The hand piece is longitudinally tapered and is generally wedge-shaped in its width so as to form a tool which can be comfortable grasped by a surgeon for purposes of more accurately controlling the laser beam applied through the laser catheter. The hand piece includes an internal switching mechanism which may be conveniently activated by pressing flexible panels positioned on the sides of the hand piece. The hand piece is constructed of inexpensive plastic materials and is designed to be disposable after a single use. | |
