Abstract

A luminal stent inserted and fixed in a vessel, such as a blood vessel, so as to maintain the shape of the vessel, and a device for inserting and fixing the luminal stent, are disclosed. The luminal stent is formed of a yarn of bioabsorbable polymer fibers, which yarn is shaped in a non-woven non-knitted state in, for example, a meandering state, around the peripheral surface of an imaginary tubular member. The bioabsorbable polymer includes polylactic acid, polyglycol acid, polyglactin, polydioxanone, polyglyconate, polyglycol acid and a polylactic acid-.epsilon.-caprolactone copolymer. The device for inserting and fixing the luminal stent consists in a catheter having a balloon-forming portion in the vicinity of a distal end thereof and the luminal stent fitted on the balloon-forming portion and affixed to the balloon-forming portion by a bio-compatible material, such as an in vivo decomposable polymer, such as polylactic acid, water-soluble protein or fibrin sizing agent.
