Abstract
A surgical method and tool for establishing a steam bubble between a fiber tip and a surgical target. The device and process capable of maintaining the steam bubble by providing a low-power, continuous-wave laser emission. Furthermore, the method and tool capable of delivering to the surgical target through the steam bubble a therapeutic laser emission providing ablation of the surgical target.
Claims20
A surgical method comprising:
- establishing a steam bubble between a fiber tip and a surgical target;
- maintaining the steam bubble by providing a low-power, continuous-wave laser emission;
- and then
- delivering to the surgical target through the steam bubble a therapeutic laser emission;
- wherein the therapeutic laser emission provides the ablation of the surgical target.
2 more elements
A surgical device comprising:
- a therapeutic laser emission source having a power output of greater than 10 Watts;
- a continuous-wave laser emission source having a power output of less than 5 Watts;
- a low angle therapeutic laser emission launch adapted to provide a therapeutic laser emission to a core of an optical fiber;
- and
- a high angle continuous-wave laser emission launch adapted to provide a continuous-wave laser emission to the optical fiber with a launch angle of greater than about 4°;
- wherein the low-angle and high-angle of the respective launches are with respect to a longitudinal axis of the optical fiber.
