A light guide unit includes a light guide member and a protection member surrounding the light guide member. The light guide member includes an optical fiber having an outer diameter. The protection member is formed in a network structure by knitting a metal member having a flat cross-sectional shape by bending the metal member in a direction in which the thickness of the metal material is thin, and a gap smaller than the outer diameter is formed along the axial direction.

A laryngoscope blade which improves the transmission of light from the laryngoscope to enhance the amount of light reflected from an area of interest in a patient. The laryngoscope blade has a channel which extends at least partially though the blade and receives a light source. The channel has a substantially transparent end face which is situated towards the blade end and has an optical clement adapted to reduce the ambient light signal from the light source in the channel.

Embodiments for crossing an occlusion by controlling a guide with the aid of optical coherence tomography (OCT) data are described. Embodiments include transmitting one or more beams of radiation via one or more waveguides on a flexible substrate within a guide wire. One or more beams of scattered or reflected radiation may be received from a sample via one or more waveguides. Depth-resolved optical data of the sample may be generated based on the received beams of scattered or reflected radiation. The depth-resolved data may be used for determining at least one of a distance between the guide wire and a wall of the artery and a distance between the guide wire and an occlusion within the artery. A position of the guide wire within the artery may then be controlled based on the determined distance or distances.
