    摘要： An elongated catheter device with a distal balloon assembly is adapted for endovascular insertion. Coolant injected through the device may, in different embodiments, directly cool tissue contacting the balloon, or may cool a separate internal chamber. Plural balloons may be provided, wherein a secondary outer balloon surrounds a primary inner balloon, the primary balloon being filled with coolant and acting as the cooling chamber, the secondary balloon being coupled to a vacuum return lumen to serve as a robust leak containment device and thermal insulator around the cooling chamber. One or more sensors may be disposed between the balloons or the vacuum return lumen, to detect leaks and control the flow of fluid through the device. Examples of sensors include pressure and temperature sensors, optical sensors, magnetic flow switches and flow meters.

    摘要： The present invention may include a medical device having a handle, a catheter coupled to the handle, and an expandable element coupled to the catheter. The medical device may also include first and second elongate bodies that traverse a length of the handle and the catheter. A housing may be disposed within the handle, with the housing defining a first opening able to receive a portion of the first elongate body, a second opening able to receive a portion of the second elongate body, and a third opening opposite the first and second openings able to receive a portion of both the first and second elongate bodies. A separation element may be disposed within the housing, with the separation element defining a path able to receive a portion of the second elongate body, and whereby a portion of the first elongate body forms a loop around the separation element.

    摘要： A medical device includes a catheter body having a first injection lumen, a second injection lumen, and an exhaust lumen, where the first injection lumen provides a fluid flow rate greater than a fluid flow rate provided by the second injection lumen; an expandable element coupled to the catheter body in fluid communication with the first and second injection lumens; a cryogenic fluid source in fluid communication with the first and second injection lumens; a valve in fluid communication with the first and second injection lumens to selectively allow fluid flow to at least one of the first and second injection lumens; a pressure sensor in fluid communication with an interior defined by the expandable element; and a controller in communication with the pressure sensor programmed to regulate fluid flow through the first injection lumen based at least in part on a signal from the pressure sensor.
