A new wave guide for use with a CO2 delivery system for laparoscopic surgery.

This study assessed the performance of the Heraeus LaserSonics InfraGuide with the 250Z CO2 laser in 46 patients undergoing laparoscopic surgery. Procedures included vaporization of endometriosis, adhesiolysis, ovarian cystectomy, uterosacral ligament transection, salpingoplasty, fimbrioplasty, neosalpingostomy, ectopic linear salpingostomy and myomectomy. The InfraGuide system was effective in transmitting laser energy to the pelvis. Advantages and disadvantages of the accessory sheath, spot diameter, HeNe aiming beam and optical laser coupler are discussed. The InfraGuide offers the surgeon an additional useful laparoscopic instrument.
