Abstract
A system for exchanging heat with primary coolant flowing through an intravascular catheter or externally-applied pad to warm or cool a patient. A secondary heat transfer element can be engaged with a primary heat transfer element and is not grounded when the primary heat transfer element is fully engaged with the secondary heat transfer element during operation. In contrast, the secondary heat transfer element is grounded when the primary heat transfer element is at a predetermined disengaged position relative to the secondary heat transfer element.
