摘要： A device, method, and system for thermally affecting tissue. The device may generally include an elongate body, an actuation element slidably disposed within the elongate body, a balloon defining an interior chamber, a proximal neck, and a distal neck, the first neck being coupled to the distal portion of the elongate body and the second neck being coupled to the distal portion of the actuation element, retraction of the actuation element within the elongate body causing the treatment element to transition from a first configuration to a second configuration. The distal neck may be located external to the interior chamber in the first configuration and within the interior chamber in the second configuration. The device may also include a fluid injection element that is transitionable to an expanded configuration when the balloon is inflated, thereby enhancing the cooling capacity of the balloon.

摘要： The present invention provides a medical system, including a catheter defining an injection lumen, a chamber in fluid communication with the injection lumen, and an exhaust lumen in fluid communication with the chamber; a first temperature sensor positioned in the exhaust lumen proximal to the chamber; a second temperature sensor positioned in the chamber; and a console in electrical communication with the first and second temperature sensors, the controller modifying coolant flow through the medical device based at least in part upon a signal received from the first and second temperature sensor. The system may further include a thermally-conductive element circumscribing a substantial portion of the exhaust lumen proximal to the chamber, where the first temperature sensor is mounted to the thermally-conductive element, and the thermally-conductive element may include at least one of a braid, coil, and band.

摘要： A device and system for thermally affecting tissue that includes a balloon catheter with a reduced distal length for ease of navigation and that also includes a balloon that is more resistant to bursting and delamination. The balloon may include a proximal neck generally attached to an elongate body and a distal neck generally attached to a shaft disposed within the elongate body. The distal neck is turned inward to extend within the balloon chamber and the proximal neck may either extend within the chamber or extend proximally away from the balloon chamber. Alternatively, the device may include an inner balloon and an outer balloon, the distal necks of both being turned inward and extending within the inner balloon chamber. The proximal necks may both also be turned inward to extend within the chamber or the proximal neck of the outer balloon may extend away from the balloon chamber.

摘要： A method and system for providing lesion depth feedback during an ablation procedure. In particular, the method and system provide feedback data or information relating to lesion depth in myocardial tissue during a cryoablation procedure. A plurality of tissue temperature measurements may be transmitted from a plurality of thermocouples disposed on a cryotreatment element, which measurements may be used to determine a slope of change in temperature sensed by each thermocouple over time. The circulation of coolant through the treatment element may be adjusted when the slope changes. A change in slope may indicate that the cryoablation temperatures have passed through target myocardial tissue into non-target, non-myocardial tissue, which may result in collateral damage to structures near the heart.
