    Abstract: A device and method suitable for remodelling the internal surface of a hollow vessel at least partially occluded by a mass is provided. The device comprises an elongate body having a distal end and a proximal end, the distal end comprising a tip portion located at the distal terminus of the body, and at least one heating element located proximally to the tip portion within the distal end. The at least one heating element is configured to be greater in dimension proximally than distally and thereby tapers towards the distal end. Furthermore, the at least one heating element is arranged so that it can be deployed outwardly from the body of the device and in so doing exert an expansion force on the hollow vessel. The at least one heating element is capable of delivering sufficient energy to remodel the internal surface, and if necessary caused localized ablation, of the hollow vessel without inducing closure of the hollow vessel.

    Abstract: An ablation catheter comprises a catheter body extending longitudinally between a proximal end and a distal end along a longitudinal axis; and an ablation element assembly comprising ablation elements connected to the catheter body, each ablation element to be energized to produce an ablation zone. The ablation elements are distributed in a staggered configuration such that the ablation zones of the ablation elements span one or more open arc segments around the longitudinal axis, but the ablation zones of all ablation elements projected longitudinally onto any lateral plane which is perpendicular to the longitudinal axis span a substantially closed loop around the longitudinal axis. Since the ablation zones do not form a closed loop, the risk of renal artery/vein stenosis is reduced or eliminated. Since the ablation zones of all ablation elements projected longitudinally onto any lateral plane span a substantially closed loop, substantially complete renal denervation is achieved.

    Abstract: An electrophysiology catheter includes an elongate catheter body having an elastically-deformable distal region predisposed to assume a spiral shape and a first plurality of electrodes disposed thereon. Each of the first plurality of electrodes includes an electrically active region limited to the inner surface of the spiral shape for use in non-contact electrophysiology studies. A second plurality of electrodes may also be disposed on the distal region interspersed (e.g., alternating) with the first plurality of electrodes, with each of the second plurality of electrodes having an electrically active region extending into the outer surface of the spiral shape for use in contact electrophysiology studies. The distal region may be deformed into a straight configuration for insertion into and navigation through the patient's vasculature, for example via use of a tubular introducer. As the distal region deploys beyond the distal end of the introducer, it resumes the spiral shape.

    Abstract: A medical device includes an insertion tube, having a longitudinal axis and having a distal end adapted for insertion through a body passage into a cavity within a body of a patient. An electrode is located on the distal end of the insertion tube and is configured to contact tissue in the cavity. A resilient member is contained within the distal end of the insertion tube and is configured, when unconstrained, to cause the distal end to bend away from the longitudinal axis in a curved shape and to straighten toward the longitudinal axis when subjected to a force.
