Artificial sapphire probe for contact photocoagulation and tissue vaporization with the Nd:YAG laser.
A contact artificial sapphire, developed for use with the Nd:YAG laser, allows the performance of open surgery (laser probe) and has endoscopic applications for the treatment of gastrointestinal bleeding (micro laser tip) and tumors (micro laser rod). Advantages of this contact irradiation include precision of surgical technique, minimal tissue damage, and excellent hemostatic and cutting capabilities, with low backscattering of laser energy.

Nd:YAG laser endoscopic photocoagulation for upper gastrointestinal bleeding.
To appraise the success of neodymium:yttrium-aluminum-garnet laser photocoagulation for the endoscopic control of major upper gastrointestinal bleeding, 19 patients who fulfilled all the criteria of this study underwent laser therapy. Initial hemostasis was achieved in 17 patients (89%). The two patients continuing to bleed underwent surgery but died. Rebleeding occurred in five patients, with laser photocoagulation successful in two and surgery in another two. Nd:YAG lasers offer a safe, effective method for controlling bleeding and, it is hoped, will decrease the morbidity and need for emergency surgery.
