Abstract: A stent delivery system includes: a stent delivery device configured to carry a stent to a stenosis and indwell the stent, an observation device configured to observe the stenosis, and one or more processors comprising hardware, the one or more processors being configured to: acquire an observation image from the observation device, and determine at least one stent candidate to be placed in the stenosis based on the observation image.

Abstract: A two-dimensional light deflector includes first and second deflectors that deflects a light beam, and a fixing member directly fixing both the first and second deflectors. The first deflector includes a light radiating portion, supported oscillatably around a first axis, to radiate the light beam toward the first axis along a first plane perpendicular to the first axis. The second deflector includes an oscillatable reflecting face that reflects the light beam. The reflecting face is inclined by 45 degrees to the first axis and a second axis coincident with a principal ray of the light beam from the radiating portion. The reflecting face is oscillatably supported around a third axis passing through an intersection of the first and second axes and perpendicular to both the first and second axes.

Abstract: Provided is a high-frequency treatment tool including: a sheath having an inner hole that passes therethrough in a longitudinal direction; a first electrode portion that is formed in a rod shape, that passes through the inner hole of the sheath to protrude from a distal end of the sheath, and that is configured to apply a high-frequency current; a second electrode portion that is disposed at a position at which the second electrode portion is electrically connected with the first electrode portion; and a power source that uses the first electrode portion as a negative electrode, that uses the second electrode portion as a positive electrode, and that supply a current between the first electrode portion and the second electrode portion so that a state in which attached matter attached to the first electrode portion is lifted from the first electrode portion due to osmosis is created.

Abstract: A stent includes a first tubular unit that has a cylindrical tubular shape and a mesh circumferential surface; and a second tubular unit that has a cylindrical tubular shape and a mesh circumferential surface, and is connected to the first tubular unit in a longitudinal axis direction of the stent. The first tubular unit has a first-first direction bent portion which is bent to be convex toward the first direction side that is one side of the longitudinal axis direction, the second tubular unit has a second-second direction bent portion which is bent to be convex toward the second direction side that is the other side of the longitudinal axis direction, and the first-first direction bent portion and the second-second direction bent portion form a first connecting portion that is connected so as to be relatively movable.

Abstract: An endoscope system includes a direct-view endoscope configured to capture images, a treatment tool configured to be inserted into the endoscope, and a controller comprising hardware, the controller being configured to control a drive device to drive the endoscope and the treatment tool, to control driving of the endoscope to locate the endoscope inserted into a lumen in the vicinity of a nipple, to control driving of the treatment tool to move the nipple using the treatment tool, to acquire a first captured image of the nipple from the endoscope, and to predict a shape of a biliary duct connected to the nipple in the first captured image based on biliary duct shape information comprising a standard image of the nipple that is associated with a standard shape of the biliary duct.
