    Abstract: A medical device utilizing temperature sensing to identify or assess anatomical bodies or structures includes an elongate tubular member, at least one electrode, a thermal sensor, and a temperature response assessment system or component. The at least one electrode may be connected to the distal portion of the elongate tubular member, and the one or more electrode can be configured to provide energy or heat to a portion of an anatomical body or structure. The thermal sensor may be configured to measure the thermal response of the portion of an anatomical body or structure, e.g., tissue or blood pools. The temperature response assessment system or component can be coupled to the thermal sensor. In embodiments, the device may include a lumen and port opening, which may accommodate a tool, such as a needle. Methods for using temperature sensing to identify an anatomical body or structure are also disclosed.

    Abstract: A curved ablation catheter imparts ablative energy to target tissue, for example, along a trabecular slope, e.g., in the right atrium along the isthmus between the ostium of the inferior vena cava and the tricuspid valve. The catheter is formed with a preset curvature that, when deployed, both translates linearly and increases in radius to aid in the formation of spot or continuous linear lesions. A method of treating atrial flutter employs the curved ablation catheter.

    Abstract: An ablation device for creating linear lesions comprises a flexible support structure defining at least a partial curve; and an electrode disposed on the flexible support structure. The electrode comprises a pressure sensitive conductive composite that is configured for electrical communication with an electrical conductor and a flexible conductive outer covering that covers at least a portion of the pressure sensitive conductive composite. Electrical resistance of the pressure sensitive conductive composite varies inversely in proportion to pressure that is applied to the pressure sensitive conductive composite. Methods of creating linear lesions are also provided.

    Abstract: An ablation catheter is provided for ablating internal tissue of a patient. The catheter includes a distal end that is adapted to be inserted into a body cavity relative to a desired location therein (e.g., within the heart). An ablation electrode is connected relative to the distal end of the catheter for providing ablation energy to patient tissue. A heat sink is provided that is in thermal contact with the ablation electrode. The heat sink, in addition to being in thermal contact with the ablation electrode, is electrically isolated from the ablation electrode. This allows the heat sink to conduct heat away from the ablation electrode without dissipating electrical energy from the electrode. In this regard, the heat sink may prevent build-up of excess heat within the electrode that may result in blood coagulation and/or tissue charring.
