Abstract
A stent formed in a shape of a generally tubular body having a central axis. The stent has a spring function with which the tubular body is diameter-contractible toward the central axis, and the tubular body is expandable to an initial diameter after contraction. The stent maintains a configuration curved along a longitudinal direction of the stent when the stent is not inserted in a sheath. The stent is elongated in a form of a generally straight line along the longitudinal direction when the stent is inserted into the sheath. The stent, being housed in a sheath in the form of a generally straight line, is inserted into a diseased part together with the sheath, is released from the sheath, and radially expands, outwardly after release, to restore and maintain a configuration curved along the longitudinal direction of the stent.
