<p>Surgical apparatus comprises an optical fibre (13) through which laser energy is applied to tissues for such purposes as ablation of atheroma, destruction of calculi and lithotripsy. The fibre is provided with an end-piece (4) through which it passes, and terminates flush with its distal end. For various applications at least the tip (14) of the end-piece may be made either highly reflective or highly absorptive of the laser radiation. A balloon catheter (5) may be fitted over the fibre. The end-piece may be provided with sensing means (15). <IMAGE></p> |
