    摘要: A device for sealing an opening in a vessel includes an anchor attached to a suture. The anchor is inserted through the opening into the vessel, and the suture pulls the anchor against the vessel wall, forming a seal. A plug is inserted over the suture and is axially compressed toward the anchor, locking the elements in place. The suture is braided or woven outside of the anchor so that it may be stored and handled easily, and is unbraided, unwoven and/or untangled at its distal end inside the anchor, so that individual filaments within the suture may extend laterally within the anchor. The laterally extending filaments subtend a larger footprint within the anchor than a comparable footprint if the suture were to remain braided or tied into a knot within the anchor, which may more effectively distribute the retaining forces within the anchor.

    摘要: An elongated flexible medical device is inserted into a patient's body via a natural orifice, and advanced through the natural orifice to a location proximate innervated tissue that influences renal sympathetic nerve activity. The medical device can be advanced into a body organ and to a location within the organ proximate the innervated tissue. The organ may comprise an organ of the gastrointestinal tract or urinary tract. The medical device may be advanced through and beyond an access hole in a wall of the organ, and situated at a location proximate the innervated tissue. One or both of imaging and ablation energy is delivered from a distal end of the medical device to the innervated tissue. Innervated renal tissue can be ablated using various forms of energy, including RF energy, ultrasound energy, optical energy, and thermal energy.

    摘要: A catheter is configured to access a renal artery. A lumen of the catheter's shaft is dimensioned to receive a flexible actuation member which extends between the shaft's proximal and distal ends. The actuation member is moveable within the lumen and subject to elastic deformation, friction, and/or whip along its length. A flexible support member is coupled to a distal end of the actuation member and extendible beyond a distal tip of the shaft. An RF ablation electrode at a distal end of the support member is configured to ablated perivascular renal nerve tissue. A position converter at the distal end of the shaft is configured to convert movement of the actuation member into one or both of controlled rotational and axial movement of the support member and electrode to one of a multiplicity of stable circumferential positions substantially free of elastic deformation, friction, and/or whip impacting actuation member movement.

    摘要: An electrode is provided at a distal end of a catheter and dimensioned for deployment within a renal artery. A deformable cover of the electrode incorporates a force-activatable conduction apparatus. The cover is configured to conduct electrical energy only through a region or regions of the cover subject to deformation due to contact with a wall of the target vessel. The electrical energy is sufficient to ablate perivascular renal nerves proximate the deformed region or regions of the electrode cover. The cover is configured to prevent conduction of electrical energy through the cover in the absence of a deformation force applied to the cover.

    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.
