ABSTRACT:
A laser energy excitation and delivery device which includes a coaxial system of tubes having an annular space therebetween. A lasing or pumping gas is provided in the annular space and subjected to radio frequency discharge which results in the generation of laser radiation. The resulting laser radiation is propagated through and delivered from a section of the device which includes an extension of the innermost tube or an extension of each of the tubes. One embodiment of the device includes a central passageway though which various materials, including a guide wire, can pass. The device has particular utility for medical and surgical procedures.
