    • A first catheter is dimensioned for deployment within a renal artery. A second catheter has a shaft with an outer diameter smaller than an inner diameter of the first catheter's open lumen. A gap is formed between the shaft and the first catheter when the second catheter is situated within the first catheter. The gap facilitates transport of a fluid, such as imaging contrast media, along the first catheter. An electrode arrangement at the distal end of the shaft is configured to deliver ablative energy to perivascular renal nerves, and has an outer diameter about the same size as the inner diameter of the first catheter such that a fit therebetween substantially blocks fluid flow within the gap yet provides for relative movement between the electrode arrangement and the luminal wall. A conductor extends between the proximal and distal ends of the shaft and is coupled to electrode arrangement.
    • 第一个导管的尺寸用于部署在肾动脉内。 第二导管具有外径小于第一导管开口腔内径的轴。 当第二导管位于第一导管内时,在轴和第一导管之间形成间隙。 该间隙便于沿着第一导管输送诸如成像造影剂的流体。 在轴的远端处的电极布置被配置为将消融能量递送至血管周围肾神经,并且具有与第一导管的内径大致相同尺寸的外径,使得其间的配合基本上阻挡在间隙内的流体流动 而是提供电极装置和腔壁之间的相对运动。 导体在轴的近端和远端之间延伸并耦合到电极装置。

    • A flexible catheter includes a magnetically permeable element provided at its distal end. The magnetically permeable element is configured for placement within the renal artery. External coils, positionable on anterior and posterior portions of a patient in proximity to the renal artery, are coupled to a generator which energizes the external coils to create a high-frequency oscillating magnetic field in body tissue between the external coils including the renal artery and perivascular renal nerve tissue. The magnetically permeable element serves to concentrate the magnetic field in a region near the renal artery. The concentrated magnetic field induces high frequency electric current sufficient to ablate the perivascular renal nerve tissue proximate the renal artery. A cooling arrangement can be provided at the catheter's distal end and configured to provide cooling to the renal artery during ablation of the perivascular renal nerve tissue.
    • 柔性导管包括设置在其远端处的导磁元件。 导磁元件构造成放置在肾动脉内。 位于靠近肾动脉的患者的前部和后部的外部线圈被耦合到发电机,该发电机激励外部线圈,以在包括肾动脉和外周线圈的外部线圈之间的身体组织中产生高频振荡磁场, 血管周围肾神经组织。 导磁元件用于将磁场集中在肾动脉附近的区域。 集中的磁场诱发高频电流足以消融肾动脉附近的血管周围肾神经组织。 可以在导管的远端处提供冷却装置,并且构造成在血管周围肾神经组织的消融期间向肾动脉提供冷却。

    • An annuloplasty device having a plurality of corkscrew anchors is herein disclosed. In some embodiments, the annuloplasty device includes a core wire extending along the length of the device, and at least one corkscrew wire which is operably connected to the corkscrews to screw the corkscrews into heart tissue. In certain embodiments, one or more of the corkscrew wires includes a drive key and the corkscrew anchors are connected to a sleeve with a keyway that engages the drive key on the corkscrew wires. In addition, in some embodiments, the device includes a retractable sheath, which is disposed over the corkscrews to protect them during insertion of the device.
