摘要：
Ablative catheters and methods for making and using the same are disclosed. The catheter may have a proximal end, a distal end, and a first lumen extending at least partially between the proximal and distal ends. The catheter may include at least one ablative port located adjacent to the distal end of the catheter. The catheter may include an ablative mechanism capable of ablation using an conductive fluid circulated to the ablative port through the first lumen. An expandable member may be disposed at an outer surface of a distal portion of the catheter. The expandable member may be capable of switching between a collapsed position and an expanded position using an expansion fluid circulated to the expandable member through a second lumen. In the expanded position, the expandable member may be sized and shaped to position the ablative port at a suitable distance from a wall of the vessel.
