1. A laser therapy system to permit delivering therapeutic laser energy from different lateral positions, the laser therapy system comprising:
an endoscope defining a longitudinal passage;
an optical fiber, including a distal portion that is configured to be inserted into a patient via the longitudinal passage of the endoscope,
at least one actuator, the at least one actuator configured to controllably actuate the distal portion of the optical fiber to be adjustably positioned, at least laterally, within the longitudinal passage at a selected position of a plurality of laterally displaced positions within the longitudinal passage of the endoscope, wherein the adjustably positioned optical fiber is configured to direct therapeutic laser energy to the patient; and
a stabilizer stage within the longitudinal passage, the stabilizer stage including, at the plurality of laterally displaced positions, a plurality of grooves or recesses each shaped to receive and stabilize the distal portion of the optical fiber after being positioned by the at least one actuator.
