A stent comprising a cylindrical/tubular body knitted of polymer filaments which is capable of being absorbed by an organism and is constituted of polylactic acid, polyglycolic acid, or copolymer of said acids. This cylindrical/tubular body is kept unchanged in configuration for several weeks to several months after inserted into and fixed to a vessel through a catheter having a balloon and afterward disappears while absorbed into the tissue of an organism. The invention provides a stent to prevent the vessel from being attacked by inflammation or hypertrophy and to disappear without remaining as semi-permanent foreign matters in an organism and device for mounting the stent. |
