A catheter with at least one centering device attached near a distal end of the catheter. The centering device has at least two struts extending between a proximal end and a distal end. The centering device has a variable diameter and tends to center the distal end of the catheter, steering the catheter away from the vessel wall during insertion through the vasculature and toward the treatment site. The centering catheter may facilitate access to tortuous anatomy by preventing the catheter tip from catching on irregularities in the lumenal surface. The centering catheter may also facilitate uniform stent expansion by stabilizing the catheter during stent deployment.

A method, computer program product, and data processing system for facilitating the traversal of a hierarchy of GUI components containing components and / or containers from disparate GUI toolkits is disclosed. In a preferred embodiment, auxiliary associative data structures relating parent components in one toolkit to children in another toolkit are defined. When examining a component to determine if it has children, an appropriate associative data structure is consulted to determine if that component has a child from a disparate toolkit. In accordance with this preferred embodiment, additional associative data structures are defined, which also record the reverse “child-parent” relationship, so as to allow the GUI component tree to be traversed in both directions.

Methods and apparatus implementing systems and techniques for traversing a hierarchical layout template to accelerate a constraint-driven backtracking search for a solution of the layout template. In general, in one implementation, the techniques include identifying a shared content element constraint that defines a content requirement common to all layout structures possible in a choice substructure in a hierarchical layout template, and associating the shared content element constraint with a root node of the choice substructure in the hierarchical layout template. In another aspect, the techniques include receiving content elements to be presented according to a hierarchical layout template that includes a choice substructure including a root node having a shared content element constraint that defines a content requirement common to all layout structures possible in the choice substructure, and traversing the hierarchical layout template to generate a layout structure that accommodates the content elements, said traversing including traversing the hierarchical layout template based at least in part on the shared content element constraint associated with the root node.
