An expandable intravascular medical device is provided. The medical device comprises an expandable tubular body that includes an integrated resilient support structure that forms a plurality of electrically conductive regions to which the lead(s) is coupled. The tubular body further includes at least one electrically insulative element disposed between the conductive regions. In one embodiment, the support structure is skeletal in nature, e.g., it can be formed of a mesh, braid, or coil. The conductive regions can be variously formed by the support structure. For example, the support structure may comprise electrically conductive sub-structures that form the conductive regions. In this case, the sub-structures may be mechanically linked together by the insulative element(s), or they can be directly linked together, and the insulative element(s) can take the form of insulative layer(s) disposed on one or more of the conductive sub-structures. As another example, the support structure can have a conductive core and insulative material disposed over portions of the conductive core. In this case, the exposed core portions form the conductive regions, and the unexposed core portions form the insulative element(s). |
