Document Type and Number:
WIPO Patent Application WO/2020/250752
Kind Code:
A1
Abstract:
An optical therapy/diagnosis device (1) comprises a catheter shaft (10), and an optical waveguide (20) that is arranged in a lumen (11) of the catheter shaft (10) and can be advanced/retracted in the longitudinal direction of the catheter shaft (10), wherein: the optical waveguide (20) is one that guides a first ray (51) and a second ray that have different wavelengths; the catheter shaft (10) is provided with a side exit window (12) where the first ray (51) and the second ray exit to the side, and a distal exit window (13) where the first ray (51) exits in a distal direction; and the optical therapy and diagnosis device (1) is provided with a first mirror surface (31) that is disposed at a distal end of the optical waveguide (20) and causes the first ray (51) to be reflected toward the side of the catheter shaft (10), and a second mirror surface (32) that is disposed at a location that is an inside surface (10a) of the catheter shaft (10) and is more to the distal side than a distal end of the side exit window (12) and causes the first ray (51), which has been reflected at the first mirror surface (31), to be reflected toward the distal direction of the catheter shaft (10).
