Abstract

An expandable device (40) for profiling the wall of a hollow body organ includes a flexible, expandable member (42) capable of conforming to the wall of a cavity or hollow body organ. A temperature sensor (48) within the interior of the expandable member can move about and measure the temperature at different locations. One expandable member can be an elastomeric balloon for conforming to the walls of the hollow body organ and which can be coated or doped with a material (46) that responds to a change of temperature of the cavity wall. This change can be assessed by the sensor, e.g., a fiberoptic that can transmit light and collect the reflected light. The fiberoptic can have a reflection mechanism (50) at its tip to direct the angle of incidence. The controller can measure and process the collected signal to produce a graph representing, the temperature profile.
