Document Type and Number:

WIPO Patent Application WO/2018/212153

Kind Code:

A1

Abstract:

An optical measurement device 1 measures the intensity of laser light L outputted from a catheter leading end section 31a of a catheter 31 having a built-in optical fiber 33. The optical measurement device 1 is provided with: a light receiving section 6 that receives the laser light L outputted from the catheter leading end section 31a; and an attaching section 7 that is disposed at a position facing the light receiving section 6. The attaching section 7 specifies, with respect to the light receiving section 6, the position of a tubular hoop 36 housing the catheter 31 therein. In a state wherein the position of the hoop 36 is specified by the attaching section 7, the optical measurement device 1 obtains the intensity of the laser light L by inputting the laser light L to the light receiving section 6.
