A catheter kit includes a catheter having an optical fiber, and a catheter accommodating tool which accommodates the catheter. The catheter accommodating tool has a tubular hoop, and a position adjustment mechanism provided at the hoop. The hoop has a hoop tip end portion at which a catheter tip end portion, from which laser light transmitted through the optical fiber is emitted, is disposed, and a hoop base end portion which is opposite to the hoop tip end portion. The position adjustment mechanism is provided at the hoop base end portion and changes a position of the catheter tip end portion with respect to the hoop tip end portion.

Catheter kit

A light output monitoring apparatus includes a light receiving unit, an attachment unit, an adapter, and a protective cap, and monitors a power of light output from a light emitting end of a catheter incorporating an optical fiber. The protective cap includes an insertion opening into which a part of the catheter of a predetermined range on the light emitting end side is removably inserted, includes a window portion for transmitting the light output from the light emitting end of the catheter, and is fixed in position by being inserted into a through-hole of the adapter. The adapter is fixed in position by being attached to the attachment unit.

A catheter kit includes a catheter having an optical fiber, and a catheter accommodating tool which accommodates the catheter. The catheter accommodating tool has a tubular hoop, and a protection cap which is provided to the hoop. The protection cap has a transmission window through which laser light L output from the catheter passes.

A light measurement device measures the intensity of laser light output from a catheter tip end portion of a catheter having a built-in optical fiber. The light measurement device includes a light receiving part which receives the laser light output from the catheter tip end portion and a mounting part which is disposed at a position facing the light receiving part. The mounting part defines a position of a tubular hoop, which accommodates the catheter, with respect to the light receiving part. In a state in which the position of the hoop is defined by the mounting part, the light measurement device obtains the intensity of the laser light by inputting the laser light to the light receiving part.
