Abstract
A catheter, comprising: a drive cable having cylindrical opening extending from a proximal end to a distal end along a longitudinal axis thereof; an imaging probe having an optical fiber arranged inside the drive cable and a distal optics assembly fixedly attached to the drive cable at the distal end thereof; a first radiopaque marker arranged at a distal end of the drive cable at a position distal and parallel to the distal optics assembly; and a second radiopaque marker arranged at a predetermined distance from the distal end of the drive cable at a position proximal to the distal optics assembly. The second radiopaque marker is arranged concentric or coaxially to the longitudinal axis in a space between the longitudinal axis and an outer surface of the drive cable.
