PROBLEM TO BE SOLVED: To provide medical devices.SOLUTION: An apparatus comprises an insertion tube, which has a distal end configured for insertion into the proximity of tissue in a body of a patient and contains a lumen having an electrical conductor for conveying electrical energy to the tissue. The apparatus further includes a conductive cap attached to the distal end of the insertion tube and coupled electrically to the electrical conductor, where the conductive cap has an outer surface. In addition, there are a multiplicity of optical fibers contained within the insertion tube, each fiber terminating in the proximity of the outer surface of the cap and being configured to convey optical radiation to and from the tissue while the electrical energy is being conveyed to the tissue. |
