Luminal stent, holding structure therefor and device for attaching luminal stent

摘要

A luminal stent is a tubular body formed by knitting a sole yarn of a bioresorbable polymer fiber, such as fiber of polylactic acid, polyglycol acid or a polylactic acid-polyglycol acid copolymer. When introduced into and attached to the inside of the vessel by a catheter fitted with a balloon, the tubular member may retain its shape for several weeks to several months after attachment and subsequently disappears by being absorbed into the living tissue. In this manner, the luminal stent is not left as a foreign matter semi-permanently in the living body without producing inflammation or hypertrophy in the vessel. There is also provided a method for attaching the luminal stent in the vessel.
