Abstract
A catheter suitable for the delivery of laser energy to an obstruction in a body lumen is provided, which has an expandable, elastic distal end portion containing optical fibers whose exposed distal end faces are arranged in two or more substantially concentric arrays that merge into a narrower band array of a larger diameter upon radial expansion of the elastic distal end portion. The distal end portion of the catheter is more elastomeric than the catheter body.
