Abstract
An apparatus and method of aspirating vapors during laser surgery couples a vaporizing device with a source of vacuum. The apparatus includes an aspiration connector insertable into the vaporizing device and coupled to an optical waveguide disposed along a bore of the device. An aspiration pathway extends along with the optical waveguide in the bore of the vaporizing device forming a compact single passageway vaporizing device with aspiration capability. Vacuum control points are provided along the aspiration pathway to adjust the vacuum at an end where the vapors are formed.
