A device is provided for illuminating a tissue surface to be treated. The device includes a catheter, a light emitter to emit light from the distal end of the catheter, and a distal cap disposed over the distal end of the catheter. The device includes a handle connected to the proximal end of the catheter. The light emitter can include a light guide extending through an interior channel of the catheter, and an external source of light operatively connected to the light guide. The light emitter can include a light emitting diode in the handle, or the light emitter can include a light emitting diode in the distal end of the catheter.
