摘要 |
The invention provides methods and apparatus for regulating the temperature of a liquid medium while the liquid medium is within a patient. According to one exemplary method, a catheter (20) is provided havi ng a catheter body (22) with a proximal end (24) and a distal end (26). At least one lumen (28) extends between the proximal end (24) and a distal end (26) and an internal temperature altering region (14) is near the distal end. The catheter (20) is introduced into a body structure until the temperature altering region (14) is near a target area within the body structure. A liquid medium is introduced into the lumen so that the temperature of the liquid medium may be altered while passing through the temperature altering region (14).
