PROBLEM TO BE SOLVED: To provide an in-vivo indwelling stent provided with a sufficient vasodilation holding force after stent indwelling, and capable of exhibiting high followability to a deformation of a blood vessel since getting flexible after a prescribed period lapses, and a living organ dilator provided therewith.
SOLUTION: This in-vivo indwelling stent 1 is formed of a linear constitutive elements and contacts closely with an in-vivo tissue by deformation in an indwelling operation into a living organism. The stent 1 is formed of a metal stent base body 2 formed substantially cylindrically of the metal linear constitutive elements 21, 22, 23, and a plurality of linear constitutive elements 3 made of a biodegradable material with one end and the other end joined to the metal linear constitutive elements.
