ABSTRACT:
The invention provides apparatus for determining physiological characteristics of body lumens, such as the length of a blood vessel. A catheter allows measurements of the distance between a first target location and a second target location within a lumen 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 directly measured from spaced-apart calibration marks along the second member, and the measured distance corresponds to the distance between the first and second target locations.
