DUAL INJECTION TUBE CRYOCATHETER AND METHOD FOR USING SAME |
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. |
