Abstract

According to one aspect of the present disclosure for achieving the above-described object, a multimodal imaging catheter inserted into the body to acquire information of an internal body tissue for achieving the above-described object is disclosed. The multimodal imaging catheter may include an imaging core including a double clad fiber and a focusing device, the imaging core transfers light to the internal body tissue and collects information within the internal body tissue; and an imaging sheath including the imaging core therein to protect the imaging core from an external environment and to separate the internal body tissue and the imaging core during an imaging operation of the multimodal imaging catheter for the internal body tissue. Also the imaging sheath includes a plurality of tubes coupled along a longitudinal direction of the multimodal imaging catheter, a first tube corresponding to an imaging window region through which light generated according to a rotation of the focusing device passes among a plurality of tubes of the imaging sheath is made of a first material in which a maximum intensity of autofluorescence when excited light is irradiated is smaller than a standard deviation of background noise when excited light is not irradiated, in order to reduce autofluorescence generated by the imaging sheath itself, a second tube corresponding to a distal tip region from which the light is emitted to the internal body tissue among a plurality of tubes of the imaging sheath is made of a second material in which a maximum intensity of autofluorescence when excited light is irradiated is larger than a standard deviation of background noise when excited light is not irradiated, and when the multimodal imaging catheter is inserted into a body, the first tube in the imaging sheath is located proximal to the internal body tissue, and the second tube may be located distal to the internal body tissue.
