Maintenance of a steam bubble during surgical ablation
First Claim
Patent Images
1. 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 ablation of the surgical target.

16. 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 couple 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 4 degrees; wherein the low-angle and high-angle of respective launches are measured with respect to a longitudinal axis of the optical fiber. - View Dependent Claims (17, 18, 19, 20)
