Abstract
A medical apparatus including implantable elongate probes for emitting diffused light energy within the interior of a tissue body to provide a uniform light dosage to the tissue body. In one particular embodiment, the probes may include a plurality of LEDs or VSCEL devices interspaced along the probe shaft. The invention further provides an planar or shaped alignment grid for aligning one or more probes within the tissue body.
