Abstract: An eye movement feature amount calculating system includes: a moving state input unit that inputs moving state values in a time series indicating a moving state of an eye of an examinee; a saccade period extracting unit that extracts a saccade period in which the eye performs saccadic movement based on time-series variation of the moving state values; and a feature amount calculating unit that divides a period including at least a part of the extracted saccade period into a plurality of periods and calculates a feature amount of eye movement of the subject based on the separate periods.

Abstract: 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.

Abstract: 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.
