1. Apparatus for diagnosis or treatment of a vessel or organ, the apparatus comprising:
- a catheter having a distal extremity;
at least two optical fiber sensors affixed within the distal extremity; and
processing logic operatively coupled to receive an output of the optical fiber sensors, the processing logic programmed to compute a multi-dimensional force vector corresponding to a contact force between the distal extremity and a tissue wall of the organ or vessel, the processing logic adapted to generate an output based on the multi-dimensional force vector to guide and control the distal extremity.

Abstract
Apparatus is provided for diagnosing or treating an organ or vessel, wherein a device having at least two optical fiber sensors disposed in a distal extremity thereof is coupled to processing logic programmed to compute a multi-dimensional force vector responsive to detected changes in the optical characteristics of the optical fiber sensors arising from deflection of the distal extremity resulting from contact with the tissue of the wall of the organ or vessel. The force vector may be used to facilitate manipulation of the catheter either directly or automatically using a robotic system.
