    摘要: A catheter includes a flexible shaft having a lumen arrangement and a length sufficient to access a target vessel of a patient. A balloon at the distal end of the shaft is fluidly coupled to the lumen arrangement. The balloon body comprises a first material and a second material different from the first material. The second material comprises a hydrophilic polymer that becomes electrically conductive in response to absorption of the conductive fluid. The fluid conductive regions facilitate perfusion of the conductive fluid through the balloon body to an inner wall of the target vessel during ablation of perivascular tissues. A cooling arrangement is configured for one of receiving a thermal transfer fluid from the lumen arrangement or facilitating perfusion of blood passing through the target vessel to cool the balloon body during ablation of the perivascular tissues.

    摘要: 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.

    摘要: A transducer supported by a positioning arrangement is placed within a renal artery at a desired location that is a predetermined distance from a reflector equal to an odd number of quarter wavelengths of acoustic energy emitted by the transducer. The positioning arrangement is actuated to transition from a low-profile introduction configuration to a deployed configuration within the renal artery thereby stabilizing the transducer at a desired location. Acoustic energy is emitted by the transducer so that it propagates axially along an outer surface of the target vessel to impinge the reflector, which can be biological or artificial. The emitted energy builds up to resonance at a point of reflection defined by a location of the reflector, and the amount of energy build up is sufficient to ablate perivascular renal nerves in the vicinity of the reflector.

    摘要: A device is disclosed for providing an indication as to the relative position of a vessel or artery opening thereby facilitating the choice of which several closure techniques to use. A disclosed device includes an outer tube and a collapsible foot slidably disposed within a distal end of the outer tube. The device may further include one or more threaded suture needles, a biodegradable plug or other wound closing device that is connected to another shaft. The collapsed or folded foot is pushed distally out of the tube and through the opening in the vessel whereupon the foot expands. Pulling the expanded foot in the proximal direction provides an indication as to the orientation of the opening in the vessel, which assists in determining the type of closing procedure to be carried out.

The central sheath and the alignment sheath each have a wall and a distal end where the wall of the alignment sheath is engaged to the wall of the central sheath. The wall of the central sheath defines a central lumen that has a central guide wire extending therethrough and the wall of the alignment sheath defines an alignment lumen that has an alignment guide wire extending therethrough. The distal end of the alignment sheath is positioned proximally to the distal end of the central sheath. The alignment apparatus has at least one stent disposed about one of the alignment guide wire or the central guide wire. The at least one stent has a pre-delivered state so that when the at least one stent is in the pre-delivered state, it is contained within at least one of the central sheath and the alignment sheath.
