High spatial resolution optical coherence tomography rotation catheter
An optical coherence tomography rotation catheter comprises a catheter body and a tubular member that rotates around a longitudinal axis in the catheter body. An optical fiber extends along an interior of the tubular member and has an optical fiber distal end. A light reflecting member is distal of the optical fiber distal end and rotates around the longitudinal axis with the tubular member. The light reflecting member includes a light reflecting surface which is spaced from and faces the optical fiber distal end and which is inclined to reflect the light from the optical fiber in a radial direction at an angle with respect to the longitudinal axis. The light reflecting member has a diameter of at most about 0.25 mm. The light reflecting surface is polished and coated with a light reflecting film.
