| titleOfInvention | Biodegradable Stent with Biodegradable Drug Delivery Film |
| abstract | The present invention relates to a biodegradable stent having a biodegradable drug delivery film. Biodegradable stents having a biodegradable drug delivery film of an embodiment of the present invention is a plurality of stretchable struts arranged in a radially expandable and zigzag connection, and the plurality of stretchable struts connected to each other in the longitudinal direction and the diameter And a cylindrical expandable stent part including a plurality of stretchable strut joints in a direction, and open at both ends of a biodegradable material that decomposes after a period of time in the lumen or blood vessel of the human body, and surrounding the expandable stent part. And a plurality of micro holes and a film part made of a biodegradable material which is decomposed within a shorter period than a period in which the expandable stent part is decomposed. According to the present invention, the biodegradable drug delivery film provided on the surface of the stent expanded in the blood vessel is stretched in the direction of the diameter of the blood vessel as the stent expands and adheres to the blood vessel wall so that when the stent is expanded, many blood clots in the blood vessel wall come off and enter the bloodstream. It can prevent migration, and if the vessel is damaged when the stent is expanded in the vessel, it continuously releases the drug carried on the film and / or stent, while preventing the formation of blood clots and vascular narrowing in the vessel, while forming a plurality of micro holes. The biodegradable film is first decomposed and then the stent is decomposed so that the film and the stent can be safely extinguished in the blood vessel. |
