Vascular stent which is specially designed for the multiple drug loading and better drug elution

摘要

As the blood vessel stent 1, which is used for the multiple drug loading and more effective blood vessel stent for drug release is percutaneous coronary intervention in accordance with the invention, the zigzag of (zigzag) are connected to form a plurality of strut arrangement 120 is a cylindrical to a ring in and ring structure 100 formed made a (loop) including a plurality in the longitudinal direction of the stent (1), are formed each between the ring structures 100, the ring structure 100 in the struts 120 in the stent (1) a plurality of containing and, each of the ring structure 100 in a link structure (200) connected to each other in the longitudinal direction along the length of the stent (1) of the same ring structure ( is connected via a strut 120 and the connection end (110) adjacent in the 100), the strut (120) is formed with a drug storage slot 121 along its longitudinal direction a plurality of medicament are made and the layers multiple stacked therein it is possible to be. Blood vessel stent of the invention has the advantage that the resulting demands on the drug release for a long time by storing a large amount of the drug in a single layer (單層) or multi-layered (多層 式) for preventing restenosis, in a very high flexibility bent can be easily installed in a blood vessel, by providing a mirror type (mirror-type) link structure of the open type to allow Causes stent blockage (stent jail) in the branched portion of the blood vessel to the procedure back to coronary intervention into the branched blood vessels without the there is an advantage. ; Coronary artery intervention, stents, balloons, balloon, cobalt chrome, stainless steel, drug stores, vascular restenosis, mirror-type, multi-layer, multi-layer
