Abstract: 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.

Abstract: Some embodiments of an electrical stimulation system employ wireless electrode assemblies to provide pacing therapy, defibrillation therapy, or other stimulation therapy. In certain embodiments, the wireless electrode assemblies may include a guide wire channel so that each electrode assembly can be advanced over a guide wire instrument through the endocardium. For example, a distal tip portion of a guide wire instrument can penetrate through the endocardium and into the myocardial wall of a heart chamber, and the electrode assembly may then be advanced over the guide wire and into the heart chamber wall. In such circumstances, the guide wire instrument (and other portions of the delivery system) can be retracted from the heart chamber wall, thereby leaving the electrode assembly embedded in the heart tissue.
