Laser radiation delivered to a treatment area may be used with a smoke suppressing irrigant. A laparoscopic laser device may include an elongate body adapted for insertion into an insufflated bodily cavity. A laser energy delivery element, at the distal end of the elongate body, may be coupleable to a source of tissue-vaporization-capable laser energy and capable of delivering laser energy along a laser energy path extending away from the laser energy delivery element. A smoke-suppressing liquid may be directed generally along the laser energy path. A remote visualization device may be used to view along the laser energy path. The laser energy path can be shrouded with a circumferentially extending suction manifold so that liquid can be suctioned from the target site and away from the laser energy path. In some examples, the suction manifold is an axially extendable and contractible suction manifold.
