Abstract
The invention provides methods and apparatus for determining physiological characteristics of body lumens, such as the length of a blood vessel. According to one exemplary method, the distance between a first target location and a second target location within a lumen are measured by aligning a first marker on a first elongate member disposed within a lumen with the first target location. A second marker on a second elongate member disposed within the lumen is aligned with the second target location. The distance between the first and second markers is then measured, and the measured distance corresponds to the distance between the first and second target locations.
