Differential covering and coating methods |
摘要 |
The present invention, in an exemplary embodiment, provides a stent, which combines many of the excellent characteristics of both silicone and metal stents while eliminating the undesirable ones. In particular, a principal objective in accordance with the present invention is to provide a family of stents where the relative hardness/softness of regions of the stent can differ from other regions of the stent to provide additional patient comfort and resistance to compression forces. Exemplary embodiments provide a stent that is covered so as to provide certain predefined characteristics. In particular, a covered stent is provided that is coated internally such that the outer scaffolding surface of the stent has enhanced friction points while the internal surface exemplifies certain characteristics.
