    摘要： A medical device including a catheter body defining a proximal portion and a distal portion. An expandable element is included defining a proximal end and a distal end, the proximal end being coupled to the distal portion of the catheter body. A tip element coupled to the distal end of the expandable element is included, the tip element including a shaft slideably receivable within a portion of the catheter body. A tensioning element coupled to the shaft and disposed within the expandable element is included, the tensioning element being engageable with the distal end of the catheter body and biasing the expandable element toward a pre-determined longitudinal position. An electrode array defining a substantially closed loop affixed to and extending from the tip element is also included.

    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.

    摘要： A medical device and method are provided for mapping and therapeutic treatment, which may include a source of cryogenic fluid, a balloon or other expandable member in fluid communication with the source of cryogenic fluid, and a plurality of electrodes on the expandable member. The medical device may include a catheter or elongate body, and the electrodes may take the form of longitudinal strips. The expandable member may take the form of an inner and outer balloon, and the electrodes may be on the outer balloon. The electrodes may be on a proximal or distal conical portion of the expandable member, or both. An electrical insulator may be provided covering a portion of the electrodes.
