Abstract
Laser ablation devices and related systems and methods may have laser outputs with multiple wavelengths. Laser ablation devices may include a laser energy source that can emit two or more laser outputs with different wavelengths. Some laser ablation devices include a processor to control the laser energy source to cause the laser energy source to emit a target wavelength blend with the laser outputs.
Claims20
A method for tissue ablation, the method comprising:
- receiving user input indicating a surgical target, the surgical target comprising a first area and a second area within the first area, wherein the first area is larger than the second area;
- emitting a first laser output with a first wavelength, the first laser output delivering sufficient power to cause sub-critical damage to the first area;
- and
- emitting a second laser output with a second wavelength, the second laser output delivering sufficient power to cause necrosis to the second area.
A laser ablation system comprising:
- a laser energy source configured to emit at least two laser outputs with different wavelengths;
- a laser applicator coupled to the laser energy source via a laser fiber, the laser applicator configured to output laser radiation at an surgical target, the surgical target comprising a first area and a second area within the first area, wherein the first area is larger than the second area;
- a processor coupled to the laser energy source;
- and
- a memory coupled with and readable by the processor and storing therein instructions that, when executed by the processor, cause the processor to:
- receive user input indicating the surgical target;
- control a first laser output with a first wavelength to be emitted by the laser energy source, the first laser output delivering sufficient power to cause sub-critical damage to the first area;
- and
- control a second laser output with a second wavelength to be emitted by the laser energy source, the second laser output delivering sufficient power to cause necrosis to the second area.
A non-transitory computer-readable medium including instructions that when executed by one or more processors of a tissue ablation system cause the tissue ablation system to:
- receive user input indicating a surgical target;
- control a first laser output with a first wavelength to be emitted by a laser energy source of the tissue ablation system, the first laser output delivering sufficient power to cause sub-critical damage to a first area;
- and
- control a second laser output with a second wavelength to be emitted by the laser energy source, the second laser output delivering sufficient power to cause necrosis to a second area.
