  • Publication number: 20200038105
    Abstract: A method for the treatment of a patient for the purpose of lowering blood pressure and/or treating other medical conditions such as cardiac arrhythmias. A catheter having an ablation element is placed inside the body of a patient and is directed to a targeted location either on in the abdominal aorta where the right or left renal arteries branch from the aorta at or near the superior junction or ostia or on the inside of the inferior vena cava near the junction with the right renal vein or in the left renal vein at a position spatially near where the left renal artery branches from the abdominal aorta. Catheters designed for use in the method where these targeted locations are also disclosed and claimed.

  • Publication number: 20190336209
    Abstract: An ablation catheter adapted for use with a guide wire has a 3-D shaped portion that carries ring electrodes for ablating a vessel or tubular region, including the renal artery. The 3-D shaped portion, for example, a helical portion, enables the ring electrodes to contact an inner surface of the vessel at a plurality of locations at different depths along the vessel to form a conduction block without forming a closed conduction loop which would otherwise increase the risk of stenosis of the vessel. In one embodiment, the catheter has a lumen with entry and exit ports to allow the guide wire to pass through the lumen but bypass the 3-D shaped portion. In another embodiment, the catheter has outer bands providing side tunnels through which the guide wire can pass through.

  • Patent number: 10285751
    Abstract: An ablation system observes and monitors ablation parameters, including temperature, impedance, and/or the system's own closed-loop response to these ablation parameters. The system comprises a catheter with electrodes and a detection circuitry configured to detect an ablation parameter for each electrode, a controller coupled to the catheter, the controller having a processing unit and a memory storing instructions that, when executed by the processing unit, cause the processing unit to: receive a detected ablation parameter for each electrode from the detection circuitry, determine when a detected ablation parameter violates a defined ablation parameter for each electrode, control a power supplied to each violating electrode to have a reduced power, detect a rate of power reduction for each violating electrode, and stop the power supplied to each violating electrode when a respective detected rate of power reduction exceeds a threshold rate of power reduction.
