Catheter probe arrangement for tissue analysis by radiant energy delivery and radiant energy collection

A catheter tip apparatus arranged in a catheter for the delivery and collection of an energy signal to permit subsequent computerized analysis of body tissue by the collected signal, comprising:

• an elongated housing having a longitudinal axis of rotation, said housing having a first reflective surface disposed thereon;
• a second reflective surface disposed on said housing distally of said first reflective surface and in axial alignment therewith;
• and
• a first light conductive fiber in light-coupled communication with said first reflective surface and a second light conductive fiber in light-coupled communication with said second reflective surface, said first light conductive fiber in communication being in communication with a controlled analytical-light-generating source and said second light conductive fiber being in communication with a light-collection analysis device.
