Apparatus (10) for directing laser energy from a source (28) to a vascular occlusion is disclosed comprising a catheter (12) and a bundle of solid optical fibres (20) disposed in an annular array about the outer wall of the catheter. The distal end (40) of the fibre bundle is bevelled at an angle so as to focus the laser energy to a single focal point (P). |
