Laser radiation delivered to a treatment area causes vapo.pi.zation of a substantially greater volume of tissue than the volume of residual coagulated tissue The laser radiation may have a wavelength of about 300 m to about 700 nm, may be used with a smoke suppressing ir.pi.gant, may have an average irradiance greater than about 5 k.iota.lowatts/cm2, and may have a spot size of at least 0 05 mm2 A laparoscopic laser device, for use with an insufflated bodily cavity, 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-vapo.pi.zation-capable laser energy and capable of delive.pi.ng laser energy along a laser energy path extending away from the laser energy delivery element A smoke-suppressing liquid pathway extending along the elongate body may be coupleable to a source of a smoke-suppressing liquid |
