Abstract

A device and method for sensing the temperature profile of a hollow body organ (12) includes a catheter (18) and a hollow guidewire (20). The guidewire is configured as a plurality of helical loops (26) of greater diameter than the catheter when unconstrained. When constrained within the catheter, the guidewire can be advanced to a region interest in hollow body organ. The catheter can be withdrawn, leaving the guidewire in place in an expanded configuration wherein the helical loops contact the inner wall of the hollow body organ. A temperature sensor is moveable within the guidewire to sense the temperature at multiple locations.
