Abstract
A system is provided to position an energy delivery handpiece a desired distance from a treatment site while at the same time protecting the handpiece, and energy transmitting optical fibers, from soiling due to tissue debris. The system includes one or more energy transmissive members that are formed from a material that allows the passage of electromagnetic (e.g., laser) energy therethrough. The energy transmissive members can be removably and replaceably attachable to one end of a spacer member. An opposite end of the spacer member is mountable to the energy delivery handpiece. The energy transmissive member is effective protect the handpiece from tissue eruptions. In one embodiment the energy transmissive member also is effective to focus electromagnetic energy upon the treatment site.
