摘要： In some implementations, a method of ablating body tissue includes (a) locating an inflatable balloon portion of a cryotherapy balloon catheter at a treatment site internal to a patient's body, and inflating the inflatable balloon portion; (b) employing electrodes that are disposed on an expandable surface of the inflatable balloon portion to electrically characterize body tissue at the treatment site; (c) ablating the body tissue by supplying a cryotherapy agent to the inflatable balloon portion to cool the body tissue to a therapeutic temperature; (d) employing the electrodes to determine whether the ablating caused desired electrical changes in the body tissue; and (e) repeating (c) and (d) when it is determined that the ablating did not cause the desired electrical changes.

摘要： A catheter arrangement includes a flexible shaft and a balloon disposed at a distal end of the shaft and configurable for deployment within a target vessel of the body, such as a renal artery. Ablation electrodes, supported by a balloon wall, are arranged in a predefined pattern. The electrodes deliver electrical energy sufficient to ablate target tissue, such as perivascular renal nerves, proximate the target vessel wall when the balloon is in a deployed configuration. A cooling arrangement is encompassed at least in part by the balloon and provides cooling to at least the electrodes during ablation such that a location at which steady-state ablative heating begins is translated from an electrode-tissue interface at the target vessel wall to a location a predetermined distance away from the electrode-tissue interface.

摘要： Catheters and methods are provided for performing medical procedures, such as tissue ablation, adjacent the ostia of anatomical vessels, such as pulmonary veins. The catheter comprises an elongated flexible integrated catheter body having proximal and distal shaft portions and at least one operative element carried by the distal shaft portion. The distal shaft portion has a proximal section configured to be internally actuated (e.g., using a steering mechanism or pre-shaping the proximal section) to form a simple curve with an apex that can be inserted into the vessel ostium, an intermediate section pre-shaped to form a curve that bends opposite the simple curve, and a distal section configured to be placed into a non-radial relationship (tangential or oblique) with the vessel ostium when the apex of the simple curve is inserted into the vessel ostium. By this arrangement, the operative element is configured to be placed firmly in contact with tissue at a predefined radial location relative to the vessel ostium when the apex of the simple curve is inserted into the vessel ostium.

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.
