Abstract:
An intraluminal device is provided with a porous structure. The porous structure may be loaded with a bioactive substance to treat surrounding tissues after the intraluminal device has been implanted. The porous structure may be made by depositing a metal film on a foam structure using chemical vapor deposition. Porous structures may also be made by sintering or applying a ceramic layer to the intraluminal device. An intraluminal device is also provided with a ceramic material applied to generally straight portions of the device structure but not to portions adapted to bend. One advantage is that the ceramic material is less likely to fracture since it is applied to regions that experience less strain.
