  • Patent number: 8473067
    Abstract: Devices, systems, and methods provide for intravascular or extravascular delivery of renal denervation therapy and/or renal control stimulation therapy. Wireless vascular thermal transfer apparatuses and methods provide for one or both of production of current densities sufficient to ablate renal nerves and terminate renal sympathetic nerve activity, and production of current densities sufficient to induce endothelium dependent vasodilation of the renal artery bed. A common apparatus may be used for both renal ablation and control of renal function locally after renal denervation.

  • Patent number: 8290600
    Abstract: Some embodiments of a cardiac stimulation system may include a plurality of electrode assemblies that are interconnected by one or more wires while at least one of the electrode assemblies (e.g., a control electrode) wirelessly receives energy through inductive coupling with a power communication unit external to the heart (e.g., a device implanted along one or more ribs). These embodiments may provide an arrangement for efficient inductive coupling from the power communication unit to the control electrode. Also, in some circumstances, the cardiac stimulation system may eliminate the need for wired leads that extend to a location outside the heart, thereby reducing the likelihood of infection that passes along the wire and into the heart.

  • Publication number: 20120232565
    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.

  • Publication number: 20120136349
    Abstract: A catheter includes a multiplicity of leads having exposed distal elements defining an anode and a cathode positionable relative to an outer wall of a renal artery. A power supply is configured to couple to the multiplicity of leads. The power supply generates a DC current that flows between the anode and cathode to create an acidic region at the anode sufficient to cause necrosis of perivascular renal nerve tissue in the vicinity of the anode, and to create a basic region at the cathode sufficient to cause necrosis of perivascular renal nerve tissue in the vicinity of the cathode. The catheter may be configured to deliver a biocompatible electrolytic fluid to each of the cathode and anode, thereby increasing an extent of perivascular renal nerve tissue ablation in the vicinity of the cathode and anode.
