3 more elements
The laser system of claim 6, wherein the total energy of the sub-pulse group is in a range of 0.5-2 J inclusive.
