Claims
- 1. A balloon catheter for use in thermally mapping a portion of a body lumen, comprising:an elongate catheter having a distal end and having a balloon near the distal end, the balloon having an axial length and including a temperature sensitive material which when expanded into contact with a portion of the body lumen, will change color along its axial length based on the temperature of the body lumen contacting the balloon material, whereby analyzing the color changes along the axial length of the balloon will permit the determination of whether a portion of the lumen is at a temperature higher than the normal body temperature.
- 2. The balloon catheter of claim 1 wherein the temperature sensitive material is the balloon material.
- 3. The balloon catheter of claim 1 wherein the temperature sensitive material is a coating applied to the balloon.
