Abstract:
A single optical fiber force-sensing assembly includes a catheter configured to detect both axial and bending tip displacement. The catheter includes a flexible structure located adjacent to a distal tip portion of the catheter. The single optical fiber within the catheter defines a first reflective surface. A second reflective surface is located closely adjacent to the first reflective surface.
