Abstract
Systems and methods can be used for treating soft tissue. The system can include a laser configured to emit pulsed laser energy that can be modulated to maximize the ablation efficiency during the cutting, incision, or excision of soft tissue while at the same time optimizing hemostasis and reducing collateral side effects such as tissue charring and scar formation. According to certain aspects, a coagulative laser mode power is adjusted mainly for hemostasis without dehydration, and an ablative laser mode power is optimized for providing efficient ablation.
Claims20
A laser system for treating soft tissue, comprising:
- a laser configured to emit pulsed laser energy having a wavelength in a range of 1.85 to 2.2 microns (μm) inclusive;
- and
- a controller configured to control the laser such that each pulse of the emitted pulse energy comprises two sub-pulses, wherein
- one sub-pulse of the two sub-pulses is configured to ablate and incise (ablative sub-pulse) a target soft tissue, and the other sub-pulse of the two sub-pulses is configured to coagulate the target soft tissue (hemostatic sub-pulse).
