1. An imaging device comprising:
- an outer sheath including an optically clear annular section at a distal end thereof;
a hollow flexible shaft configured to be inserted within the outer sheath and rotated relative thereto, the hollow flexible shaft having an imaging window therein;
an optical fiber extending within the hollow flexible shaft substantially along the central axis, a distal tip of the optical fiber attached to the hollow flexible shaft and aligned with the imaging window so as to transfer an optical coherence tomography signal through the imaging window.

Abstract
An imaging device includes a hollow flexible shaft having a central longitudinal axis and an imaging window therein. An optical fiber extends within the hollow flexible shaft substantially along the central axis. A distal tip of the optical fiber is attached to the hollow flexible shaft and aligned with the imaging window so as to transfer an optical coherence tomography signal through the imaging window. A handle is attached to the hollow flexible shaft configured rotate the hollow flexible shaft at speeds of greater than 1,000 rpm.

13. A method of imaging a body lumen, the method comprising:
-
inserting an outer sheath into the body lumen, the outer sheath having an optically clear annular section at a distal end thereof; inserting an imaging device into a lumen of the other sheath, the imaging device including a hollow flexible shaft having a central longitudinal axis with an imaging window therein and an optical fiber extending within the hollow flexible shaft, wherein a distal tip of the optical fiber is attached to the hollow flexible shaft and aligned with the imaging window, the optical fiber extending substantially along the central longitudinal axis; rotating the hollow flexible shaft within the lumen of the outer sheath; and collecting images of the body lumen through the imaging window and the optically clear annular section with the optical fiber as the hollow flexible shaft rotates. - View Dependent Claims (14, 15, 16, 17, 18, 19)
