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.

The present invention automates the adjustment of an amplitude of stimulated pulses that are generated by an implanted device. Apparatus comprises a processor that communicates with the implanted device over a communications channel through a communications module. The apparatus enables the clinician to select a pair of electrodes that is contained on a lead of the implanted device. Corresponding to each iteration of the process, the processor sends a command to the implanted device in order to increment the amplitude of the stimulation pulse between the selected electrodes. Each iteration of the process corresponds to the apparatus incrementing the current value by a predetermined incremental value that can be selected by the clinician. When the current value of the amplitude equals the target value, the process is halted. Additionally, the clinician can halt process during the execution of the process by instructing the apparatus.
