Abstract
An apparatus for ablating biological tissue having a deflectable ablation area including an elongated catheter having a distal end, a proximal end, and an elongated body portion. A plurality of optical fibers extend between the proximal and distal ends of the catheter. The distal ends of all of the plurality of optical fibers define an ablation area at the distal end of the catheter. The catheter includes a device for selectively deflecting the distal ends of all of the optical fibers so that at least a portion of the ablation area extends beyond an area defined by the cross-sectional area of the catheter while the amount of light energy over the entire ablation area remains constant.
