    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 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 method and device for treating tissue with temperature-sensitizing adjuvants to enhance the effects of ablation therapy. The method may comprise identifying tissue to receive ablation therapy, treating the tissue with a temperature-sensitizing agent, and activating an ablation therapy device proximate the treated tissue. The device may comprise a cryo-sensitizing adjuvant operable in association with a cryotherapy device, the cryo-sensitizing adjuvant enhancing the effectiveness of tissue destruction upon application of temperatures below 0° C.
