STENT, STENT DELIVERY SYSTEM, AND STENT MANUFACTURING METHOD
A tubular stent formed of at least one wire includes proximal and distal ends and an intermediate part that includes annular windings extending in a circumferential direction around a longitudinal axis of the stent and arranged in a direction along the longitudinal axis. Each of the windings has hill-shaped sections bent toward the proximal end and valley-shaped sections bent toward the distal end, alternately arranged in the circumferential direction. All sections form intersections helically arranged around the longitudinal axis. The hill-shaped sections of one of the windings and the valley-shaped sections of the neighboring winding overlap each other at the intersections in a radial direction of the stent. Distances in the direction of the longitudinal axis between the hill-shaped and the valley-shaped sections of a first winding forming at least one of the proximal and distal ends are different from each other in a circumferential direction of the stent.

INFORMATION PROCESSING APPARATUS AND INFORMATION PROCESSING METHOD
A first examination identification unit identifies examination data including predetermined diagnosis data from among multiple pieces of examination data held in a recorder. A second examination identification unit identifies respective pieces of examination data of multiple examinations performed on a same patient after an examination date included in the examination data identified by the first examination identification unit from among the multiple pieces of examination data held in the recorder. An information acquisition unit acquires, based on multiple pieces of examination data identified by the first examination identification unit and the second examination identification unit, a period from the examination date included in the examination data identified by the first examination identification unit until the complete cure of the patient and the number of examinations performed until the complete cure of the patient. A derivation unit derives an appropriate examination interval and an appropriate number of examinations based on the period and the number of examinations acquired by the information acquisition unit from the plurality of pieces of examination data of the patient.
