Abstract
An apparatus for delivering laser energy to a target through a radiation-transmitting waveguide having a distal end terminating in a tip which is in contact with the target during delivery, while protecting the tip from heat damage, which apparatus comprises a waveguide for transmitting laser radiation and having a distal end terminating in a tip adapted to be placed in contact with the target to deliver laser energy directly to the target at the site of contact, and means for delivering a controlled small amount of liquid to the target adjacent to the tip, which small amount is just sufficient to limit the temperature at the target to not more than the failure temperature of the tip. An apparatus assembly for performing ILC incorporating a waveguide and a method for protecting the tip of a waveguide from damage is also disclosed.
