In one embodiment, an apparatus includes an optical fiber that includes a fiber core with a substantially constant outer diameter of less than or equal to 250 microns extending to a distal end of the optical fiber. The optical fiber is also configured to deliver laser energy up to at least 100 watts to a target area within a patient. The optical fiber is sufficiently flexible such that the optical fiber can be moved between a first configuration in which a distal end portion of the optical fiber is substantially linear and defines a longitudinal axis and a second configuration in which the distal end portion of the optical fiber is moved off its longitudinal axis. The apparatus also includes a steering mechanism coupled to the optical fiber. The steering mechanism is configured to move the optical fiber between its first configuration and its second configuration.
