In one embodiment, an oxidation catalyst comprises a catalytic material disposed on a support. For the acquisition of each individual image, the sample is provided with a marker pattern, in which individual markers can be imaged in the form of spatially separable light distributions through the imaging onto the image sensor. In addition, each structural component has at least one mechanical connector operatively associated therewith to provide at least one point of mechanical connection. The interactive computing system may process the operation, and return the results to the computing device from which the message was received. An example stent graft may include a main body stent graft defining a lumen that has a first end and a second end, a diaphragm coupled to the main body stent graft, where the diaphragm defines at least three openings and at least three stent graft extensions each defining a lumen, where a first end of each of the three stent graft extensions is coupled to one of the three openings.
