摘要： Systems and methods supply ablation energy to an electrode in contact with tissue to form a tissue-electrode interface. The system and methods sense, simultaneously with ablation, at least two tissue temperature conditions using at least two tissue temperature sensing elements which are held within a carrier that is substantially isolated from thermal conductive contact with the electrode. The carrier holds the tissue temperature sensing elements in a spaced apart relationship in thermal conductive contact with tissue at different depths beneath the tissue-electrode interface. The systems and methods control the supply of ablation energy to the electrode based, at least in part, upon temperatures sensed by the tissue temperature sensing elements.

摘要： Systems and methods for ablating body tissue use an ablation element for contacting tissue to form a tissue interface. The ablation element is adapted to be connected to a source of ablation energy to conduct ablation energy for transmission by the ablation element into tissue at the tissue interface. The systems and methods include a tissue temperature sensing element held in a carrier in thermal conductive contact with tissue beneath the tissue interface. A mechanism attached to the carrier selectively advances the carrier relative to the ablation element to different depths beneath the tissue interface. A controller is coupled to the mechanism and to the tissue temperature sensing element to control advancement of the carrier beneath the tissue interface based, at least in part, upon tissue temperatures sensed by the sensing element beneath the tissue interface. Preferably, the controller controls the mechanism to locate the sensing element at the depth where the hottest sensed tissue temperature exists.

摘要： Systems and methods using an electrode able to transmit heating or ablation energy into tissue include first and second sensing elements associated with the electrode for measuring first and second temperatures. The electrode also includes a heating element in thermal conductive contact with the electrode for heating the electrode. The systems and methods sequentially activate the heating element and sense temperatures without transmitting tissue heating or ablation energy, and then transmit heating or ablation energy and sense temperatures without activating the heating element, to derive from the sensed temperatures a prediction of maximum tissue temperature.

摘要： Structures having asymmetric mechanical properties provide enhanced ability to support therapeutic or diagnostic elements in contact with tissue in an interior body region. The support structure includes a first region, which exhibits a first mechanical property affecting tissue contact, and a second region spaced from the first region about the axis, which exhibits a second mechanical property, different than the first mechanical property, affecting tissue contact. In a preferred embodiment, the first and second mechanical properties correlate with stiffness of the respective first and second regions, with the first region being more flexible (i.e., less stiff) than the second region. The first region, due to its greater flexibility, is more conformal to tissue than the second region. The less flexible (i.e., more stiff) second region imparts greater force against the tissue to urge the more flexible first region toward intimate tissue contact. In a preferred embodiment, the more flexible first region carries at least one therapeutic or diagnostic element.

摘要： Heart tissue is characterized by using pacing without inducing ventricular tachycardia (VT). With the tissue characterization, a patient's risk of developing VT can be determined and a slow conduction zone in the patient's heart can be determined. The characterization involves applying pacing signals with varying pacing cycle intervals to a chamber of the patient's heart to pace the patient's heart. The response signals generated by the paced heart are received and used as the basis for characterizing the patient's heart tissue.

摘要： Electrode assemblies and associated systems employ a nonporous wall having an exterior for contacting tissue. The exterior peripherally surrounds an interior area. The wall is essentially free of electrically conductive material. The wall is adapted to assume an expanded geometry having a first maximum diameter and a collapsed geometry having a second maximum diameter less than the first maximum diameter. The assemblies and systems include a lumen that conveys a medium containing ions into the interior area. An element free of physical contact with the wall couples the medium within the interior area to a source of electrical energy to enable ionic transport of electrical energy from the source through the medium to the wall for capacitive coupling to tissue contacting the exterior of the wall.

摘要： Elongated spline members are threaded through a hub to form depending spline legs. In one embodiment, the spline members are threaded through a puncturable material on the hub. In another embodiment, the spline members are threaded through a slotted hub, which is then encapsulated by a sealing, elastomeric material. In another embodiment, multiple spline members are looped and woven together beyond a distal end of the hub, and the distal end of the hub serves to exert a force that maintains the woven relationship of the spline members. The spline legs, which radiate from the hub, preferable carry one or more diagnostic or therapeutic elements, such as electrodes. Preferably, a base constrains the terminal ends of the spline legs in a normally expanded geometry between the hub and base.

摘要： Collapsible electrode assemblies and associated methods employing a structure having an axis and a distal end. The structure comprises a wall peripherally enclosing an interior. The structure is adapted to selectively assume an expanded geometry having a first maximum diameter about the axis and a collapsed geometry having a second maximum diameter about the axis less than the first maximum diameter. An electrically conductive material is carried by the wall, forming an electrode region adapted to conform to both the normally expanded geometry and the collapsed geometry of the structure. In one implementation, a flexing element in the interior of the structure bends within the interior along the axis of the structure to displace the distal end relative to the axis. In another implementation, a stilette element within the interior of the structure imparts axial force upon the distal end along the axis of the structure, thereby axially elongating or shortening the structure.
