Abstract: A device is provided for illuminating a tissue surface to be treated. The device includes a catheter, a light emitting diode in the distal tip 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. An external source of energy is provided for supplying energy to the light emitting diode and for controlling the light emitting diode.

Abstract: 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.

Abstract: The present invention provides an improved apparatus and method for the treatment of body cavities and damaged vessels using electromagnetic energy. A device and apparatus according to the invention may be used to irradiate a tissue surface internal to the body, for example, for treatment of an aneurysm, tissue reconstructing, or removal of an anomaly in a blood vessel. Light energy may be radiated from an implantable and retrievable biocompatible matrix into which is mounted a plurality of electromagnetic energy sources, such as light emitting diodes or the like.
