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.
