1. A device for applying a laser energy beam to a selected body site, comprising:

  • an elongated, laser energy transmitting conduit having a proximal end region with a proximal end defined thereon and a distal end region with a distal end defined thereon and defining a laser energy path; and

    a hollow element mounted on said distal end region of said conduit, said element including;

    a cavity defined therein within which said distal end region of said conduit is received;

    a closed distal end wall blocking any transmission of a laser energy beam distally from said element coaxial with said laser energy path at said distal end of said conduit;

    a laterally open aperture defined in said element and communicating with said cavity, said aperture being open to fluid communication from outside said element through said aperture into said cavity; and

    beam splitting means, disposed entirely within said cavity, for receiving laser energy transmitted through said conduit and for directing at least a first portion of said received laser energy as a laser energy beam exiting said element along a lateral beam path through said aperture.
