    摘要: Systems for nerve modulation are disclosed. An example system may include a first elongate element having a distal end and a proximal end and having at least one nerve modulation element disposed adjacent the distal end. The nerve modulation element may be an ultrasound transducer. Activation of the nerve modulation element may ablate multiple regions of a target area.

    摘要: A catheter for thermal modulation of renal nerves via thermal ablation, the catheter including a catheter shaft including a distal end, a proximal end, and two lumens—a first lumen and a second lumen—extending therethrough. A thermal heating element is located proximate the distal end of the catheter shaft. In addition, a phase-change cooling mechanism is configured to extract heat away from the thermal heating element. The phase-change cooling mechanism involves vaporization of a liquid refrigerant circulated to the distal end of the catheter shaft through the first lumen into a gas and exhausting the gas to the proximal end of the catheter shaft through the second lumen.

    摘要: A first spacing structure is provided at a distal end of a first catheter. The first spacing structure is configured to position at least one arterial electrode at a predefined distance away from a wall of the renal artery. A second spacing structure is provided at the distal end of the first catheter or at a distal end of a second catheter. The second spacing structure is configured to position at least one aortal electrode at a predefined distance away from a wall of the aorta. The arterial and aortal electrodes are operable as a bipolar electrode arrangement. The first and second spacing structures respectively maintain the arterial and aortal electrodes at a predefined distance away from the renal artery and aortal walls while electrical energy sufficient to ablate perivascular nerve tissue adjacent the renal artery and aortal walls is delivered by the bipolar electrode arrangement.

    摘要: Systems for nerve modulation through the wall of a blood vessel are disclosed. An example system for nerve modulation may include an elongate member extending along a central elongate axis and having a proximal end and a distal end. The elongate member may have a radially expandable member disposed proximate the distal end. A tubular sheath may be cooperatively engaged with the expandable member such that the expandable member is collapsed when in the sheath and can expand when moved distally relative to and past a distal end of the sheath. The expandable member may include a plurality of electrodes and a plurality of spacer struts. Each spacer strut may be configured such that when the self-expanding member is in an expanded state the spacer strut extends out radially further than the electrodes from the central elongate axis.
