    • A stent for intracorporeal retention is inserted in a human body, for instance, inside an airway, esophagus, or bile duct, and used for preventing a bore of the internal organs described above from being occluded. With this stent, discharge from the airway does not easily adhere to, nor deposit on, the internal surface of the cylindrical body, so that the occlusion thereof can effectively be prevented and, at the same time, granulation does not easily occur and, for this reason, occlusion of the airway can be prevented, which insures a high degree of safety for a human body. This stent has a hollow cylindrical body 2 made from silicone rubber with both edges opened and the internal surface of this cylindrical body is processed in any of the following ways: (a) coating with a silicone resin, (b) adhesion of a fluorine-based resin tube, or (c) chemical deposition of polyparaxylylene or a derivative thereof and, at the same time, an external surface thereof is processed by (d) chemical deposition of polyparaxylylene or a derivative thereof or (e) by gradually rounding and tapering toward both edges with the tapered sections softer than other portions thereof.
    • 将用于体内保留的支架插入人体内,例如在气道,食道或胆管内部,并用于防止上述内脏器官的孔堵塞。 使用该支架时,从气道排出不容易附着在圆筒体的内表面上,也不会沉积在圆筒体的内表面上,从而可以有效地防止其堵塞,同时造粒不容易发生,对于 因此,能够防止气道的闭塞,从而确保人体的高度的安全性。 该支架具有由硅橡胶制成的中空圆柱体2,两个边缘均打开,并且该圆柱体的内表面以下列方式之一进行加工:(a)用硅树脂涂覆,(b) 或(c)聚对二甲苯或其衍生物的化学沉积,同时其外表面通过(d)聚对二甲苯或其衍生物的化学沉积或(e)通过逐渐变圆和渐缩 朝向具有比其他部分更软的锥形部分的两个边缘。
